Present Legal or Other Formal Status: Agoseris lackschewitzii 

 currently has no status under the Endangered Species Act but is 

 on the Sensitive list for Region 1 of the U.S. Forest Service. It 

 is currently ranked by the Montana Natural Heritage Program 

 globally as G3 (either rare and local or locally in a restricted 

 range, 21-100 occurrences) and in Montana as S2 (imperiled 

 because of rarity, 6-20 occurrences) . The state rank is currently 

 under review because of many new locations reported from the 1991 

 field season; it will likely be revised to S3. In addition, a 

 population of this species was found in the Banff National Park, 

 Alberta area in 1991 (Achuff 1992) and thus, the global ranking 

 may also need to be revised. 



Geographic Distribution: Agoseris lackschewitzii is currently 

 known from 27 locations in eight counties of central and 

 southwestern Montana (Cascade, Deer Lodge, Judith Basin, Madison, 

 Meagher, Park, Silverbow, Sweetgrass) and two counties in 

 southcentral Idaho (Fremont, Lemhi) . A disjunct occurrence is 

 also known from the Sunshine Meadows area of western Banff 

 National Park, Alberta and adjacent British Columbia. 



Habitat and Associated Species: Agoseris lackschewitzii occurs 

 primarily in moist herbaceous meadows and in the ecotone between 

 moist meadows and forest. Associated species in Montana include: 



Androsace septentrional is fairy candelabra 



Antennaria alpina alpine pussytoes 



Arnica mollis hairy arnica 



Caltha leptosepala elkslip

Population Biology and Ecology: Populations of Agoseris 

 lackschewitzii are generally small, ranging from 15-100 plants. 

 Flowering is generally in July and August. Reproduction is 

 primarily by seed with some vegetative reproduction by splitting 

 of the caudices.
