Protection Sought for Four Vulnerable Plantsįour species of plants were proposed by the Fish and Wildlife Wildlife Service Endangered Species Program, Washington, D.C. Technical Bulletin Department of interior. Historically, this rodent was distributed over approximately 2,000 square miles (527,600 hectares) from southern Merced County, through the San (continued on page 9) 1 ENDANGERED SPECIES TECHNICAL BULLETIN Vol. The giant kangaroo rat's preferred habi- tat consists of native dry grasslands with well-drained, sandy-loam soils suitable for digging burrows. Widespread modification of its south-central California habitat has elimi- nated this species from 94 percent of its former range the remaining habitat also is vulnerable. Several taxa are listed as Endan- gered, and the Fish and Wildlife Service (FWS) has proposed listing another, D. Giant Kangaroo Rat Proposed for Addition to Endangered Species List giant kangaroo rat (Dipodomys ingens) Kangaroo rats of the genus Dipodomys are small mammals adapted for swift travel by hopping on their elongated hind legs. There has been debate among bota- nists as to the taxonomic distinction be- (continued on page 8) Iliamna corei (Peter's Mountain mallow) is a perennial growing 20-36 inches (0.5-0.9 meters) tall with large flowers that are rose or light pink in color. For this reason, the FWS did not propose designating Critical Habitat for this species, an action that would pinpoint the site by the required publication of maps and detailed geographical informa- tion nevertheless, if it is listed, the plant will receive habitat protection. Any further collecting could be extremely detri- mental. Some individuals and seeds of this attractive plant also have been taken for planting in home gardens. corei, as many botanists have visited the site since its discovery in 1927 to collect herbarium specimens. Scientific collecting also has been a problem for /. corei colony and destroyed a number of plants directly. This trail, now abandoned, was built through the I. How the leafcup be- came established there is open to specu- lation, but its spread may have been ex- pedited by habitat disturbances associated with the completion of a nearby power transmission line or the construction of a hiking trail. Although growth of the for- est canopy has been a factor, the primary threat is competition from an introduced herbaceous species, the Canadian leaf- cup (Polymnia canadensis), which now dominates the site. corei appear to be the main reasons for the population's reduced numbers and its decline in repro- ductive vigor. The encroachment of competing vege- tation and the subsequent reduction in di- rect sunlight reaching I. They received full sunlight and produced "an abundant supply of seeds." In July 1984, however, observers counted only 5 plants (consisting of 55 stems) at the site. Earl Core discovered the species in 1927, there were about 50 plants growing vigor- ously in the soil-filled pockets of an ex- posed sandstone outcrop. The single population occurs on private land near the summit of Peter's Mountain in western Virginia (Giles County). Iliamna core/ This perennial plant gets its common name, Peter's Mountain mallow, from the only site at which it is found. If the propos- als become final, these plants and their habitats will receive the protection author- ized under the Endangered Species Act. All four have experienced declines in their ranges and numbers, primarily as a result of human-related habitat loss. 20240 Protection Sought for Four Vulnerable Plants Four species of plants were proposed by the Fish and Wildlife Sen/ice (FWS) re- cently for listing as Endangered.
