Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Tylomys bullaris faces severe population decline primarily due to extensive deforestation and habitat fragmentation across its limited range in Central America. Agricultural expansion, particularly cattle ranching and subsistence farming, has eliminated much of the cloud forest habitat this species requires. The species' restricted distribution and specialized habitat requirements make it extremely vulnerable to ongoing forest conversion and climate-induced shifts in montane forest zones.

Threat summary

Habitat

This climbing rat inhabits cloud forests and montane rainforests at elevations between 1,200-2,400 meters in Central America. It requires dense forest canopy with abundant epiphytes and is particularly associated with areas of high humidity and consistent cloud cover.
