Powell's Chernes

Allochernes powelli

Unknown

Overview

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

Powell's Chernes faces severe habitat degradation from urban development and agricultural expansion across its limited range in California. The species' dependence on specific microhabitat conditions within oak woodlands makes it particularly vulnerable to fragmentation and edge effects. Climate change poses an additional threat through altered moisture regimes that could disrupt the delicate bark and leaf litter environments essential for this pseudoscorpion's survival.

Threat summary

Habitat

Powell's Chernes inhabits the bark crevices and leaf litter of oak woodlands in California, requiring specific moisture and temperature conditions within these microhabitats. The species is particularly associated with mature oak trees that provide stable bark environments and accumulated organic matter beneath the canopy.
