Evaluating the Efficacy of Mussel Relocation in Texas with In-Situ Field Studies and the Development of a Texas Mussel Database
| 项目名称： | Evaluating the Efficacy of Mussel Relocation in Texas with In-Situ Field Studies and the Development of a Texas Mussel Database |
| 摘要： | The Texas Department of Transportation (TxDOT) is responsible for mitigating impacts to natural resources at road and bridge construction sites. For freshwater mussels, environmental assessments to ensure compliance with state (Texas Parks and Wildlife Code Title 5, Subtitle B, Chatpter 68) and federal (16 U.S. Code Chapter 35) endangered species laws are conducted to determine whether sensitive species occur within the project area. If mussels are found, they are translocated to in-stream refugia to prevent or minimize impacts resulting from construction activities. However, it remains unknown whether translocation is an effective conservation tool. Another issue facing TxDOT is how to best prioritize or identify projects that require mussel surveys or relocations. Currently, information from the TPWD Texas Natural Diversity Database is used to determine whether an in-stream survey is warranted, but this database is not kept up-to-date and the information provided is often too coarse for determining whether threatened species actually occur near a proposed bridge project. As a result, TxDOT continues to expend valuable resources for surveys where state-listed mussels are not present. The Performing Agency shall conduct several experimental mussel relocations to evaluate lethal and sub-lethal impacts to translocated mussels and to provide TxDOT with an online mussel database to be used for planning mussel surveys and trans-locations. |
