Population Assessments and Propagation of Federally Listed Species to Address Recovery Criteria in the Powell River, Tennessee and Virginia.


April 2009 - May 2010


Objectives of this study are as follows: 1) search for new demes within under-sampled reaches of the river, 2) resurvey sites with endangered species (Wolcott and Neves 1994, Ahlstedt et al. 2005) to assess current status and recruitment, and 3) propagate juveniles from resident brood stock at new sites of occurrence to augment these demes. At least two Recovery Objectives (seek new populations, propagation) in recovery plans of the nine endangered species listed above will be addressed. In addition, new survey data on the three federal candidate species will determine their status in this river and provide an opportunity to initiate propagation to bolster those populations, to defer the necessity of federal listing.
