RIO GRANDE NATIONAL FOREST, COLORADO
Along the headwaters of the Rio Grande del Norte, “ Great River
of the North,” lies a rugged country favored with an abundance of
natural wealth. Many stockmen are dependent upon it for summer
range. Farmers know it to be the source from which flow the waters
that make the San Luis Valley a prosperous community. Tourists
call it scenic. Fishermen know it as a place for a sure catch. And
foresters are managing there a valuable stand of timber. Such is
the Rio Grande National Forest, risen to fmportance out of the ashes
of one of Colorado’s early mining flares. When “It was day all day

in the daytime and there was no night in Creede” the rich yields of
ore and the business of mining held men’s attention to the exclusion
of all else, but a pause in the-production of minerals has revealed
other wealth.

The Rio Grande National Forest is a storehouse of great natural
wealth. It is an important economic factor in the welfare of sur-
rounding local communities. It is a public asset in which everyone
of its users should have a personal interest.

Timber production and watershed protection are of first im-
portance in the administration of the forest, but management of
grazing lands and the development of the recreational resources are
also important. Recreational uses are free, except where permits for
summer homes or lodges are desired. A charge is made for permits
for summer homes and other special uses, for grazing privileges, and
for timber.
Of the annual income derived from the forest 35 per cent is spent —
locally—25 per cent through a cash fund returned to the counties —
within the forest for roads and schools, and 10 per cent through the —
development by the Forest Service of roads and trails within the —
forest. In addition, community development is furthered by the

large amounts spent from the regular Federal forest road appropri-
ation for the building of roads within and adjacent to the forest for
the purpose of making the natural resources more accessible and
improving the means of forest protection.
THE TIMBER CROP
The Rio Grande National Forest may be regarded as a large
diversified farm, the main products of which are ‘timber and forage
crops.
The annual crop of timber is represented by the total annual growth
of all the trees, or growing stock. In any one year the crop is taken
from only a part of the forest. Each part of the forest is cut over
in turn and is then left to accumulate a new crop. Operations are
confined to the cutting of ripe or mature trees, and the weeding out of
he ae

those that are overmature, diseased, or defective. This leaves a
stand of thrifty immature trees, the basic growing stock, free from
competition and in a condition favorable for increased growth, the
production of seed, and the perpetuation of the stand.
The annual growth of timber at this time amounts to about 20,000,-
000 board feet, and an annual crop equal to that amount can be

however, does not warrant harvesting any considerable part of the

the stump,” where it will be safe from decay for many years.

TREES OF THE RIO GRANDE?
Tree growth on the Rio Grande Forest is of two general types:
Coniferous or evergreen, and broadleaf or deciduous.

