. . dedicated to the appreciation and conservation of the Colorado native flora” Volume 18 Number 1 January/February 1 994 The Dwarf Milkweed — An Endangered Species? Jim Locklear Dyck Arboretum of the Plains I wish I could report that we now have a complete understanding of the biology and conservation needs of the dwarf milkweed, Asclepias uncialis. Unfortunately, while we continue to learn more about this plant, it remains one of the most enigmatic species in the flora of Colorado and the great Plains. What we do know about A. uncialis suggests that it should be seriously considered for protection as an endangered species. I first became aware of Asclepias uncialis while scanning the treatment of the genus, Asclepias, by Dr. Ron Hartman in the Flora of the Great Plains. One rather cryptic statement about this plant grabbed my attention — “This species is either rare or overlooked.” Since then, this little milkweed has been something of an obsession with me. The first time I looked for it was in 1989, searching (with no success) historical localities in Baca and Cheyenne counties in eastern Colorado. In 1990, with funding from The Nature Conservancy and the Colorado Native Plant Society , I spentabout ten days searching in northeast New Mexico and southeast Colorado and succeeded in 'finding populations in Union County, New Mexico and in Las Animas and Pueblo counties in Colorado (steAquilegiaVol. 15 No.2). Two years later, in 1992, the Colorado Native Plant Society again graciously funded several days of field work, this time in northeast Colorado, resulting in the discovery of a single population in Kit Carson County (see Aquilegia Vol. 16 No. 4). In addition to this field work, I have done an extensive search of herbarium collections for A. uncialis specimens. Forty-seven herbaria in North America and Europe were consulted. Altogether, it appears that 37 separate collections of A. uncialis have been made (including my own) over a 144- year period, representing approximately 29 different localities. Nineteen of these localities are in eastern Colorado, three in northeast New Mexico, three in southwest New Mexico, three in Arizona, and one in southwest Wyoming. One current gap in our understanding of A. uncialis is the relationship between plants within the main area of distribution (eastern Colorado and northeast New Mexico) and the collections from Arizona, southwest New Mexico, and Wyoming. Taken together, these occurrences present a rather far-flung area of distribution for such an apparently rare species. The Wyoming occurrence is a collection made by the famous botanist, Charles C Parry, in 1873 near the Green River in the south westpart of the state. Parry’s collection is baffling since it was made about 250 miles away from the nearest known occurrence of A. uncialis in the Great Plains (Weld County, Colorado). Dr. Robert Dorn searched for A. uncialis in 1993 in the vicinity of Parry’s collection site, but was unable to find it. The other problematic collections come from Arizona and southwest New Mexico. There is some question as to whether these - continued on page 4 Contents Membership Information 2 Dues Reminder 2 Announcements 3 U.S.F.W.S.

Presentations will focus on research and management from an ecosystem point of view, and will include such topics as fire ecology, planning in mountain communities, and riparian restoration. Agendas will be available by late February. For more information, call Nan Lederer at 447-1899. Life in an Aspen Grove, an educational program prepared by the CONPS Education Committee, is now available in slide/cassette or videotape formats. This introductory - level program takes a close look at aspen trees, the rich and varied habitat they create, and some of the many species that make their home in aspen woodlands for all or part of their yearly cycle. The viewer is encouraged to think about the relationships between various components of this familiar Colorado ecosystem. The program includes 80 color slides depicting plant and animal life associated with aspen groves. A cassette tape (with audible advance signals) contains the spoken narrative. Alternatively, the program is available as a 27 -minute videotape. A printed booklet containing the narrative, an extended text containing additional details, and a glossary of terms is included. See page 11 for ordering information, or call Miriam Denham (303) 442-1020 for ^more information. co. * 4 ^ Aquilegia is printed on 100% recycled paper ERRATA The article entitled Is The Endangered Species Act In Danger? that appeared in the last issue of Aquilegia (Vol. 17 No. 3) contained the following errors: * 1.

