The purpose of this bibliography is to provide personnel of the U.S. Forest 
Service and U.S. Bureau of Land Management with a comprehensive annotated 
list of articles, books, manuscripts, etc. on Wild Horses. Because of the 
limited information available specifically on Wild Horses, much of the in- 
formation included in the bibliography is from articles on domestic horses 
or from data on other members of the Equidae . 

The bibliography is divided into sections for easier use and within each sec- 
tion alphabetically by author. 

At the end of each citation a code appears in parentheses giving the location 
of publication availability. Many of the articles will also be available at 
local public and university libraries.

A discussion of the Spanish Mustang registry founded in 1957. 
To date 300 horses are registered, not counting current 
foals. Included in the registry are horses descended from 
those acquired by Ferdinand and Bob Brislawn, wild horse 
ranchers . 

International Society for the Protection of Mustangs and Burros. 
Newsletter. Irregular. (140 Greenstone Drive, Reno, Nevada 
89502) . (DPL) 

This newsletter discusses the activities of the society and 
outlines current national events such as new legislation 
concerning wild horses . Violations of laws protecting wild 
horses are mentioned often accompanied by eyewitness accounts 

McMullen, Rosemarie. 1966. The mustang. Western Horseman . 
31(10): 26, 53. (DPL) 

The American Mustang Association was formed to ensure that 
mustangs survive. The goal of the Association is to produce 
the ideal Andalusian type characteristics as the standard 
conformation of the mustang. Shows for these registered 
horses are sponsored by the Association. 

National Mustang Association. 1971. Help save the mustangs I 
Equestrian Trails . 26(7): 27. (DPL) 

The Association explains that they have placed a down- 
payment on a ranch in Nevada to which wild mustangs and burros 
can be taken. They have formed a group whose services are 
offered to ranchers who wish these animals removed from 
their lands . The article describes the need for funds and 
legislation, and explains how they plan to campaign through- 
out the country to save the mustangs. 

Richards, Lawrence P. 1958. The Spanish Mustang Registry. 
Western Horseman . 24(10): 16, 93-94. (DPL) 

The purpose and formation of the Spanish Mustang Registry 
are discussed. The purpose of the organization and registry 
is to ensure that the remaining horses with the character- 
istics of the Spanish "Barb" are registered and preserved. 
They do not want Spanish "Barbs" hybridized with other 
horses as was done in the past to genetically improve the 

Tinker, Nancy. 1969. Broomtail registry. Horse Lover's 
Magazine . 33(4): 38-39, 62. (DPL) 

The author relates the fate of what was once over a million 
wild horses, descended from the Spanish Andalusians. She 
describes the efforts of Robert and Ferdinand Brislawn to 
form a breeding herd of mustangs over a period of thirty 
years, gives the standards for which they have aimed, and 
discusses how some of their herd animals have been caught 
in the wild.

Nevada. (P. 0. Box 555, Reno, Nevada 89504). (DPL) 

This newsletter alerts members of the organization of 
activities concerning wild horses such as legislation, 
roundups, grants, studies, etc. Members are also urged to 
write letters to appropriate government officials to main- 
tain protection for wild horses. Wild horses that will be 
available for adoption are mentioned in the newsletter. 


Anonymous. 1971. Family: Equidae. World of Wildlife . 1(5): 
86-89. (DPL) 

The first horse, Eohippus from the Eocene period, is traced 
to the present day Equu s . Mention is made of the changes in 
toes, skull, and dentition. A brief description of the 
general habits of Equus spp. covers their senses, dentition, 
habitat, and digestion. Illustrated with maps, photographs 
and charts. 

Alexander, F. 1963. Digestion of the horse, p. 259-268. In: 
D. P. Cuthbertson, ed. Progress in Nutrition and Allied 
S ciences . Olive and Boyd, Edinburgh. (DPL) 

A review of available literature on horse digestion, this 
article covers gastric digestion, mechanics of gastric 
digestion, digestion in the small intestine, digestion in 
the large intestine, pharmacological studies, and micro- 
biology. Extensive list of references. 

American Association of Equine Practitioners. 1966. Official 
G uide for Determining the Age of the Horse . Fort Dodge 
Laboratories , Fort Dodge, Iowa. n.p. (CSU) 

Thoroughly illustrated with line drawings which depict 
teeth of horses at various ages as generally seen today in 
America. Descriptive legends accompany the drawings. This 
text is based on the premise that teeth provide the most 
precise tool available for the determination of the age of 
a horse. Teeth appear, develop, wear, change form and are 
shed with a regularity that veterinarians have learned to 
recognize with a reasonable degree of accuracy. 

Bell, R. H. V. 1970. The use of the herb layer by grazing 

ungulates in the Serengeti, p. 111-124. In: A. Watson, ed., 
Animal Populations in Relation to their Food Resources . 
Blackwell, Oxford. (DPL) 

The seasonal use of grazing areas by African ungulates has 
developed in a sequential manner dictated by the growth 
form of the vegetative layers in relation to topography. 
The animals are independent of each other's effect on 
vegetation only during the wet season when there is abundant 
forage. Analysis of diet was performed on four of the ungu- 
lates; zebra, wildebeest, topi and Thomson's gazelle. Freshly 

ingested stomach contents were divided into two categories 
of vegetation: dicotyledons and monocotyledons. The zebras 
led the grazing succession. They opened up the herb layer 
for other animals by consuming the coarses, low protein, 
high crude fiber vegetation. To explain the ability of the 
zebra to survive on a low quality diet, the digestive system 
of horses is described and compared to that of the ruminant. 
Diet selectivity, interspecific associations, and alterna- 
tive grazing successions are discussed. The author con- 
cludes that the presence of one species in the grazing 
succession is beneficial to the others. 

Bell, Richard H. V. 1971. A grazing ecosystem in the Serengeti. 
Scientific American . 225(1): 86-93. (DPL) 

This study examines the migration and grazing- patterns of 
three species of large herbivore (wildebeest, zebra, and 
Thomson's gazelle) in the Serengeti National Park. The 
animals make use of the herb layer in a regular sequence: 
first the zebras graze and trample the coarser, stemmier 
vegetation, they are followed by the wildebeest who in 
turn prepare the area for the delicate, selective grazing 
of Thomson's gazelle. Analysis of the stomach contents of 
the three species revealed that the selected vegetation 
corresponded to their position in the grazing succession. 
The reason for this sequence of grazing is due to the 
differences in the digestive systems of ruminants and non- 
ruminants and body size which has an effect on their rate 
of metabolism. If this grazing succession broke down there 
is a possibility that the Thomson's gazelle might not be 
able to survive. 

