snowbed whitlow-grass
Draba crassifolia
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Snowbed whitlow-grass faces severe threats from climate change as warming temperatures reduce snowpack duration and alter the timing of snowmelt in its high-altitude habitats. The species' specialized adaptation to snowbed environments makes it particularly vulnerable to shifts in snow cover patterns, which directly affect soil moisture and growing season length. Habitat fragmentation from infrastructure development and recreational activities in alpine areas further isolates already small populations, reducing genetic diversity and limiting natural dispersal.
Habitat
Snowbed whitlow-grass occupies specialized alpine and subalpine snowbed habitats, typically found in areas where snow persists late into the growing season. The species thrives in moist, well-drained soils that remain saturated from snowmelt, often growing in rocky crevices and scree slopes at high elevations.