This question will probably not be resolved without thorough biosystematic studies. Unfortunately, the material required for such comparative studies will be difficult to obtain from the southwestern occurrences. Of the three known Arizona occurrences, two are quite old (collected 78 and 90 years ago, respectively) and have not been relocated. The other, collected in 1990, consisted of only two individual plants and, despite careful search by the botanist who discovered the population, no plants could be found at the site in 1991, 1992, or 1993. One of the most interesting developments in the saga of Asclepias uncialis has been the rediscovery of this species in southwest New Mexico. Edward L. Greene discovered the plant he named Asclepias uncialis near SilverCity, New Mexico in 1880. It was collected again at Silver City in 1919 by Alice Eastwood, who deposited specimens in several major herbaria. It would be another 73 years, however, before this plant was collected again in southwest New Mexico. In 1992 Dr. Dale Zimmerman, Professor Emeritus of Biology at Western New Mexico University, located a single A. uncialis plant growing in a patch of ungrazed blue grama (Bouteloua gracilis = Chondrosumgracile) grassland about three miles north of Silver City. As if this weren’t exciting enough, a few days later Dr. Zimmerman received a phone call from a friend asking him to identify an unusual low milkweed growing in his backyard in Silver City. To his utter disbelief, Dr. Zimmerman found two more individuals growing in the middle of town on his friend’s quarter-acre yucca-grassland remnant! Dr. Zimmerman has had a long-standing interest in finding plant species described by EdwardL. Greene while he resided in the Silver City area during the 1880’s, and A. uncialis was one of the species he had been keeping an eye out for. Y et, in over 30 years of botanizing in the region, he had not succeeded in finding the plant until 1992. Dr. Zimmerman did quite a bit of additional searching after finding these two “populations,” but no other individuals, much less populations, were found. In a recent conversation, he reported to me that the two plants in the Silver City backyard are doing fine, but he has been unable to relocate the other one-plant population north of town. While there is a need for clarification of the relationship between plants within the main distribution of A. uncialis on the plains and these more distantoccurrences, two facts remain clear: Small as it is, however, the Kit Carson County population presently stands as the world’s largest; all other recently known extant populations of A. uncialis consist of only one to nine individuals. As has been the case in other Great Plains localities where A. uncialis has been found Asclepias uncialis Artist: Carolyn Crawford A. uncialis has been collected very rarely in the last 50 years and, where it has been found recently, it occurs in exceedingly tiny populations. This observation is reinforced by my experience in northeast Colorado in 1992. I set out to relocate two historical collection sites and to search other potential habitat for this species. After five days of field work, I succeeded in finding only one population consisting of 14 individual plants. This population, located along the South Fork of the Republican River in KitCarson County, was found only after hours of painstaking search in the area. And, while acres of apparently suitable habitat were available, the 14 plants occurred together in an area only about one square meter in size. in recent years, there was nothing particularly notable about this species’ habitat in Kit Carson County. The surrounding vegetation was shortgrass prairie dominated by blue grama. Typical of other occurrences, the plants in KitCarson County were growing primarily in small areas of bare soil between patches of blud grama. - continued on page 5 Number 1 Aquilegia Page 5 MILKWEED, continued from page 4 The only aspect of this species’ ecology on the plains that appears to be characteristic is its tendency to occur on gently sloping ground below rimrock or rock outcroppings, such as at the base of a mesa escarpment. The population in Kit Carson County occurred on a slope below low bluffs of the Ogallala formation. A collection made by Dr. William Weber in Prowers County in 1991 occurred in similar habitat, described as “below rimrock ridges.” The pattern presented by the distribution of historical collections and the present demography of A. uncialis is that of a once more common species, now represented by scattered, remnant, possibly declining populations. One-third of the known collections of this species were made in the 1800’s, suggesting thatA. uncialis