Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Anolis roosevelti faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in Puerto Rico. Hurricane damage has repeatedly devastated the remaining forest fragments where this species persists, with recovery hampered by the gecko's extremely small population size. Introduced predators, particularly cats and rats, pose additional pressure on this ground-dwelling species that has already lost most of its historical habitat.

Threat summary

Habitat

This critically endangered anole inhabits dry coastal forests and scrublands in southwestern Puerto Rico, particularly areas with rocky outcrops and dense vegetation cover. The species requires intact forest canopy and leaf litter for foraging and shelter, making it highly vulnerable to habitat fragmentation.
