Lynx, grizzly bear and salmon could be the winners in a new plan to link the current patchwork of parks, national forests and recreation areas in Washington's North Cascades. Along with the National Park Service, groups like The Wilderness Society, the National Parks and Conservation Association and the Canadian Earthcare Society will host a three-day conference, Nature Has No Borders, to push the plan closer to reality. Biologists and conservationists will meet with officials such as John Reynolds, deputy director of the Park Service, Rep. Bruce Vento, D-Minn., Canadian park managers, and the chief of the Cascades N'Laka Pamux Nation. They hope to design a proposal that could end agency and international divisions within the North Cascades. The conference costs $175 per person and takes place March 25-27 at the University of Washington's Architecture Hall in Seattle.
