a. Assessment and Prediction of Effects of Selenium Exposure to Larval Razorback Sucker - Dan Beyers reminded the Committee that he is now doing additional work with higher selenium concentrations. They didn't see the amount of bioaccumulation in the food chain that they expected, so that may be why they didn't detect adverse effects. Tom Nesler expressed concern that we seem to be continuing additional selenium studies without eventually seeing some kind of an effect. Tom also noted that it would have been helpful to explain how the bioacccumulation problem is being remedied in the subsequent studies; Dan will add a paragraph to address that. Art Roybal will submit written comments. The Committee approved the report as final with the foregoing changes.



5. Land acquisition criteria/BC involvement - Pat Nelson provided a handout and gave an overview of land acquisition criteria. Tom Pitts asked >Dave Soker to periodically provide a table identifying land acquired and acquisitions in process. The Committee felt the criteria were generally appropriate, although they did raise some questions about prioritizing the addition of new habitat versus protecting existing habitat. Ed Wick suggested that if the Program is stocking many adult razorbacks, then we also need to provide them habitat. Pat replied that larval habitat is good for both juveniles and adults, whereas adult habitat is not useful to larvae.
