Monomorium pergandei
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Monomorium pergandei faces severe habitat degradation from urban development and agricultural expansion across its limited range in the southwestern United States. The species is particularly vulnerable to ground disturbance and soil compaction from construction activities, which destroys the specific soil conditions required for nest establishment. Competition from invasive ant species, especially Argentine ants, has displaced native colonies from optimal foraging areas.
Habitat
This species inhabits arid and semi-arid regions of the southwestern United States, typically nesting in sandy or gravelly soils in desert scrublands and grasslands. Colonies are often found in areas with sparse vegetation cover and well-drained substrates that provide suitable conditions for underground nest construction.