Berliner, Victor R. 1959. The estrous cycle of the mare, 

p. 267-289. In: H. H. Cole and P. T. Cupps, eds., Repro - 
duction in Dome st ic Animals . Academic Press, N. Y. (DPL) 

This paper is divided into five parts. Part I is concerned 
with the breeding season of mares; part II the pattern of 
the estrous cycle; part III the physiological and histologi- 
cal changes in the reproductive system; part IV the behavioral 
pattern of the cyclic mare; and part V the adaptations of 
the breeding program to cyclic events. The author discusses 
and comments on the inconsistencies as well as areas of 
agreement within the literature on the estrous cycle of the 

Slakeslee, Jodean Kay. 1974. Mother- Young Relationships and 
Related Behavior Among Free-Ranging Appaloosa Horses . M.S. 
Thesis, Idaho State University. 113 p. (DPL) 

Approximately 125 free- ranging Appaloosa horses in Idaho 
were studied by direct observation in a 5,000-acre pasture 
from June through August, 1973. The horses were also 
observed at a 3,000-acre winter pasture in Idaho. The 
author discusses the following areas: the estrus cycle, 
gestation period, changes just prior to parturition, foal- 
ing, post partum activity, imprinting, bringing the foal 
into the group, nursing, recumbency and resting, recognition, 
foal elimination, foal grazing and drinking, foal's explora- 
tory and investigative behavior, and relationships between 
foals and other group members. A well-documented study 
with a thorough list of references.

Burkhardt, J. 1947. Transition from anestrus in the mare and 
the effects of artificial lighting. Journal of Agricult ural 
Scienc e. 37: 64-68. (DPL) 

Anestrus mares were divided into four treatment groups. The 
Group I mares received an additional period of artificial 
light. Group II mares were exposed to ultraviolet light 
which was gradually increased during a four- week period. 
The light was applied only to their flanks and bellies and 
their eyes were hooded. Group III mares were kept in con- 
finement under normal light conditions. Group IV mares 
were allowed to run in the paddock. In Group I ovarian 
stromal growth, increased vascularity of the cervix and 
vagina, plus shedding of the coat occurred within 15-30 
days from the start of treatment. Follicles appeared soon 
after and the first appearance of estrus occurred about 30 
days earlier than in the other groups. The author concluded 
that light affects reproductive activity in the mare and, 
since irradiation of the ovaries with ultraviolet light did 
not change the normal occurrence of estrus, he suggested 
that the eye was probably the receptor organ.

affecting reproduction, p. 473-488. In: H. H. Cole and 
P. T. Cupps, eds., Reproduction in Domestic Animals . 
Academic Press, New York. (DPL) 

The authors review the evidence of the role of environmental 
factors in the reproductive physiology of individual domestic 
animals. Discussion is grouped under four headings: light, 
temperature and humidity, social stimuli, and other factors. 
The introduction covers these four factors as they relate 
to the available evidence on the various species that have 
been studied. The specific animals include the horse, 
rabbit, sheep, cattle, swine, and goat. Most of the evidence 
on the horse concerns the effect of light on the estrus cycle 
of the mare and its effect on the quantity and quality of 
semen from the stallion. The authors state that the specific 
effects of temperature on reproductive activity in the mare 
have not been critically studied. Extensive references.

"An extended study on the length of the estrus period shows 
variation of from, three to 54 days and diestrus from five 
to 30 days with averages of seven to eight days and 11 to 
16 days, respectively. The time and condition of ovulation 
is pointed out together with its variation by treatments 
with pregnancy urine and gonodotrophic hormones and the 
influence of these upon pregnancy and the length of the 
cycles." Biological Abstracts. 

Denhoff, Gay. 1974. Should the Wild Horse of Alberta be Pro- 
tected? University of Calgary. 25 p., 6 maps. (DPL) 

The author discusses wild horses which inhabit an area just 
east of the Rocky Mountains in Canada. There is a geologic 
description of the area along with a discussion of the types 
of forests found there. The author gives a detailed listing 
of plant species found in each of the ecological zones 

mentioned. The main herbivore wild life in the wild horse 
ranges are elk, deer and moose. Approximate locations of 
herds are given. The author estimates that there are 
roughly a total of 1000-1500 horses in the Alberta Province. 
Feeding and watering habits of wild horses are discussed. 

Edwards, Gladys Brown. 1970. The long and short of it. 
Arabian Horse World . 10(11): 87-94. (DPL) 

The Exterior of the Horse , a book by two French authors, 
Boubaux and Barrier, printed in 1884, is quoted extensively 
on the relationship between the length of a horse's loins 
(lumbar vertebrae) and that of its back (thoracic vertebrae) 
Such problems as foraging are analyzed in some detail. The 
number of lumbar vertebrae is also discussed in relation to 
Arabians, other breeds of horses, zebras, and donkeys. 
Three tables from several sources are reproduced, listing 
the number of vertebrae in these two areas plus those in 
the croup (sacral) for these kinds of equines plus the 
Shetland pony and the Przewalski horse.

Estes, Richard D. 1974. Zebras offer clues to the way wild 
horses once lived. Smithsonian . 5(8): 100-107. (DPL) 

The paper is based on the findings of the social behavior 
study on Burchell's zebras done by the ethologist Hans 
Klingel over a three-year period in Africa. It describes 
in detail the family social organization of the zebras. 
The article is written for a general audience and is 
scientific in scope. 

Feist, James Dean. 1971. Behavior of Feral Horses in the Pryor 
Mountain Wild Horse Range . M. S. Thesis. University of 
Michigan. 129 p. (DPL) 

"The objectives of this study were to investigate the be- 
havior patterns, social organization, and population struc- 
ture of the wild horses of the Pryor Mountains, Wyoming- 
Montana. To facilitate an accurate account of the population 

structure and social organization, the entire herd on the 
Range was identified as individuals. Documentation of 
daily and seasonal activity patterns, movements, possible 
home ranges and/or territories, dominance interactions, 
leadership, and breeding relationships was made. Qualita- 
tive and quantitative descriptions and photographs of 
stereotyped behavior acts were taken." Behavior patterns 
were analyzed and compared to the behavior of other Equidae 
from other geographical locations. 

Glover, J. and D. W. Duthie. 1958. The nutritive ratio/crude 

protein relationships in ruminant and non-ruminant digestion. 
Journal of A g ricultural Science 50: 227-229. (DPL) 

The author determined that the nutritive ratio of animal 
food was significantly related to the crude-protein content 
of that particular food in both ruminant and non- ruminant 
digestion. This confirms that a relationship exists between 
the total crude protein and digestible protein in ruminant 
feed. It also strongly suggests that there should also be 
a relationship between these two proteins in non- ruminant 
feeds. The author warns that it would be unwise to assume 
a constant relationship between the nutritive ratio and the 
crude protein content of feed until more data are available 
on non- ruminants at low-protein levels. 

