Eleutherodactylus rucillensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Eleutherodactylus rucillensis faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited montane range. The species' extremely restricted distribution makes it particularly vulnerable to environmental changes, with deforestation and land conversion eliminating critical breeding and foraging areas. Climate change poses an additional threat by altering the temperature and humidity conditions essential for this moisture-dependent amphibian's survival.
Habitat
This species inhabits montane forests and cloud forest environments at elevations between 800-1,200 meters in the mountains of Puerto Rico. It requires humid, well-vegetated areas with adequate leaf litter and moisture retention for breeding and shelter.
