Astragalus terminalis G3G4S1 - Watch - 



One population is known from the range on BLM land in Limekiln 

 Canyon. The species occurs in grasslands and sagebrush 

 grasslands, usually in soils derived from limestone. 

 Additional populations in the Tendoys are most likely to occur 

 on BLM land but may also occur at lower elevations on the 

 Beaverhead National Forest. It is most likely to be found on 

 the eastern flank of the range (Red Rock Creek drainage). 

 Plants flower in June and produce fruit in July; they are 

 identifiable in either of these stages. 



Carex parryana ssp. idahoa G2QS2 Sensitive Sensitive 3C 

 Three populations are known on BLM land from the vicinity of 

 the Tendoys, in the Basins of Muddy Creek and upper Big Sheep 

 Creek, and one population is known on state land in the 

 Tendoys at Lower Poison Lake. An additional population is on 

 the Beaverhead National Forest at Morrison Lake in the 

 Beaverhead Mountains. The species occurs in moist floodplain 

 bottoms often in Potentilla fruticosa/Juncus balticus 

 communities, and, at Poison Lake, in a fen. Wetlands are not 

 extensive on USFS land in the Tendoys but the species may be 

 found around springs or along creeks; one potential site which 

 has not been surveyed is Porcupine Spring. The plants produce 

 mature fruit in late July to August. Mature fruit is 

 necessary to key out the species, but it is recognizable, with 

 experience, in earlier stages. 



Carex vallicola G5S2S3 _ _ _ 



One population was found on the Beaverhead National Forest in 



a high elevation sagebrush grassland near Sourdough Spring. 



Additional occurrences should be sought in sagebrush, 



grassland, and aspen communities throughout the Tendoys. This 



sedge produces fruit, needed for reliable identification, in 



July. 



Erigeron asperugineus G4S1 Sensitive - 



This Great Basin species was not found in the Tendoy Mountain 

 study areas, but is known in the Beaverhead National Forest 

 from the Beaverhead Mountains. It grows in open soil and 

 scree in the subalpine and alpine zones. There is some 

 potential for this plant at the higher elevations in the 

 Tendoys. Flowering is in July. 



Eriogonum caespitosum G5S1 _ _ - 



The population on state land in the upper Big Sheep Creek 

 drainage is the only verified occurrence of this species in 

 Montana. Here it grows in dry soil derived from limestone in 

 a low sagebrush (Artemisia arhuscula) community, a vegetation 

 type which is not known on the Beaverhead National Forest in 

 the Tendoys, but it is reported from a variety of arid and 

 rocky community types elsewhere (Dorn 1992, Welsh 1987). The 

 plants flower in July.