CONIFERS
PINES
The four kinds of pines found on the Rio Grande Forest always
have long, needle-shaped leaves in clusters of from two to five. The
cones are woody and hang from the limbs.
Western yellow pine—wWestern yellow pine is found at lower elevations.
Leaves 3 to 5 inches long, deep green, usually two in a cluster but often in
threes, and in tufts at the ends of the branches. Cones 3 to 5 inches long, oval;
usually found near end of branches. Cone scales armed with spines.
Limber pine.—Limber pine is sometimes erroneously called pifion or nut
pine. Found in foothills and also in rocky places in high mountains. Leaves
dark green, always in clusters of five, 144 to 3 inches long. Cones 3 to 5 inches
long, with seeds about one-third inch in length. Cone scales smooth. Bark
light gray or silvery white, except on old trunks, which are blackish brown.
Pinon.—Piion pine is confined to the foothills. Needles three-fourths to 1%
inches long, in clusters of two and rarely of three. Cones 1144 inches long and
almost as broad. Seeds are the common pifion nuts of trade.
Bristlecone pine.—Bristlecone pine is found at higher elevations, usually ©
close to timber line. Needles 1 to 2 inches long, always in clusters of five, and
covered with tiny specks of pitch. Cones 3 to 4 inches long with the scales
armed with a slender bristle.
SPRUCES
Spruces are of two kinds. Both have short, square, single leaves,
which easily roll between the fingers. Crowns have a whitish or
aa cast. Cones are not woody but fibrous and hang from the
ranches.
Engelmann spruce.—The small branches of Engelmann spruce are covered
with soft, short hairs. Leaves less rigid and sharply pointed than those of
blue spruce; dark biue, green, or pale steel blue. Cones 1 to 2 inches long.
Bark is dark, reddish brown, and separates in the form of small rounded
scales.
Blue spruce.—The small branches of blue spruce are always smooth. Leaves
stiff and with sharp points. The blue spruce can be told from Engelmann spruce
by grasping the tip of a branch and noting the spinelike stiff leaves. Cones
2 to 3 inches long. Bark on old trunk gray, divided lengthwise into ridges.
FIRS
Firs are of two kinds.
Alpine fir—Alpine fir has flat leaves, 1 to 13%, inches long, without any stem
where they join branches. Cones standing straight up on branches, 2% to 4
inches long, dark purple. In the fall the cones fall to pieces and leave only a
spike on the branch.
White fir—wWhite fir is found at the lower elevations with western yellow
pine and Douglas fir. Leaves single, flat, 2 to 3 inches long, soft. Cones 3 to 5
inches long, standing straight up on branches. Bark on old trees 5 to 6 inches
thick, deeply divided into broad, rounded ridges broken on the surface into
irregularly shaped platelike scales.
JUNIPERS OR CEDARS
Junipers or cedars are of two kinds, one a small tree and the other
a shrub. Seed in berries, not cones.
Rocky Mountain red cedar.—Rocky Mountain red cedar has scale-like pointed
leaves, very small, that cover the slender, four-sided twigs in four rows .of alter-
nately opposite pairs; stiff branches. Mature berries one-fourth inch in
diameter, bluish or black, covered with a whitish bloom.
Dwarf juniper—Dwarf juniper is always a shrub, 1 to 3 feet high. Leaves
in groups of three, spearate on branches, sharp pointed. Branches not stiff.

DOUGLAS FIR
There is one kind only of Douglas fir. It has flat leaves, three-
quarters to 114 inches long, apparently with a short stem joining
them to branches. The cones hang down on long, stout stems, 2 to
4 inches long, with 3-pronged bracts protruding from between the
cone scales.
BROADLEAF TREES
ASPEN
Aspen has flat, nearly heart-shaped leaves about 2 inches across that tremble
characteristically in a breeze. Bark whitish or very pale green, smooth with
black scars where branches have dropped off. Trees rarely more than 20 feet
high. (Commonly called quaking aspen or quaking asp locally.)
NARROW-LEAF COTTONWOOD
Narrow-leaf cottonwood is usually a tall tree, 40 to 60 feet high. Bark dark
gray, heavily ridged half or two-thirds of the way up the tree; above that
smooth, pale green. Leaves one-fourth to one-half inch wide by 2 to 3 inches
long, very similar to willow leaves.

Fic. 5.—Excellent summer range for San Luis Valley herds bs
ALDER
Alder is found along and overhanging the streams, usually in clumps, several
trees growing from the same root, frequently 4 to 6 inches in diameter and
15 to 25 feet high. Leaves large and sharply double-toothed. Matured seed-
bearing fruit noticeable in winter.
THE FORAGE CROP
Grasses and weeds suitable for forage are found in many of the
timber stands and in the parks and large open areas above timber
line. Wild game has always roamed over these natural pastures, but
they require only a small part of the available growth. The bulk of
the forage is available for domestic stock.
The grazing of livestock is, in general, a secondary use on the
national forests, but at this time it is the largest activity on the Rio

Grande. The 220,000 head of sheep and cattle with their offspring
which are supported by the forage of this national forest represent
an investment of nearly $5,000,000. This is in addition to the in-
vestment in ranch property required for carrying on the livestock
business.
The efficient handling of the summer range is in itself a large ©
enterprise. The range must be used to the fullest extent, and at
the same time its future capacity must not be endangered by
overgrazing. Neither must grazing be allowed to injure forest
reproduction.
The time of grazing and the number of stock using the range must
be limited in order to insure ample feed during unfavorable as well
as favorable years. Stock should not be turned on the range until