was more common in the past than it is today. This deduction is supported by the fact that several of the early collections are represented by a number of duplicate herbarium sheets, some of which display several individual plants. As an example, Elihu Hall and J. P. Harbour distributed seven different herbarium sheets from their 1862 collection of A. uncialis from “Great Plains, Lat. 41.” In another case, one of the five herbarium sheets distributed by Alice Eastwood from her collections at Silver City in 1919 displays six individual plants — an impressive population by today’s standards! About 60% of the known collections of this plant were made before 1950 and it appears that it was rare even then; C. M. Rogers, who collected A. uncialis in Las Animas County, Colorado and in adjacent Union County, New Mexico in 1948, listed this species as “infrequent to rare” in his description of the vegetation of the Mesa de Maya region. While our knowledge of this species is still rather limited, Asclepias uncialis appears to warrant serious consideration for protection as an endangered species. Although it has a rather large geographic distribution, only eight recently verified populations of this species are known to exist. These populations consist of only two to 14 individual plants each. Furthermore, all known populations are quite isolated from one another. Rarity of known occurrences and exceedingly small population size are warning signs that this species may be teetering on the brink of extinction. Since the majority of the historical collections of A. uncialis are from eastern Colorado, both amateur and professional botanists in the state have an opportunity to help clarify the conservation needs of this plant. Collections during the past few years have confirmed the presence of A. uncialis in Fremont, Kit Carson, Las Animas, Prowers, and Pueblo counties. However, historical collection sites in Baca, Bent, Cheyenne, Denver, Huerfano, Otero, Sedgewick, Washington, and Weld counties remain to be relocated and searched. As the name implies, the dwarf milkweed is a tiny plant and can be quite difficult to find in the field. This situation should be aided, however, by a wonderful illustration prepared recently by Carolyn Crawford. Carolyn’s drawing is based on herbarium specimens and photographs, and is an excellent representation. If you’re out in the field in April or early May and find a two-inch-tall milkweed with rose-purple flowers that looks just like Carolyn’s drawing, then congratulations! You’ve Cutbacks Affect U.S. Fish & Wildlife Service Region 2 Office Regional U.S. Fish and Wildlife Service offices are experiencing some “downsizing” as a result of funding cutbacks. Approximately 30 people from offices in Denver, Grand Junction, the Dakotas and Nebraska are being relocated or laid off. This will affect a variety of endangered species programs. Funding is being diverted toward regions, such as the Pacific Northwest, with more visible endangered species problems. Of particular interest from the CONPS perspective is that Lucy Jordan, botanist at the Colorado office in Grand Junction, has decided to return to the Salt Lake City office and will be leaving her Colorado position January 21st. Lucy has been a focal point for botanical efforts in Colorado and surrounding areas. She has been instrumental in coordinating the Rare Plant Technical Committee, which brings botanists from several government agencies, academia, the private sector, and interested groups, like CONPS. Her presence will be missed. The good news is that Lee Carlson, supervisor of the Colorado Field Office, intends to hire another botanist or plant specialist to fill the vacant position, perhaps as soon as this spring. For the sake of plant conservation here in Colorado, we hope he is able to fill the position very soon! Page 6 Aquilegia Volume 18 Colorado Native Flora and The Public Lands Grazing Reform Debate Tim Hogan Conservation Committee The issue of public lands grazing has moved onto the front pages of many Colorado papers in recent months. It started this autumn with a filibuster by Western Senators, including Hank Brown and Ben Nighthorse Campbell, over an attempt by the Department of the Interior to raise grazing fees on public lands. The coverage has continued, as a series of meetings called by Secretary Bruce Babbitt have taken place across the state in an attempt to resolve this contentious issue. Unfortunately, there has been a lack of insight with which the media have been covering the discussion of grazing on public lands. The coverage has focused on economics and an adversarial scenario in which ranchers’ culture and livelihood are threatened by elite urban