Rank ReasonsPlatanthera yosemitensis was described in 2007 and occurs only in the wet montane meadows of Yosemite National Park (Colwell et al. 2007). It is known from approximately seven populations, four of which have fewer than ten flowering individuals. Additional populations may be found in the central Sierra Nevada. Possible threats include meadow succession, recreational activities, and horticultural collecting (Lazar and Bittman 2007).
Range Extent CommentsPlatanthera yosemitensis is endemic to Yosemite National Park, in Fresno and Mariposa Counties in California, although its range could be larger (Colwell et al. 2007).
Threat Impact CommentsMay be threatened by meadow succession, recreational activities, and horticultural collecting (Lazar and Bittman 2007).