Fic. 6.—A contented herd on luxuriant summer feed
the forage plants have had a chance to get “set,” and the number
of stock should be kept down so that from 10 to 20 per cent of the
palatable species will be left to mature and produce seed.
Experiments in range management are carried on constantly by
the Forest Service, and improved methods are applied as fast as they
are proved worth while and can be put into operation. Because
of the limited amount of national-forest range it is very important
that the utmost care be given to its use and protection.
GAME
Deer, elk, mountain sheep, bear, lion, bobcats, blue and willow
grouse, ptarmigan, duck, and many other kinds of game range on
the Rio Grande. It is the policy of the Forest Service in handling
the grazing of domestic livestock and all other uses of the forest to
reserve adequate range for these wild animals, many of which are a
distinct asset in mountain country. The game naturally use parts
of the forest which can not be used efficiently for domestic stock.
Furthermore, the relatively small amount of wild game which now
RIO GRANDE NATIONAL FOREST, COLORADO 9
remains makes the conflict with domestic stock practically negligible.
The killing off of lions and bobcats, as well as individual outlaw
bears, is encouraged. State laws give limited protection to deer,
Fic. 8.—Under protection elk are increasing rapidly
grouse, ducks, and other game, permitting hunting only during a
specified open season. Elk and mountain sheep are protected the
year around. No hunting is permitted without a State license.

WATERSHED PROTECTION
Watershed protection is one of the primary purposes for which the
national forests are maintained. Irrigation is the keystone of the
prosperity of the San Luis Valley, and most of the water for this
purpose comes from the Rio Grande National Forest. In addition,
the welfare of a large territory in southwestern United States and
northern Mexico depends upon the waters of the Rio Grande, and
the effects of overgrazing, fire, or destructive logging along the
headwaters of this river, all of which are within the Rio Grande Na-
tional Forest, would be felt far beyond the limits of the forest. Using
only so much timber and forage as is grown each year helps to estab-
lish and maintain on the forest those conditions necessary to prevent
erosion on the watershed.

The Wheeler National Monument, a grotesquely eroded geological
feature within the Rio Grande Forest, has been set aside by presi-

States Engineers.
Ages ago lava outpourings piled up at this spot and the elements
have worn them into figures of exceptional beauty. The monument
may be reached by a trip of 12 miles over a Forest Service trail.
Saddle horses may be hired at Creede, and the trail leads across
the face of Mammoth Mountain (11,042 feet), giving a superb view
of the upper Rio Grande country and of Creede with its adjacent
mining activities.

which can not be prevented. But the Federal Government and local
men and women can not trail careless tourists in order to make the
forests safe.
INFORMATION
The headquarters of the Rio Grande National Forest is in Monte
Vista, Colo., and additional information or assistance may be ob-
tained by writing the forest supervisor there or by getting in touch
with one of the forest rangers, who are located at various points
throughout the forest.

5. Zodets——Use public toilets where available. They are properly
located. Toilets should be at least 100 feet from streams and not in
gulches.
6. Obeying laws.—Observe rules and endeavor to have others do
the same. National and State laws impose heavy penalties for health-
law violations. Report all violations or insanitary conditions (in-
cluding dead animals) to the nearest health officer or United States
Forest Service officer.

SIX RULES FOR PREVENTION OF FOREST FIRES
1. Matches—Be sure your match is out. Break it in two before
you throw it away.
2. Tobacco.—Be certain that pipe ashes and cigar or cigarette
stubs are dead before throwing them away. Never throw them into
_ brush, leaves, or needles.
3. Making camp.—Before building a fire scrape away all inflam-
_ mable material from a spot 5 feet in diameter. Dig a hole in the
center and in it build your camp fire. Keep it small. Never build a
_ fire against trees or logs or near brush.
_ 4, Breaking camp.—Never break camp until your fire is out—dead
out.
— 5. Brush burning—Never burn slash or brush in windy weather
or while there is the shghtest danger that the fire will get away.
6. How to put out a camp fire-—Stir the coals while soaking them
with water. Turn small sticks and drench both sides. Wet the
ground around the fire. Be sure the last spark is dead.