preservationists who don’t eat beef. There has been little attention paid to the fundamental reason that public land grazing is opposed by many in the environmental community. The reason is not a balanced budget or an antipathy for ranchers, but rather the indisputable evidence of what cattle and sheep have done to the native ecosystems of western North America. The ecological integrity of countless mountain meadows, dry uplands, and riparian zones has been devastated by poorly managed livestock grazing over the last century. Natural communities and native species have been altered or extirpated from portions of their ranges. Predators have been trapped, shot, and burned. A great silence hangs over a world that was once rich in its diversity of plants and animals. The reason the ranching industry is being asked to reform its practices on public lands is because it has acted without individual or collective restraint. The General Accounting Office (the investigative arm of Congress) has issued a series of reports on public lands grazing and its effects on land and wildlife. The G.A.O. found that public lands were overgrazed (1989), that cattle were given preference overwildlife(1989, 1991), that there was no land management (1990), and that grazing of excess numbers of livestock was common (1990). The 1991 report documented conditions so bad that the G.A.O. recommended Congress halting allU vestock grazing on 20 million acres of arid lands in five states. A 1990 document from the Environmental Protection Agency discloses that riparian areas in the West are in the “worst condition in history,” while the G.A.O. reports that grazing is a principle agent in the degradation of Western riparian areas. This is not surprising given the fact that 2,500 gallons of water are required for each pound of beef produced in the arid and semi-arid West. The ecological degradation is all the more senseless considering that 260 million acres of public land — an area equivalent in size to the combined eastern seaboard states, from Maine to Florida — are open to grazing, yet these lands produce less than 3 percent of all U.S. beef. The State of Vermont raises more beef than Nevada! more ranchers sit in the state legislature than lawyers, the governor grew up on a ranch, three out of eight state Wildlife Commissioners are ranchers , and one of our two federal senators is a rancher. Members of the Colorado Native Plant Society are in a good position to lend their shoulder to the wheel of change that is attempting to reform grazing policies on our public lands. There are few of our members who have not witnessed first hand the effect that cattle and sheep have had upon our native flora. From the alpine meadows of the San Juans to the grasslands of the Pawnee, we have bemoaned the impact of livestock as we have explored Colorado on Society field trips and on our personal excursions. It is essential that we inform ourselves about the issue, persuade our representatives to support the protection of native plant and animal diversity, write letters to our local papers, and use our botanical expertise to offer testimony at public hearings. It is important to remember that the subject of reform addresses public lands: lands that are held in trust for all Americans. Grazing interests have argued that changes will threaten the livelihood of small ranchers, yet the largest permit holders, the top 10 percent, control about half of the nation’s public grazing lands, according to Interior Department figures. Only 12 percent of the permit holders are listed by the government as small operators. Among the largest permitees are the Metropolitan Life Insurance Company, the Mormon Church, the Zenchiku Corporation (a Japanese conglomerate) and Hewlett Packard. While an increase in grazing fees is necessary, it is only one step toward a thorough reform of the way our public lands are managed. The recent events in the Senate have demonstrated the deep entrenchment of livestock interests. In Colorado, where less than one-tenth of one percent of the population holds a public lands grazing permit, almost every county commission has at least one rancher member, Far too often, the effect of cattle and sheep on the ecosystems of western North America has been one of compromise, loss, and ruin. Aldo Leopold said that to see with the eyes of an ecologist is to “live in a world of wounds.” It is important that the abuses to which our public lands have been subjected are stopped, and that aprogram of restoration is initiated that will begin the healing of these wounds. f What You Can Do V An environmental impact statement and a new set of draft regulations for public lands grazing is due out in early March.

