Arenaria bolosii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Arenaria bolosii faces severe threats from its extremely restricted range in the Pyrenees, where it occupies only a few high-altitude locations. The species is particularly vulnerable to climate change as warming temperatures force alpine vegetation zones upward, potentially eliminating suitable habitat. Human activities including hiking, mountaineering, and infrastructure development in its limited range pose additional pressures on the remaining populations.
Habitat
This endemic plant species inhabits rocky crevices and scree slopes in high-altitude alpine environments of the Pyrenees mountains. It typically grows in calcareous substrates at elevations above 2,000 meters, where it has adapted to harsh conditions including intense UV radiation, temperature fluctuations, and short growing seasons.
