Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits dry, scrubby forest with scattered terrestrial bromeliads at the type locality and humid montane forest in the Rio Zaña Valley. Individuals of this species were observed in terrestrial and arboreal bromeliads or calling from rock ledges and low vegetation at night (Duellman and Lehr 2009). This species presumably breeds by direct development.
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): Four of the five known localities are within the Udima Wildlife Refuge. Threats to this species at the type locality are not known, although in general there is regional loss of habitat due to increased agricultural activity and selective wood extraction.