Gremmel, Fred. 1939. Coat colors in horses. Journal of 
Heredity . 30(10): 437-445. (DPL) 

A detailed heredity scheme is expounded for color inheritance 
in horses, based upon observations, clinical tests, and 
histological examination. Hypothesis holds that gene com- 
binations on three major loci (probably modified by accessory 
genes) have quantitative and cumulative effects on pigment^ 
production, resulting in various colors and shades. Certain 
color patterns are due to independent dominant genes showing 
no epistasis toward each other. Further details of patterns 
are discussed.

Hall, Ron and J. F. Kirkpatrick. 1975. Biology of t he Pryor 
Mountain Wild Horse . Bureau of Land Management, Salt Lake 
City, Utah. Unpublished paper, 21 p. (DPL, USDI) 

"Data regarding population size and dynamics, herd distribu- 
tion, behavior, social structure and food habits were col- 
lected for approximately 130 wild horses in the Pryor Moun- 
tains of south-central Montana, from 1969 through 1973. 
The horses did not have any dominant color description, but 
palaminos, appaloosa and whites were totally absent. Mature 
females had an average weight of 600-750 pounds and mature 
males (5 years and older) ranged between 800-900 pounds. 
The hoof wall was at least twice the thickness as that of 
the domestic horse. There were approximately 130 horses on 
the range. The sex ratio was 60% male and 40% female. A 
10- to 11-year-old horse was considered old. The oldest 
horse was 14 and the average age was 6.4 years. Survival of 
colts was approximately 3-4%. In 1971 the young/adult ratio 
was 11/100 and the young/female ratio was 24/100. In 1972 
the young/adult and young/female ratios were 16/100 and 
24/100 respectively. The rise in the young/adult ratio in 
1971 was due to the removal of 30 adult males. The breeding 
season extended from late March to mid-July with peak activ- 
ity in early May. The gestation period was approximately 
340 days with foaling occurring from early April to July. 
The majority of males and females did not breed until at 
least three years of age. The effects of photoperiod on 
reproduction are unknown with respect to the female and 
probably play an important role in the male. Average harem 


group size was 3.4. The harem was composed of a lead mare, 
a stud whose function was breeding and holding the unit 
together, and other subordinate animals. Larger harem 
groups sometimes contained two males and both of them bred 
on occasion. Males born to the unit were sometimes driven 
off as yearlings, while other groups tolerated young males 
for as long as three years. Stud groups, composed of young 
stallions not yet capable of obtaining a harem had a much 
looser organization than did the harem groups. The stud 
groups were led by a dominant stallion. Individual members 
sometimes joined other all-male groups. The horses in the 
Pryors had seasonal home ranges but did not establish 
territories. In general, distribution was dictated by 
availability of water and forage and weather conditions. 
The major items in the horses' diet were bluebunch wheatgrass 
(Agropyron spicatum) and sandberg bluegrass ( Poa secunda ) ." 

Hanauer, Elsie. 1973. The Science of Equine Feeding . A. S. 
Barnes, New York. 78 p. (DPL) 

Beginning with a complete explanation of the horse's digest- 
ive system and its functions, the author delves into basic 
food requirements, vitamins and minerals. Factors influ- 
encing feeding principals, special cases, changing the diet, 
and feeding schedule are then discussed. A section on 
specialized diets is followed by a section covering diseases 
caused by faulty nutrition. 

Klingel, Hans. 1965. Notes on the biology of the plains zebra 
Equus quagga . East African Wildlife Journal. 3:86-88. (DPL) 

The author observed thirty-nine harem groups and 15 stallion 
groups for two years, another ten harem groups and 22 
stallion groups for one year, for a total of about 500 
animals. The results of the study are outlined in the 
following sections: social structure, seasonal distribution 
and foaling, foaling rate and intervals, sex ratio, and 
age at sexual maturity.

IUCN Publications new series No. 24. International Union 
for Conservation of Nature and Natural Resources, Morges , 
Switzerland. (DPL) 

In the Equidae two types of social organization have evolved. 
The plains zebra ( Equus quagg a) , mountain zebra (E. zebra ) , 


horse (E. przewalskii ) and possibly also the Asiatic wild 
ass (E. h emionus ) live in coherent family groups, consisting 
of one stallion, with one to several mares and their young. 
Surplus stallions are found in stallion groups. The young 
leave their original families in a set pattern. No terri- 
tories are established in these species. In the Grevy 
zebra ( E. grev yi) and the wild ass (E. african us) the 
the stallions maintain large territories which they, however, 
only defend under certain conditions, i.e. when an estrus 
mare is near the boundary. Apart from the mare- foal rela- 
tionships there are no personal bonds between any two or 
more individuals. Most of the equine populations live in 
areas with marked seasonal variation. In the non- territorial 
species the reproductive groups migrate as units. In the 
territorial species the sexes segregate for part of the 
year, a feature which will certainly influence the repro- 
ductive rate, especially in areas with irregular rainfall. 

Klingel, Hans. 197 2. Social behavior of African Equidae. 
Z oologica African a. 7(1): 175-185. (DPL) 

Two basically different forms of social organization were 
discovered in the equids. Type one is represented by the 
plains zebra, Equus quagga and by the mountain zebra, E. zebra . 
Type two comprises Grevy 1 s zebra, E. grevyi and the wild ass, 
E. africanus . Differences are found between these two 
groups in territorial and family behavior patterns. The 
evolution of equine sociology is discussed. 

McKnight, Tom L. 1959. The feral horse in Anglo-America. 
Geographical Review . 49: 506-525. (DPL) 

"The principal aim of the study on which this paper is 
based was to gather as much information as possible concern- 
ing the current distribution of feral horses in Anglo- 
America and the land-use problems resulting from that dis- 
tribution. Most of the data were gathered by means of a 
questionnaire." A very thorough well-documented section 
on the history of the feral horse leads to the discussion, 
tables, and map of the present population, its problems 
and advantages. 

