Threats [top]

Major Threat(s): Although this species does tolerate moderate levels of habitat destruction, wholesale habitat loss caused by agricultural activities is a major threat to the species. Chytridiomycosis is also a major threat, and declines due to the disease have already been detected amongst species of this genus in Guatemala (Mendelson et al. 2004).

Conservation Actions [top]

Conservation Actions: It is not known to occur in any protected areas, and habitat protection is urgently needed. In view of the severe risk of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations might need to be established.
