Hispaniolan Pink-rumped Frog

Eleutherodactylus paulsoni

Declining

Overview

Eleutherodactylus paulsoni is a species of frog in the family Eleutherodactylidae. It is endemic to the Tiburon Peninsula, Haiti. It is a terrestrial frog. It is typically found in association with caves or creek beds located in closed forest, from sea level to 750 m (2,460 ft) asl. Habitat loss caused by logging and agriculture is threat to this species. It is known from the Pic Macaya National Park, but habitat degradation is occurring in the park too.

Eleutherodactylus paulsoni faces severe threats from habitat destruction due to urban development and agricultural expansion across its extremely limited range in Puerto Rico. The species' small population size makes it particularly vulnerable to stochastic events and environmental changes. Introduced predators and competitors, along with potential disease outbreaks, pose additional risks to the remaining populations of this endemic frog.
