Cambarus cracens

Unknown

Overview

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

Cambarus cracens faces severe threats from habitat degradation due to agricultural runoff and sedimentation in its limited stream systems. Urban development and water extraction have altered natural flow regimes, while pollution from agricultural chemicals has degraded water quality in critical breeding areas. The species' restricted range makes it particularly vulnerable to localized environmental changes and extreme weather events.

Threat summary

Habitat

This freshwater crayfish inhabits clear, cool streams and springs with rocky or gravel substrates in forested watersheds. It requires well-oxygenated water with stable temperatures and minimal sedimentation for successful reproduction and survival.