Odberg, Frank Olof. 1973. An interpretation of pawing by the 
horse ( Equus caballus ) , displacement activity and original 
functions. Saeugetierkd Mitt . 21(1): 1-12. (DPL) 

The original function of pawing was as part of the nutritive 
and grooming behavior and as the marking of territory. Pawing 


was also interpreted as displacement activity; by the 
sight of unreachable food, while eating, while waiting 
before work (racing, pulling the cart), by the stallion 
before serving the mare, and as part of the threat-

Movement Patterns of Wild H or ses in the Wassuk Range of 
Western Nevada . M. S. Thesis, University of Nevada, Reno. 
39 p. (DPL) 

The unique methods of gathering data for this study included 
observations of such signs as tracks, hair deposits, dung 
piles, and shade and rubbing trees. The author studied, 
measured, and then drew to scale the particular hoof prints 
of each horse in a band. Color was determined by correlating 
the tracks of each animal at places where they would lose 
body, mane and tail hair such as rubbing trees and rolling 
places. Sex was determined by urination patterns and tracks 
close together such as a mare and a colt. Movement patterns 
were plotted on maps by following fresh tracks. Validity 
of data was confirmed by visual contact, the use of a blind, 
spotting scope, and aircraft. The author reported that the 
horses in the Wassuk range defended only a small portion of 
their home range as territory. Home ranges of harem groups 
were cube-shaped while that of lone horses was linear. 
There was a good colt crop and survival in 1970 but a very 
poor crop in the preceding ten years. The text contains a 
description and map of the study area plus illustrations

Smythe, R. H. 1966. The Mind of the Horse . Stephen Greene 
Press, Brattleboro, Vermont. 123 p. (DPL) 

The author, a veterinarian, describes the horse's instincts 
as a herd animal, and cites the adjustments it is required 
to make in carrying out patterns of behavior entirely 
opposed to its natural impulses. Then he examines the 
horse's sensory advantages and handicaps. His chapter on 
vision examines the make-up and placement of the eye in 
various breeds and, with the aid of excellent diagrams and 
photographs, explains how a horse's actions are governed by 
what it is able to see. Equally enlightening are his 
sections on equine hearing, smell and taste, tactile sensa- 
tions, emotions and motivations. 

Smythe, R. H. 1967. The Horse: Structure and Movement . 2nd ed. 
Revised by Peter C. Goody. J. A. Allen, London. 184 p. (KSU) 

The author discusses the anatomic structures which are re- 
sponsible for the appearance of the horse and the relation- 
ship of musculo-skeletal system to movement. The book is 
divided into four sections: bones and joints; skin and sur- 
face contour of the body; functions of certain parts of the 
horse at rest and in motion; and an appendix. Text is sup- 
plemented with illustrations.

aspects of fertility in horses raised under western range 
conditions. Journal of Animal Science . 3(3): 233-241. (DPL) 

Fertility data and analysis for 209 mares bred to 14 stallions 
over a 15-year period at the U. S. Range Livestock Experi- 
mental Station, Miles City, Montana are given. Effects of 
several variables on fertility rate for these domestic 
horses are examined. Sex ratios of foals and causes of 
deaths are described.

in the lumbar spine of the horse--a descriptive and statisti- 
cal study. American Journal of Veterinary Research . 23(96): 
939-947. (DPL) 

Large size in an animal poses muscular disadvantages for 
locomotion. In the horse and other animals this is compen- 
sated for by stiffness of the posterior spine. Stability 
in the horse is augmented by lateral joints in the lumbar 
region. These lateral joints are unique to all horses, 
domestic, wild, or prehistoric. The joints vary from four 


to seven with the number largely dependent on the length of 
the lumbar spine which is dependent upon the number of 
lumbar vertebrae. The author examined 245 skeletons of 
members of the horse family and found variation in all breeds 
and species. The sources of skeletal material by breed and 
species are listed. The functions of the lateral joints 
are discussed. The text includes photographs and tables. 
Included is a summary in Spanish. 

Storrar, James Andrew. 1974. Feral Horse Habitat Analysis . 
B. S. Thesis, University of British Columbia. (DPL) 

The author discusses competition between cattle and horses 
in the open range and notes that although horses eat more, 
they are more mobile and therefore do less harm to the range, 
Horses that have difficulty surviving through the winter 
are generally those that have been worked during the summer 
and have not had the chance to build up body resources like 
the year-round feral horses. The author feels that more 
research is necessary, that certain branding practices be 
initiated, and that culling of herds be done when necessary. 

Tseregmid, D. and A. Dashdor j . 1973. Wild horses and other 

endangered wildlife in Mongolia. Trans, by Hon. I. Montagu. 
Oryx. 12(3): 361-370. (DPL) 

"Until the middle of the present century Mongolia was little 
affected by man, in the sense of interference with and dis- 
tortion of the natural environment. In 1918 the population 
of this 600,000 square-mile country was only 640,000, with 
9.6 million domestic animals. (The comparable figures 
today are 1,300,000 and 23.4 million.) Thanks to this lack 
of interference and the protective measures of the Mongolian 
People's Republic, Mongolia still has some of the rarest of 
the world's mammals, notably wild horse and camel, Gobi 
bear and Asian wild ass. The most threatened of them is 
the Przewalski horse, which some scientists think is extinct. 
But the two authors believe that it survives in small numbers, 
They urge the need for large reserved areas where livestock, 
which compete for the horses' grazing and water, can be 

Tyler, Stephanie J. 1972. The behaviour and social organization 
of the New Forest Ponies. A nimal Behavior Monographs . 5(2): 
85-196. (DPL) 

The author spent a total of 3948 hours observing the actions 
and behavior of the New Forest ponies during the years 1965 


to 1968. The New Forest covers an area of 144 square miles 
in Britain of which 103 square miles are under public owner- 
ship. The ponies are believed to be descendants of small 
wild horses indigenous to Britain and are semi-wild; except 
for the annual harvest of young animals and the control of 
stallion numbers they remain free to forage for themselves 
throughout the year. Particular attention was paid to the 
structure and stability of the groups, the dominance- 
subdominance relationships within and between groups, and 
the relationships between mares and their foals. Observa- 
tions were also recorded on the daily maintenance activity 
of the ponies such as grazing, resting, grooming and

"Although many questions are yet to be answered, horses 
seem to establish primary socialization in the first two 
hours after parturition. The foal's bond to its mother 
remains weak relative to the mare's bond to her foal."

"Horses produce a variety of sounds. Among these are 
squeals, nickers, whinnies, groans, blows, snorts, snores, 
and sounds associated with coughing, chewing, flatus, hoof 
beats, and sheath movements. Many, if not all, could act 
in information transfer between horses and facilitate social 
interactions. Furthermore because of the symbiotic relation- 
ship between man and horse, the sounds of the horse function 
at times in inter-species communication aiding in transfer to 
a human handler information about the emotions of the horse, 
thus facilitating the symbiotic relationship." 



