From the IUCN Red List Species Account:

 

Range Description

This species occurs in Sierra de Omoa and Espíritu Santo in northwestern Honduras and in Sierra Caral in northeastern Guatemala, between 40 and 1,570 m asl. Its extent of occurrence (EOO) is estimated to be 3,746 km

Habitat and Ecology

It is found on low vegetation along streams in lowland moist forest, and premontane and lower montane wet forest. It is only found in relatively undisturbed forest habitat (C. Vásquez-Almazán pers. comm. 2014). Breeding and larval development take place in streams.

Population

The species is relatively common along streams and rivers at sites where it occurs (C. Vásquez-Almazán pers. comm. 2014); however, there is some evidence of possible past declines (Townsend et al. 2006). The species is restricted to remnant forest habitat throughout its range, and there is lack of habitat connectivity between known locations attributed to the inhospitable nature of the surrounding agricultural matrix; therefore, it is assumed that the population is severely fragmented (C. Vásquez-Almazán pers. comm. 2014). 

Population Trend

Unknown

Major Threats

The main threat to the species is habitat loss due to agriculture (for uses such as pasture), wood extraction, and water pollution. A large subpopulation resides in Cusuco National Park, but it became apparent that habitat destruction is beginning to encroach within the park (Townsend et al. 2006). Several individuals were found less than one kilometre away from an area being cleared for agriculture (J. E. Kolby pers. comm. 2008). Use of agrochemicals and illegal logging by communities within and around the Sierra Caral protected area may also represent threats to this species (C. Vásquez-Almazán pers. comm. 2014). Chytrid infection has recently been confirmed in this species (39.6% prevalence; Kolby et al. 2010). Droughts and flooding are also considered possible threats (C. Vásquez-Almazán pers. comm. 2014).

Conservation Actions

In Honduras, it is known to occur in Parque Nacional Cusuco and in Parque Nacional Cerro Azul, both formally protected since 1987. It also occurs in the recently established (2012) Sierra Caral reserve in Guatemala. Surveys are required to monitor the population status and trends of this species, particularly given the threat of chytridiomycosis. Management strategies are needed to eliminate illegal deforestation that has occurred in some protected areas and to prioritize restoration activities that could restore habitat connectivity.
