From the IUCN Red List Species Account:

 

Range Description

This species is known from Antioquia to Valle del Cauca Departments on the western flank of the Cordillera Occidental, Colombia, between 1,100–2,000 m asl. It occurs in four threat-defined locations, and its EOO is 7,496 km2.

Habitat and Ecology

This species is found on low vegetation alongside streams in primary and secondary cloud and rainforest forests. It can tolerate some habitat destruction as long as vegetation remains alongside the stream. Eggs are laid on the top of leaves above the stream and, when hatched, the larvae drop into the stream below where they then develop further.

Population

It was previously thought to be a common species, however updated information now suggests that it is uncommon. The last known specimen collected was before 2010, and several recent surveys between 2014–2016 to the southern part of its distribution did not yield any records (W. Bolívar pers. comm. March 2017). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Major Threats

The major threat to this species is habitat loss and degradation due to smallholder farming and subsistence logging, illegal mining, water pollution from the spraying of illegal crops, and mining activities (W. Bolívar pers. comm. March 2017).

Conservation Actions

Conservation Actions
The range of the species includes several protected areas, however there is no information about specimens collected in any protected area (W. Bolívar pers. comm. March 2017).

Research Needed
Taxonomic research is needed to determine whether or not this represents a complex of species. Research into population trends, threats, ecology and distribution are also recommended for the species (W. Bolívar pers. comm. March 2017).

Red List Status

Vulnerable (VU)

Rationale

Listed as Vulnerable because its extent of occurrence (EOO) is 7,496 km2, it occurs in four threat-defined locations, and there is continuing decline in the extent and quality of its habitat on the Western Cordillera of the Colombian Andes.

Taxonomic Notes

This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Hyloscirtus (Faivovich et al. 2005). This form might represent a species complex.