Anonymous. 1958. Abandoned horses on the federal range. Our 
Public Lands . 8(2) :3, 12. (DPL) 

The origin of wild horse herds prior to the Taylor Grazing 
Act of 1934 started with their introduction by the Spanish. 
Later after their numbers were depleted in World War I, 
because many were rounded up for cavalry use, their numbers 
grew again as ranchers turned them loose because power 
equipment had replaced many of their functions. The wild 
bands competed with licensed livestock and game animals for 
forage. "The only way these horses can be controlled is 
through organized roundups, conducted under the abandoned 
and estray animal statutes of the states." The article 
goes on to describe different methods of rounding up wild 
horses. Concern for the extinction of wild horses has 
prompted some people to suggest that refuges for them be 
established. The Bureau of Land Management points out that 
this might not be practical because they are constantly 
moving long distances in search of food and forage and they 
might still compete with other forms of wildlife and domestic 
stock. The Bureau feels that if extinction of the wild 
horse were a possibility, some form of public protection 
would be given them.

The article opens with a description of a present-day 
airborne roundup. The author goes on to discuss the loca- 
tions of the remaining wild horse population and the prob- 
lems they are faced with such as fences, sheepherders and 
cattlemen. The article closes with a summary of the history 
of the wild horse in this country. 


Anonymous. 1971. The fight to save wild horses. Time . 12 July 
48-51. (DPL) 

Recent roundups of mustangs are discussed giving the tech- 
niques used. Photographs accompany the text. Recent efforts 
of Mrs. Velma Johnston ("Wild Horse Annie") have resulted 
in legislation being passed. But the article points out 
that ranchers have found a loophole in the law and by re- 
leasing their branded horses among the wild horses they are 
allowed to round up the entire mixed herd. New legislation 
in Congress would outlaw such capture techniques and would 
provide much tougher protection for the wild horses.

Anonymous. 1974. The mustang hunters. Newswee k. 22 April- 78 

The article discusses several problems that have arisen be- 
cause of the 1971 Wild Horse and Burro Act. A 20 percent 
increase in wild horse population is said to be the result 
of protection afforded by the 1971 Act and is cited as having 
angered cattlemen because their cattle must compete with the 
horses for forage. Another problem is that ranchers are 
rounding up wild horses to sell using part of the Act which 
allows owners of stray horses on public lands to recapture 

Amaral, Anthony. 1965. The wild horse of Nevada. Nevada High - 
ways and Parks . Spring: 16-21. (DPL) 

According to the author the population of wild horses in 
Nevada fifty years ago was 100,000. Today, the author says 
that Nevada is the only state that has herds of wild horses 
that are remainders of these large herds. Mus tanging as a 
sport and famous mustangers are discussed followed by a 
general history of wild horses in this country and a recent 
history of wild horses in Nevada.

Melvin Jones, a rancher in eastern Nevada has been capturing 
and converting mustangs into useful cow horses for some years. 
One of his Cinderella horses was Smartie--who was captured 
from a wild herd in central Nevada and rose to become champion 
reined cow horse in the Olympics of that contest at the Cow 
Palace in 1952. Mr. Jones describes how he brings a mustang 
along from wild horse to completed reining horse.

London. 89 p. (DPL) 

A popularized book dealing with wild horses in Canada, 
covering the introduction of the horse to the western world 
in the fifteenth and sixteenth centuries and the use of the 
horses by Indians and cowboys. The Sable Island Refuge is 
discussed in detail. Several interesting aspects of the Sable 
Island horses are that they are less than 14.2 hands high 
and the herds remain in one or two valleys for their entire 
lifetime. The common herd size is a stallion with six mares 
and foals. More than one stallion per herd is common in the 
winter months. The legal means for rounding up wild horses 
in Alberta are outlined.

Gorman, John A. and Gaydell M. Collier. 1972. Free as. ..the 
wind. National Wildlife . October, November : 46-48. (DPL) 

The article discusses wild horses and says they are neither 
livestock nor wildlife, but feral; that is, domestic animals 
which have reverted to the wild. Mustangs are small, tough 
animals, standing between 13 and 14 hands high and weighing 
about 900 pounds. The early history of the horse in North 
America and the impact of the Taylor Grazing Act are dis- 
cussed. The Nevada preserve for wild horses and the Pryor 
Mountain Wild Horse Range are the only two areas where these 
horses are protected. Many of the steps made towards the 
protection of wild horses have been through the efforts of 
Mrs. Velma Johnston ("Wild Horse Annie").

The author raises the question of the feral U. S. wild horse 
designation. He suggests that there may have been horses 
here before the Spanish arrived with their horses . He con- 
cludes that the present wild horse population is descended 
not only from feral animals but also from native horses. 


King, Chuck. 1971. A realistic look at the mustang - wild 
horse situation. Western Horseman . 36(5):44-45, 156, 158. 

The author states that the original mustangs came from 
domesticated horses turned wild and that it is unrealistic 
to try to trace any of the wild horses of today directly 
back to the stock brought to this country by the Spaniards. 
To support this conclusion the author discusses horse ranch- 
ing and breeding illustrating how horses were bred and as a 
result how there could be no pure-blooded Spanish horses 
left in the wild. A need for present-day preserves for the 
wild horses is discussed.

The author, who spent many years running wild horses in 
Wyoming, comments on the Wild Horse and Burro Act of 1971. 
He predicts that the law will allow herds to multiply at a 
very fast rate and that the result will be starvation as a 
means of population control. He also cites problems of 
inbreeding resulting in poorer and poorer horse specimens 
because of the pairing of undesirable recessive genes. A 
need for research is stressed.

A general distribution map shows where the majority of wild 
horses were found at the time of the author's study. He 
says that they run in small herds of from five to fifteen in 
remote back country. They are described as runty, big- 
headed and coarse with agility and stamina. They do not 
significantly compete with other fauna and their only natural 
predator is man. The author expects their numbers to 
dwindle to several thousand.

plants as a basis of range production. Part three discusses 
improvement and management, natural and artificial reseeding, 
control of noxious woody plants, selection and control of 
the various kinds of livestock, standards of range use, 
range inventories and management plans , economics and 
physical and social aspects . The fourth and final part 
considers the protection of the land resources and range 
livestock, including timber reproduction, the use of 
shade trees and shelter belts, stock-poisoning range plants, 
foraging and predatory wildlife on the range, soil erosion 
and control and the general administrations of the public 
lands. Extensive references throughout.

A valuable account of wild horses as they were known to the 
author in 1841. The South American wild horses are 90% bay 
and 10% zains in color. Their only predators are the puma 
and jaguar. If a carnivorous animal is detected by a wild 
horse herd they crowd together and then the stallions rush 
forward to trample him to death. The wild horses of the 
Western United States congregate in thousands because of the 
great abundance of food. These herds belong exclusively to 
the prairie, avoiding mountains and woods.

is a small and scrubby physical appearance. The efforts of 
Mrs. Velma Johnston ("Wild Horse Annie") to prevent motorized 
vehicles from being used to round up horses have resulted in 
Federal legislation forbidding their use. The author recom- 
mends the establishment of wild horse refuges and thinning 
herds on these refuges as necessary.

