Diplocardia zicsii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Diplocardia zicsii faces severe habitat degradation from urban development and agricultural expansion across its limited range in California's Central Valley. The species' specialized soil requirements make it particularly vulnerable to ground disturbance from construction activities and intensive farming practices. Climate change poses an additional threat through altered precipitation patterns that affect soil moisture levels critical for this earthworm's survival.
Habitat
This earthworm species inhabits specific soil types in California's Central Valley, particularly in grassland and oak woodland ecosystems with well-drained, organic-rich soils. The species requires stable soil conditions with adequate moisture retention and minimal chemical contamination.
