More than 30 presentations related to ecological changes in the region highlight the third Conference on Klamath-Siskiyou Ecology, which begins today in Selma.

The three-day event brings together scientists, resource managers and others to discuss the scope and consequences of environmental change in the ecologically diverse Klamath-Siskiyou bioregion.

There will be addresses by leading scientists, a symposium and panel discussion on climate change, workshops and field trips.

The conference will be held at the Selma Community Center, 18255 Redwood Highway, Selma.

The keynote address begins at 1:10 p.m. and features Susan Harrison of the Department of Environmental Science and Policy at the University of California Davis. She will focus on the influence of climate change on biodiversity in the Siskiyou Mountains based on resampling of vegetation transects that Robert Whittaker studied from 1949 to 1951.

Other presenters include Frank Lang, emeritus professor of biology, Southern Oregon University, and forest ecologist Dominick DellaSala, executive director of programs for the National Center for Conservation in Ashland.

Speakers throughout the conference will address vegetation regeneration, climate conservation planning, climate stream flow changes and the aftermath of high intensity fire. Field trips will include tours to the 2002 Biscuit fire, Darlingtonia fens and other areas.

The conference, whose theme is "Sustaining Biodiversity in a Changing Environment," will cover a broad spectrum, including forest ecology and management, watersheds and fish, wildlife ecology, endemic and sensitive species, forest pathogens and invasive species, and hidden diversity.

The goals of the conference is to provide a forum to share the latest research about environmental change.

The conference is hosted by Deer Creek Center for Field Research and Education. Cosponsors include the Siskiyou Field Institute, Southern Oregon University Biology Department, National Park Service Klamath Network, National Center for Conservation Science and Policy, Klamath Bird Observatory, Siskiyou Chapter Native Plant Society of Oregon, The Nature Conservancy, Jefferson Fish Society and Siskiyou Project.
