The overall goal of this project is to provide guidance on genetic considerations that should be addressed prior to implementing controlled propagation through development of a conceptual framework and case study. The completion of these tasks will provide information that can be used to inform species-specific genetic management plans and help operationalize controlled propagation, if needed. The specific objectives of this study are: (1) Outline specific steps that managers should ask in making determinations regarding whether or not to initiate captive propagation; (2) Conduct a range-wide survey of genetic variation in Lampsilis bracteata, that will allow identification of distinct populations and identification of past events that have affected the genetic diversity of this species. This information will be used to develop future documents (SSA, Recovery Plan, Genetic Management Plan); (3) Develop a species specific genetic management plan for L. bracteata (assuming one is warranted) to guide propagation activities so as to minimize loss of genetic diversity and artificial selection. Summarized below and arespecific details of each task, which are to be carried out in phases over a period of 3-4 years.
