Threats [top]

Major Threat(s): The major threats are: deforestation due to agricultural development, cultivation of illegal crops, logging, and human settlement; introduction of alien predatory fish in streams; and pollution resulting from the spraying of illegal crops. It occurs in the international pet trade, but it is not known to what extent this poses a threat to the species. Chytridiomycosis might be a potential future threat.

Conservation Actions [top]

Conservation Actions: It occurs in Parque Nacional Natural Farallones de Cali. Management practices that could allow a commercial, sustainable harvest of this species should be investigated. Decree INDERENA No. 39 of 9 July, 1985, forbids the collection of Phyllobates spp. from the wild in Colombia for breeding (or other) purposes. It is listed on CITES Appendix II.
