Borderea chouardii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Borderea chouardii faces severe threats from its extremely restricted range, existing only on limestone cliffs in the Pyrenees with fewer than 12 known populations. The species is highly vulnerable to rock falls, erosion, and extreme weather events that can eliminate entire subpopulations. Climate change poses an additional threat through altered precipitation patterns and temperature extremes that could affect the specialized cliff microhabitats this endemic plant requires.
Habitat
This endemic species occupies vertical limestone cliff faces and rocky crevices in the Pyrenees mountains of France and Spain. It grows exclusively in specialized microhabitats on calcareous rock formations at elevations between 500-1,500 meters.
