Pisidium johnsoni
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pisidium johnsoni faces severe threats from habitat degradation and water quality deterioration in its limited freshwater environments. Agricultural runoff, urban development, and pollution have significantly impacted the pristine water conditions this species requires. Climate change-induced alterations to precipitation patterns and water temperature further stress remaining populations in their restricted range.
Habitat
This freshwater bivalve inhabits clean, well-oxygenated streams, springs, and small rivers with sandy or gravelly substrates. It requires stable water conditions with minimal pollution and is typically found in areas with consistent water flow and temperature.
