Population Trend


Major Threats

Disturbance, and any kind of alteration of forested areas that might cause the desiccation of streams and soils, are threats to this species.

Conservation Actions

This species occurs in at least two protected areas. Urgent protection of the forested areas along the Sierra Tarahumara area is recommended.

Red List Status

Near Threatened (NT)


Listed as Near Threatened since the species depends on streams in pristine forest, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat in the Sierra Madre Occidental in Mexico is declining, thus making the species close to qualifying for Vulnerable.
