Cost Effective Mitigation Strategy for State Listed Freshwater Mussels

Transportation agencies continue to promote economic growth through infrastructure development; however, with this comes the responsibility of preserving important natural resources. When road and bridge construction is proposed, an environmental impact assessment is conducted to determine the potential threat that a given project has on sensitive species or ecological areas. For freshwater mussels, surveys are often performed to determine whether mussels are present and their distribution within the project area. If mussels of concern are found, a relocation plan is often implemented wherein mussels are moved to minimize impacts from construction activities. In Texas, there are no current standard protocols for establishing presence or absence of state-threatened, federally-listed or candidate species within a bridge construction project area or guidelines for when and how to conduct mussel relocations. The overall goal of this project is to provide Texas Department of Transportation (TxDOT) with guidelines for conducting freshwater mussel surveys and relocations.
