Habitat and Ecology

Habitat and Ecology
The subspecies Ptychohyla euthysanota euthysanota lives in cloud forests while the other subspecies (P. e. macrotympanum) lives in broadleaf forests and pine forests. Both subspecies are highly associated with mountain streams. Reproduction occurs by direct development.

Justification
Listed as Near Threatened because its Extent of Occurrence is probably not much greater than 20,000km2, and the extent and quality of its habitat are declining, thus making the species close to qualifying for Vulnerable.

Threats

Major Threats
A major threat to this species is alteration of the original habitats and microhabitats due to smallholder agricultural activity and logging. Chytridiomycosis is also a potential threat to this species, particularly for high-altitude populations. Declines due to chytridiomycosis amongst species of this genus have already been detected in Guatemala (Mendelson, et al. 2004).

Management

Conservation Actions

Conservation Actions
It occurs in at least two Biosphere Reserves in Chiapas (La Sepultura and El Triunfo) and is listed as "threatened" (Amenazada) by the Mexican government, although improved protection of forest habitats in southern Mexico is needed. It also occurs in Parque Nacional Montecristo in El Salvador, but is not protected in Guatemala. Given the potential threat of chytridiomycosis populations of this species should be monitored closely.