Sally White Conservation Committee In April 1993, the U.S. Fish and Wildlife Service listed the Florida lichen, Cladonia perforata, as endangered. This appears to be the first listing of a lichen, and thus represents a distinctive step in plant conservation. Cladonia perforata, distantly related to the more familiar reindeer moss (i Cladina ), is a conspicuous fruticose lichen that forms large dense clusters as much as 2.5 inches tall, according to the listing notice (Federal Register 25746, 27 April 1993). Lichens in this family (Cladoniaceae) are probably the most commonly collected lichens, and even have economic value, being used as miniature shrubbery in architectural models and model railroading, not to mention serving as forage for the world's reindeer, co i^& The Florida perforate cladonia was listed along with six other plant species that occur in dry upland vegetation (scrub, high pine, and turkey oak barrens) of central peninsular Florida. This habitat type is a xeromorphic shrub community dominated by evergreen or nearly evergreen oaks and/or Florida rosemary, sometimes with a pine overstory. It occupies well drained, infertile, sandy soils. “Loss of habitat, primarily to citrus groves and residential development, is the primary threat to these species,” according to the listing notice. The majority of this habitat type was converted to citrus groves many years ago. Thirteen otherplants, two lizards, and the Florida scrub jay have been listed as threatened or endangered due to loss of this type of habitat; several additional plants remain on the candidate list for possible listing. What lessons does such a faraway action ( anchave for local conservation? I think there W^are several; Ecosystem approaches The listing of seven species from the same habitat in a single package is efficient. This approach could expedite action on plants (e.g., the alpine plant, Eutrema penlandii, which was recently listed as threatened, may occur with other species that are similarly threatened by restricted distribution in an abused environment, yet it languished in a backlog of species in need of attention and protection). In these days of agency cutbacks (see page 5), we would do well to encourage and assist such time- and species- saving habitat oriented listing proposals. Don’t be too shy Clearly, other conservationists are not daunted by the prospect of promoting listing of a lowly, unglamorous plant that may not easily sway public opinion. If the data supporting population declines and threats are there , this action demonstrates that listing is possible — even for a lichen. Cladonia perforata has an estimated population size of “only” 26,000 individuals at 12 sites, several of which are already protected or proposed for protection. Opponents of the Eutrema listing argued with the U.S. Fish and Wildlife Service and listing supporters over whether there were 5 ,000+ or 16,000+ individuals! Either figure is too low! Good solid legwork A massive survey of Florida lichens in the 1960s and subsequent studies included searches of 84 “rosemary balds” at the Archibald Biological Station; C. perforata was found at only seven of them. Extensive searches confirmed a total of 12 sites, and another recently destroyed site, but no new sites. Few lichens have enjoyed so much attention. Persistence pays off In 1989, one researcher petitioned the U.S. Fish and Wildlife Service to list C. perforata. The Service found listing “warranted but precluded by work on other species having higher priority.” The finding was repeated in 1 99 1 .

WANTED PLANT LISTS This notice appeared in the American Society of Plant Taxonomists (ASPT) Newsletter 7(3): 10-1 1 in July, 1993. Colorado Native Plant Society members are likely to be particularly good sources for the type of species lists requested by researchers in Oklahoma and V er mont. If you have plant species lists from botanical field trips or projects, you may be interested in helping these researchers. Pass the word along to others who might be interested. As part of a project to quantitatively compare vascular floras in North America north of MEXICO, information is sought on floras of regions smaller than states (i.e., parks, forests, nature preserves, research areas, islands, counties, individual bogs, mountains, etc.). The ultimate goal of this research is to devise a method to estimate the size of floras, and the degree of completeness in a species list. In order to do this, the researchers need to see as many vascular floras as possible. They currently have information from ca. 1000 floras, but suspect that there are many times this number. A side benefit of their research will be a bibliography of North American vascular floras. Unfortunately, vascular floras frequently are published in obscure places and are thus difficult to find. The researchers would appreciate information that would help them locate additional floras. They are particularly interested in learning about floras in obscure journals, proceedings of state or regional academies of science, government documents, theses, dissertations, privately published lists, and unpublished lists. They would appreciate entire lists in the form of reprints or photocopies, but any sort of bibliographic data is welcome.
