Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pogonomyrmex anergismus faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in the southwestern United States. The species' specialized nesting requirements and dependence on specific soil types make it particularly vulnerable to ground disturbance from construction activities. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate moisture balance required for colony survival.
Habitat
This harvester ant species inhabits arid and semi-arid desert scrublands and grasslands of the southwestern United States, particularly favoring areas with well-drained sandy or gravelly soils. The colonies construct distinctive gravel mounds and require specific soil composition and drainage characteristics for successful nest establishment.
