"The partnership with Weyerhaeuser will help facilitate the development of a watershed-based conservation plan that will protect key wetlands, help maintain watershed health, enhance best management practices which will further advance sustainable development, and provide better information to protect key nesting and stopover areas for a multitude of North America's migratory water-birds," said Garry Stewart, DUC's manager of conservation programs for the western boreal. "These watersheds of the western boreal forest are vital to northern communities and provide unparalleled economic, environmental and social benefits to all Canadians."

The project will begin in July 2006 and include collaborative research and monitoring initiatives that protect the integrity of watersheds, riparian habitats, water and wetlands.

"Weyerhaeuser is pleased about developing another partnership with an environmental organization as progressive and successful as Ducks Unlimited Canada. Projects such as this are invaluable in providing necessary scientific data for our foresters to use in enhancing our sustainable forest management practices," said Tom Holmes, Vice-President, Forestlands, Weyerhaeuser Company Limited.
