Conservation Status and What It Means for Landowners
Federal Status: Proposed Endangered | State Status: Threatened
Mexican fawnsfoot is Federally proposed endangered and state threatened in Texas. Landowners managing for this species should be aware of applicable legal protections and consult with TPWD regarding management activities that may affect the species or its habitat.
Habitat Requirements
Mexican fawnsfoot (Truncilla cognata) occurs in riverine and stream habitats across 11 Texas counties. Freshwater mussels are sensitive indicators of water quality and stream health. They require stable substrate, clean water with adequate dissolved oxygen, and healthy fish populations for larval development (most mussel species have parasitic larvae that develop on fish gills). Sedimentation, water pollution, and dam construction are the primary threats to freshwater mussel populations in Texas.
Wildlife Management Plan Implications
Including Mexican fawnsfoot as a target species in your wildlife management plan demonstrates active management for a species of conservation concern in Texas. Your plan should document habitat conditions on your property, identify management practices that benefit this species, and establish monitoring protocols to track population trends over the 5-year plan period. Because this species carries conservation status, managing for it strengthens your plan and demonstrates the highest standard of land stewardship.

What does the conservation status of Mexican fawnsfoot mean for my property?
Mexican fawnsfoot is currently Federally proposed endangered and state threatened. This means the species receives legal protection and managing for it in your wildlife plan demonstrates compliance with conservation priorities. Active management for listed species can also open the door to conservation incentive programs.
How do I survey for Mexican fawnsfoot on my property?
Survey methods depend on the species and habitat type. For Mexican fawnsfoot, consult your ecoregion's TPWD wildlife biologist for recommended survey protocols. Document all observations with date, location, habitat description, and photographs when possible. Include survey results in your annual wildlife management plan activities log.
