Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Lampsilis higginsii faces severe population declines primarily due to habitat degradation from agricultural runoff, sedimentation, and dam construction that alters natural flow regimes in its river systems. The species' complex reproductive cycle, which requires specific fish hosts for larval development, makes it particularly vulnerable to disruptions in aquatic ecosystems. Water quality deterioration from point and non-point pollution sources has eliminated populations from portions of its historical range across the upper Mississippi River basin.
Habitat
Lampsilis higginsii inhabits medium to large rivers with stable substrates of sand, gravel, and cobble in areas with moderate to swift currents. The species requires clean, well-oxygenated water and is typically found in riffle and run habitats of the upper Mississippi River drainage system.
