Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-01-25

This species is listed as Least Concern in view of its wide distribution, presumed large population, occurrence in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category. Although Least Concern, there is quite a bit of habitat degradation for this species, and its status should be watched as it may become Near Threatened in the near future.

Threats [top]

Major Threat(s): Very intensive agriculture and tourism development are reducing this species' habitat.

Conservation Actions [top]

Conservation Actions: It occurs in protected areas in Guatemala. Research is needed on the taxonomy and basic biology and ecology of this species because very little is known about it.
