Monster Seminar JAM - Dammed Fish: Science for Recovery Planning in the Interior Columbia Basin

Presenter: Dr. Michelle McClure, Conservation Biol Division, Northwest Fisheries Science Center

Long Description:
More Information:
Technical Recovery Teams for anadromous salmonids were formed to provide scientific and technical input into the recovery planning process. Their tasks include defining population structure for listed ESUs, devising biological viability criteria for those ESUs, and evaluating proposed recovery strategies. In this talk, I present the Interior Columbia Technical Recovery Teams work to date in these areas. We defined population structure, in both currently accessible and historically accessible areas using genetic, geographic, ecological and demographic information. We then developed quantitative abundance and productivity criteria for populations, as well as more qualitative criteria for spatial structure and diversity. These viability criteria have allowed us to develop several potential scenarios for ESU-level viability and to assess the relative change in ESU-level risk that re-introduction efforts might provide. In order to evaluate the efficacy of proposed recovery strategies, we have, in collaboration with Rich Zabel, developed a stochastic life-cycle model to evaluate potential viability of populations under alternative future hydropower and climatic scenarios. This work, coupled with additional work evaluating likely impairments to habitat status throughout the Columbia Basin indicates that the potential for recovery, and needed improvements to achieve that status vary widely across populations.