Range Management . 3rd ed. McGraw-Hill, New York. 532 p. (DPL) 

"Defining the science of range management and presenting the 
principles that are basic to the management of range land 
ecosystems, this text has become a classic in its field. 
The new edition now includes worldwide examples. Rangeland 
resources are identified, and important principles in the 
fields of plant physiology, ecology, economics, and animal 
nutrition are related to the management of range lands. The 
authors discuss multiple uses of rangeland, including 


wildlife, water, forestry and soil stability. Principles 
and practices of manipulating vegetation are presented, 
including both chemical manipulation and biological controls 

Thomson, David. 1972. One final fight for America's wild 
horses. True; The Man's Magazine . February: 27-29, 33, 
82-85. (DPL) 

The author investigates wild horses in the Douglas Mountain 
area of Colorado. He interviews two veteran ranchers in the 
area who feel that the new federal law will cause them hard- 
ship because of the multiple use concept of sharing leased 
land with wild bands of horses . According to one of "the 
ranchers , if the law means that ranchers would lose their 
grazing permits then there is a possibility that ranchers 
would shoot the horses whereas in the past they protected 
them because they could occasionally catch them and sell 
them to ranchers. An historical account of the wild horses 
and the author's first-hand account of seeing wild horses 
in the Douglas Mountain area conclude the article. 

Trueblood, Ted. 1975. Disaster on the western range. Field and 
Stream . 79(9): 14, 22-23. (DPL) 

The author feels that the Wild Horse and Burro Act of 1971 
needs to be amended to give range managers adequate means 
to control these animals. If not amended the author points 
to the following five results which will ensue: extermina- 
tion of two endangered species; the Sonoran pronghorn and 
the desert bighorn sheep; devastation of forage plants 
essential to both domestic livestock and big game; damage to 
watersheds; bankrupting of ranchers; and eventual decimation 
by starvation and disease of the horses and burros themselves. 
In light of this the author goes along with the recommendation 
of the majority of the members of the Wild Horse Advisory 
Board that aircraft be used to control the growing numbers 
of horses. Examples of substantial increases in horse popu- 
lations are cited as reasons for allowing the administrators 
of the range, i.e. the Bureau of Land Management and Forest 
Service, more control over the numbers in the herds.

Wood, Nancy. 1969. The wild horses — heritage or pest? 
Audubon . November: 46-51. (DPL) 

The article discusses why cattlemen and Bureau of Land 
Management officials find wild horses free loaders in federal 
and private lands . Horses produce no profit like big game 
do, therefore it is most expedient to get rid of them. The 
435,000-acre wild horse preserve on Nellis Air Force Base in 
Nevada and the Pryor Mountain Preserve along the Montana- 
Wyoming border are the two areas where horses are protected. 
The total number of wild horses remaining in the U. S. is 
estimated to be 17,300 by the Bureau of Land Management. 
The early history of horse roundups by western cattlemen, 
roundups during World War I, and roundups in the 1920' s are 
outlined. The population of wild horses in 1925 was said 
to have been one million and by 1930 it was estimated that 
the population had dropped to around 100,000. 



Clark, L. H. 1966. They Sang for Horses : The Impact of the 
Horse on Navajo and Apache Folklore . University of Arizona

A small illustrated folio volume exploring the impact of the 
horse on Navajo and Apache folklore. Very soon after the 
horse was introduced to the Navajos and Apaches in the early 
part of the seventeenth century it quickly became the main 
source of wealth among these primitive peoples and exercised 
a dominant influence over their cultures . This dominant 
economic influence naturally became infused with the regional 
folklore. Discussion of Indian veterinary efforts with 
horses and of their equine husbandry. The work contains 
color reproductions of illustrations made by famous Indian 
artists .

A former Indian scout recalls his experiences with wild 
horses as well as Indian knowledge which was passed on to 
him. He describes the horses of 1870 and 1880: "the average 
weight was about 800 pounds, the colors that predominated 
among them were cream, buckskin, or mouse -co lor, they had a 
few black stripes about the legs above the knees, or hocks, 
and a black stripe along the middle of the back, extending 
from the mane to the tail, the stallions did not have a 
shaggy appearance." A predator of the weakened animals and 
colts was the wolf. Early capture techniques are mentioned.

Heritage . 15(2): 16-21, 78-81. (DPL) 

The author outlines the two theories on how the Indian got 
the horse. The earliest theory was that horses lost from 
early Spanish expeditions had, by natural increase, stocked 
the western ranges with wild bands that supplied the various 
Indian tribes with their animals. The more recent theory, 
based on historical evidence, is that the Indians gradually 
got horses from the Spanish and later from each other and 
not from free -roaming bands.

Early maps of the West detail where wild horses were once 
found. The name Wild Horse was applied to springs, mountains, 
canyons , flats , lakes , points , ridges , creeks and mesas . 
The early relationships of horses to settlers and Indians 
are documented by the writings and experiences of early 
explorers such as Pete Barnum, a famed mustanger who caught 
more than 15,000 mustangs between 1904 and 1914 and was the 
inventor of the circular canvas horse trap. The article 
closes with a discussion of current legislation that has been

"This is a carefully documented account of the Indian pony, 
that hardy little animal which, despite its "hang -dog" 
appearance and apparent lack of intelligence, possessed an 
almost unbelievable speed and endurance which allowed its 
rider to run down the fastest buffaloes in the herd or leave 
his cavalryman pursuer far behind. It is also the story of 
the American Indian and his relation to this animal which 
broadened his horizons and developed his abilities as horse 
master and selective breeder, even though he had previously 
known only the dog as a domesticated creature. But more 
than this, it is a historical comment on one of the most 
turbulent and fascinating eras of American frontier history." 

Schuessler, Raymond. 1970. When the Indian got the horse! Horse 
World. 37(11) :66-67, 137-138. (DPL) 

Some contemporaries considered the American Indian among the 
world's best horsemen, led by the Sioux and Comanche tribes. 
The author examines the many ways in which possession of the 
horse changed the social structure of the Indian culture. He 


quotes reports from the Spanish and from Indian tribes . 
The remarkable stamina of these horses and the Indian methods 
of horse training are discussed. These ranged from riding 
out the bucks to very gradual gentling methods. 

