Overview

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

The Bolson tortoise faces severe population decline primarily due to extensive cattle ranching and agricultural conversion throughout its limited range in the Chihuahuan Desert. Overgrazing by livestock degrades the native grassland habitat essential for the species' survival, while direct collection for the pet trade has historically reduced wild populations. Climate change poses an additional threat through increased drought frequency and temperature extremes in an already arid environment.

Threat summary

Habitat

The Bolson tortoise inhabits desert grasslands and scrublands in the Chihuahuan Desert of north-central Mexico, preferring areas with sandy soils and scattered shrub vegetation. This species requires open grassland areas for foraging and suitable soil conditions for constructing the extensive burrow systems that provide shelter from extreme temperatures.

The Bolson tortoise faces severe population decline primarily due to extensive cattle ranching and agricultural conversion throughout its limited range in the Chihuahuan Desert. Overgrazing by livestock degrades the native grassland habitat essential for the species' survival, while direct collection for the pet trade has historically reduced wild populations. Climate change poses an additional threat through increased drought frequency and temperature extremes in an already arid environment.
