**Both the Rock Pocketbook and the Texas Pigtoe were listed at the Federal and State level as “species of concern.” Texas Pigtoe is ranked as imperiled due to restricted range and scarce populations. LLELA has a nice-sized population near the confluence of the Elm Fork with the original river channel. Conservation status was based on the 2005 Texas Comprehensive Wildlife Conservation Strategy.
