Rank ReasonsCastilleja rubida is restricted to high elevations in the Wallowa Mountains of northeastern Oregon. It is abundant where it occurs; however, it is threatened by recently introduced mountain goats that trample plants and degrade the habitat.
Range Extent CommentsCastilleja rubida occurs in the western United States where it is restricted to high elevations in the Wallowa Mountains of northeastern Oregon. Range extent was estimated using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1993 and 2024 (CPNH2024, iNaturalist 2024, NatureServe 2024, SEINet 2024). One historic specimen from the Hurricane Creek drainage was not included due to the ephemeral nature of the population. Additional specimens collected outside of the Wallowa Mountains are mislabeled collections of other taxa (M. Egger, pers. comm., 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are six occurrences rangewide (CPNH 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsCastilleja rubida is threatened by introduced mountain goats and climate change (OBIC 2019, NatureServe 2024).
Ecology & Habitat
