Scientific Name:	Dendropsophus gryllatus
Species Authority:	(Duellman, 1973)
Taxonomic Notes:	This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Dendropsophus (Faivovich et al. 2005).

Assessment Information [top]

Red List Category & Criteria:	Endangered B1ab(iii) ver 3.1
Year Published:	2004
Assessor/s:	Luis A. Coloma, Santiago Ron, Diego Cisneros-Heredia, Ana Almendáriz
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Contributor/s:
Justification: Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in the Pacific lowlands of northwestern Ecuador.

Geographic Range [top]

Range Description:	This species is known from the Pacific lowlands of north-western Ecuador, from 200-500m asl. It is known from three localities, but with further sampling is likely to occur more widely.
Countries:	Native: Ecuador

Population [top]

Population:	It is a rare species.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This is originally a lowland forest species. However, specimens have been collected at a large duckweed-covered pond in a banana plantation outside forest; a few individuals were calling from bushes at the edge of the water, while others were found on grasses overhanging shallow muddy pools (Duellman 1973). It breeds in ponds, and probably deposits its eggs in the water.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The main threat to this species is habitat loss, and much of the natural vegetation within its range has been cleared. While its occurrence in banana plantations may suggest that the species can survive in altered habitats, farming practices have changed radically over the last 20 years, especially with the use of pesticides, and cultivation that is more intensive. The soil is very fertile, and banana plantations do very well; however, these plantations are increasingly intensively managed and the use of pesticides poses an increasing threat.
