Santamartamys rufodorsalis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Santamartamys rufodorsalis faces severe threats from rapid deforestation and agricultural expansion in the Sierra Nevada de Santa Marta, where its cloud forest habitat is being converted to coffee plantations and cattle ranching. The species' extremely restricted range makes it particularly vulnerable to habitat fragmentation, while climate change threatens to shift suitable temperature and moisture conditions upslope beyond the mountain's peaks. Mining activities and infrastructure development further fragment the remaining forest patches critical for this endemic rodent's survival.
Habitat
This endemic rodent inhabits cloud forests and humid montane forests in the Sierra Nevada de Santa Marta of northern Colombia, typically found at elevations between 2,000-3,000 meters. The species requires dense forest canopy with high humidity levels and specific temperature ranges characteristic of these isolated mountain ecosystems.
