From the IUCN Red List Species Account:

 

Range Description

This species occurs along the Pacific border of Chiapas, Mexico, south-east to the Pacific slopes of Guatemala as far as Volcán Atitlán. Its altitudinal range is 1,800-2,500m asl.

Habitat and Ecology

It occurs in montane cloud forest and pine-oak forests, and requires pristine habitat. It is semi-arboreal, but can also be found under bark or under logs. It breeds by direct development and is not dependent upon water.

Population

This species appears to be still relatively common (Carlos Vasquez and Sean Rovito pers. comm. 2007).

Population Trend

decreasing

Major Threats

The main threat to this species is habitat loss following the transformation of forest habitats to agricultural lands and for human settlement. Habitat loss through its range has been quite extensive. When forest is cleared, a close relative, Bolitoglossa lincolni, colonizes the range of, and hybridizes with, Bolitoglossa franklini.

Conservation Actions

It occurs in the Reserva de la Biósfera El Triunfo in Chiapas, which includes some areas that still have pristine habitat. In Guatemala it is found within the protected volcans. It has been recorded from the 'Quetzal Reserve' in Departamento San Marcos, Guatemala (Ted Papenfuss and Sean Rovito pers. comm., 2007). There is a need for improved protection of the forest habitat of this species in the remainder of its range. It is protected by Mexican law under the "Special Protection" category (Pr).

Red List Status

Endangered (EN)

Rationale

Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and in the extent and quality of its habitat in Mexico and Guatemala.

Taxonomic Notes

This taxon might be a complex of several species (Highton, 2000).
