Trinomys yonenagae

Declining

Overview

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

Trinomys yonenagae faces severe habitat loss due to agricultural expansion and urban development within its extremely restricted range in Bahia, Brazil. The species' dependence on specific sandy soil formations makes it particularly vulnerable to land conversion, as these unique habitats are increasingly cleared for cattle ranching and crop cultivation. Mining activities and infrastructure development further fragment the remaining suitable habitat patches.

Threat summary

Habitat

This spiny rat is endemic to sandy coastal plains and dune systems in the Caatinga region of Bahia, Brazil. It specifically requires areas with loose, well-drained sandy soils where it can construct its elaborate burrow systems.