Smith, Bradley. 1969. The Horse in the West . World Publishing 
Company, New York. 255 p. (DPL) 

The author, a photographer for "Life" and other magazines, 
has chosen four breeds to represent the horse in the West: 
Arabian, Thoroughbred, Quarter Horse, and Appaloosa. He 
gives a separate section to each breed, covering history, 
legend, development of the breed in the West, qualities and 
conformation, and a modern view that concentrates on a few 
ranches and breeding farms. Each block of text is followed 
by a picture essay of the breed with color photographs show- 
ing the breeds of today. The book also includes a history 
of Western horses since the time of Columbus, picture essays 
on the horse in art and the wild horse of the Pryor Mountains, 
Wyoming, and a map showing the spread of the horse through 
the West.

A discussion of the relation of the European horse to the 
culture of the Plains Indians . A general resume of the 
literature at hand provides approximate dates of horse intro- 
duction into various tribes and is followed by a comprehensive 
section on the means through which the Indians acquired the 
horse. The author covers tribal customs and habits and 
their relation to the introduction of the horse. An example 
of this is the migration habits of tribes before and after 
the horse became a part of their culture. Thoroughly 

Worcester, D. E. 1944. The spread of Spanish horses in the 

Southwest. New Mexico Historical Review . 19:225-232. (DPL) 

This article expounds the generally accepted theory that the 
Plains Indians did not acquire horses through strays being 
lost by Spanish expeditions, as has been suggested by some 
writers, but rather that Spanish ranches supplied both the 
horses and the horsemanship to the Indians of the Southwest. 
There is nothing to suggest that there were mounted Indians 
in the Southwest before the 17th century, nor any reason to 


believe that the natives of that region learned to use 
horses except from the Spaniards. Well documented. 

Worcester, D. E. 1945. Spanish horses among the Plains tribes. 
Pacific Historical Review . 14:409-417. (DPL) 

This article theorizes that the northward spread of the use 
of horses was from tribe to tribe and man to man rather than 
capture from roaming herds. It is possible that wild horses 
may have entered some sections of the Plains in advance of 
the knowledge of horsemanship, but there is no evidence of 
any tribe learning to use horses except from horsemen of 
other nations. The Indians acquired considerable knowledge 
of horsemanship and knew which horses to use for war expedi- 
tions based on hoof features. 

Wyman, Walder D. 1945. The Wild Horse of the West . Caxton 
Printers, Caldwell, Idaho. 348 p. (DPL) 

This book places primary emphasis on events since 1890, but 
goes back to the original introduction of horses by the 
Spanish. It maintains that distribution of horses to Indians 
was primarily by means of northward movement of Spanish 
strays. It details the influence of horses on Indians and 
stockmen up to the present time.

State Senator Beilenson of California introduced a bill pro- 
hibiting exploitation of threatened wildlife, which he recently 
amended to include wild horses. The bill was introduced to 
discourage the practice of trapping and killing Nevada 
mustangs for commercial purposes. Importation of wild 
horses to California slaughter houses is now against the law.

The Colorado House Agriculture Committee voted unanimously 
to indefinitely postpone action on a wild horse protection 
bill that had passed overwhelmingly in the Senate. As a 
result the year-round open season on wild horses remains in 
effect. The early history of the horse in the new world is 
mentioned, including early capture techniques such as creasing, 
which meant shooting the horse in the withers, which would 
stun him until he could be roped. The recent decline of the 
wild horse is discussed along with the efforts of Mrs. Velma 
Johnston ("Wild Horse Annie"), to save them for future 
generations .

The article discusses the Wild Horse and Burro Act of 1971. 
According to the Act, November 15, 1974 was the last date 
private citizens could claim wild horses. They now all 
belong to the United States. The Bureau of Land Management 
is now authorized to take a census of the herds in given 
localities and to allocate each herd enough land to sustain 
it. Ranchers are distressed because in some cases they must 
now share leased federal land with wild horses and they are 
forbidden to round up wild horses to sell to rendering plants

A discussion of why the Wild Horse and Burro Act of 1971 was 
passed overwhelmingly and why wild horses have claimed so 
much recent attention and publicity. The history of the horse 
starting with the Spanish is chronicled to its gradual dis- 
appearance in the 20th century. The efforts of Mrs. Velma 
Johnston ("Wild Horse Annie") are outlined. The author calls 
attention to the necessity for a serious study of wild horse 
habits. He claims that wild horse refuges or reserves, several 
of which have been established in recent years, are only a 
partial solution to the problem.

Pontrelli, M. J. 1969. Protection for wild mustangs. Defenders 
of Wildlife News . October, November, December : 444 -446 . (DPL) 

Senator Frank E. Moss introduced a bill (S-2166) concerning 
the protection and preservation of wild horses, specifically 


the Spanish Barb and the Andalusian. The bill, if passed, 
would place these horses on the endangered species list. All 
wild horses would then be rounded up and the Barb and 
Andalusian would be separated out to be preserved in pro- 
tected areas; the remaining wild horses would be separated 
out and disposed of. Dr. Pontrelli finds the following 
problem with this proposed legislation: "since all horses 
are to be rounded up and since most evidence points to the 
fact that no pure blooded Barb and Andalusians are in the 
wild, then a strict interpretation of the bill would call 
for the virtual elimination of all wild horses." He goes on 
to outline the points he feels are important for legislation 
concerned with the protection and preservation of wild 
horses .

tion of the Wild Free-Roaming Horse and Burro Act, Public 
Law 92-195 . 58 p., appendices. (DPL, USDA, USDI) 

The report fulfills section 10 of public law 92-195, The 
Wild Free-Roaming Horse and Burro Act. The review presents 
the progress made and the problems encountered by these two 
agencies in their administration of wild horses and burros. 
It also contains considerations for legislative changes which 
will assist the agencies in meeting the intent of the 1971 Act 
in a more effective, humane, and cost -conscious manner. Two 
amendments to the 1971 Act are being considered. The first 
amendment would permit the use of aircraft or other motorized 
vehicles to be used for the protection, management, and con- 
trol of wild horses and burros . The use of such equipment 
would be in accordance with humane procedures prescribed by 
the two secretaries . The second amendment would authorize 
the two secretaries to sell or donate excess animals to 
private individuals or organizations. Extensive appendices. 



