Lake Tahoe Basin researchers will discuss water clarity, gasoline emissions, air quality, forest health and federal involvement in research, among other topics, at an annual research symposium Tuesday, Oct. 20. To be held at the North Lake Tahoe Conference Center in Kings Beach, Calif., the symposium will draw together scientists from the University of California, Davis; University of Nevada, Reno; the U.S. Geological Survey; U.S. Forest Service; and the Tahoe Regional Planning Agency. The meeting's purpose is for Tahoe Basin researchers to share research progress, identify areas of common interest to further integrate research activities, collaboration and the transfer of scientific information for use in land-management decision making. Nevada Sen. Harry Reid has been invited to open the program at 8 a.m. Among those scientists from UC Davis who will make presentations are Charles Goldman, veteran Tahoe researcher and professor of limnology, who will discuss the state of the science from a historical perspective; Tom Cahill, professor emeritus, who will discuss air quality in the Tahoe basin; Michael Barbour, environmental horticulture professor, who will discuss forest health and structure; and John Reuter, researcher with the UC Davis Tahoe Research Group, who will discuss the role of research and monitoring with regard to the basin's restoration needs. Other topics to be discussed during the day-long meeting include water quality and watershed processes, interdisciplinary approaches to solving Lake Tahoe environmental problems and socio-economic factors. The meeting will continue on Oct. 21, when resource agencies and public groups will lead discussions on research needs and policy.