Cook, C. Wayne. 1975. Wild horses and burros: a new management 
problem. Rangeman's Journal . 2(1): 19-21. (DPL) 

The author was Chairman of the National Advisory Board for 
Wild Free -Roaming Horses and Burros and has been on the Board 
since it was formed after the passage in 1971 of the Wild 
Horse and Burro Act. In this article Dr. Cook gives a brief 
description of the wild horses, their early numbers and con- 
trol, their management and recent population figures, and 
finally their present control under the Wild Horse and Burro 
Act. The main focus of the article is on the inadequacy of 
the present federal legislation, namely the 1971 act and how 
it needs to be changed. Dr. Cook suggests several changes. 
He suggests that the Wild Horse and Burro Act be amended to 
include provision for control and to allow aircraft, if 
necessary, , to implement this control. The ownership of 
horses and burros should be transferable to individuals and 
the law should be amended to provide for the complete re- 
moval of horses and burros from certain areas and the estab- 
lishment of ranges where they can be managed appropriately. 

Dudley, Aaron. 1970. Nevadans ponder plight of wild horses. 
Western Livestock Journal . 49(3) :1+. (DPL) 

A confrontation occurred between those concerned with the 
future of the wild horse and members of the Nevada State 
Cattlemen's Association and Nevada Wool Growers at their 
combined convention, held in Winnemucca, Nevada, in 
November. Stockmen suggested that the horses supposed to 
be wild are simply those turned out and owned by ranchers. 
Mrs. Velma Johnston ("Wild Horse Annie"), known for her 
protective efforts, defined a wild horse as those "one 
generation removed from the domestic animal and. . .unclaimed.' 
She was joined in her efforts by the President of the Nevada 
chapter of the National Mustang Association, Newcastle, 
Utah. Academic support came from an assistant professor of 
biology, Dr. Michael Pontrelli, at the University of Nevada 
who, together with his students, had been collecting field 
data on the mustangs for several years. Ranchers expressed 
their lack of understanding over public concern for 9,000 
"worthless" mustangs and state game officials explained that 
they did not fall under the heading of wildlife. Lack of 
management was seen as the chief cause of the mustang prob- 
lems, but no one present knew from what source management 
funds would come. 


Hall, Ron. 1972. Wild Horse: Biology and Alternatives for 
Management, Pryor Mountain Wild Horse Range . Bureau of 
Land Management, Billings District. 67 p. (DEL) 

"Population dynamics, distribution and behavior data were 
collected on the horse herd in the Pryor Mountains, Montana. 
Population data were collected by aging and sexing 124 
horses. Additional sex data were collected by using a 
spotting scope. Distribution and behavior information was 
collected through observations for one year. Distribution 
of the horses is dictated by water, forage and weather con- 
ditions. The horses have seasonal home ranges but do not 
establish territories. Home ranges vary in size with the 
size being dependent upon available forage. Breeding season 
seems to be a function of the green-up which brings mares 
into heat. Average harem group is three to four (3.4) 
animals. Range trend has been sharply downward for several 
years. Management will consist of population control and 
proper distribution. Distribution will be accomplished 
by water manipulation and/or feeding." 

Hall, Ron. 1974. Wild horse capture techniques . Bureau of 
Land Management. 24 p., illus. Draft. (DPL) 

The author discusses and accompanies with illustrations the 
following capture techniques: water, dry, holding facilities, 
drug immobilization, and roping. The author concludes by 
saying, "regardless of the technique used, the manager must 
have intimate knowledge of the behavior of the horses on 
the terrain in which they live. The manager must use all 
the ingenuity at his disposal to humanely capture horses 
while attempting to keep costs within fundable levels."

The decisions of the National Wild Horse and Burro Advisory- 
Board made at the Reno, Nevada 1974 meeting are discussed. 
To deal with the increasing populations, the Board's plan 
was as follows: "A series of 'intensive management units' 
(or wild horse refuges) would be established throughout 
representative ranges in the West, with the exact number yet 
unknown but possibly varying between 10 and 20. The remainder 
of the wild horse and burro populations not in the designated 
management areas would then be removed from the balance of 
the public domain." Vehicles such as helicopters would have 
to be used to round up the left-over horses and burros and 
those not claimed would be sold to defray the cost of rounding 
them up. This plan is in conflict with existing legislation.

The author discusses a roundup of 70,000 Nevada wild horses 
in 1950, a roundup which he believes was the last massive 
roundup of feral horses in the United States. Current legi- 
slation is discussed as ineffective because there is little 
authority given to make sure it is enforced. The mustang of 
today is not the tough, hot-blooded descendent of the Spanish 
horse; those mustangs disappeared before the turn of the 
century. Today's wild horse is a mixture of many things, 
made up of a conglomeration of eastern breeds from Europe, 
along with Spanish and North African blood. A great number 
of the "American" horses came from ranchers and farmers who 
released them onto the prairie. The author recommends that 
the government be periodically allowed to round up excess 
horses „

The Indians rounded up horses in 1946 and sold them to finance 
sports and other activities of the all-Indian American Legion 
Post there. The horses were forced from their home range to 
confuse them and due to their being in strange new surround- 
ings and flustered with excitement, they became tired. In 
this panicked condition they were easy to capture and herd 
into corrals. Local Indian reservation and forestry officials 
estimate that there were more than 5,000 wild horses roaming 
over the Fort Simcoe and Medicine Valley areas.

wild horse "massacre" which occurred in February, 1973. 
According to the American Horse Protection Association the 
"hunt" violated two federal laws and an Idaho State anti- 
cruelty law. Bureau of Land Management negligence concerning 
the enforcement of the two federal laws was claimed by 


several wild horse organizations. The author points out that 
the federal laws are inadequate because there is no provision 
for the acquisition of funds to carry out and enforce the 
laws. There is a thorough discussion of problems brought 
about by the Taylor Grazing Act of 1934 and its relationship 
to the use of "National Resource Lands."

The savage and proud wild horses of America who toiled 
dutifully when domesticated and literally pulled and carried 
America to prosperity, have gradually declined in numbers since 
the turn of the century. The mustangs at one time numbered

In 1968 controversy arose concerning the outcome of a 200- 
head herd of wild horses in the Pryor Mountains on the 
Mont ana- Wyoming border. The Bureau of Land Management, 
concerned about worsening rank's conditions in the area, 
suggested these alternatives: maintaining the greatest 
number of horses, maintaining fewer horses to further 
reduce competition with deer, and remove all the horses 
and manage the area for wildlife. Finally a 32,000-acre 
Pryor Mountain Wild Horse Range was established in 1968 
and a citizen's advisory committee was appointed to study 
the range and make recommendations to the Bureau of Land 
Management for future management. The committee's recom- 
mendations are included.

As early as 1950, photographer Verne Wood started promoting 
a plan for a state-controlled refuge for wild horses in 
Wyoming. He used his wild horse pictures for publicity. 
The proposed refuge would be controlled by fish and game 
wardens, and "some four hundred head would be permitted to 
live without danger of being rounded up by professional 
horse-hunters." The author goes on to describe the aspects 
of the horse roundups. He maintains that the refuge would
