MEDFORD (AP) - Conservationists are proposing a third national monument in southwestern Oregon to protect rare native plants and wildlife corridors.

The proposed Siskiyou Crest National Monument would be made up of 600,000 acres of federal land straddling the Oregon-California border, and serve as a habitat link between the Oregon Caves and Cascade-Siskiyou national monuments.

"With climate change, places like this that act as unbroken corridors will become hugely valuable for survival of species as they move around the landscape," said Laurel Sutherlin, a naturalist with the Klamath-Siskiyou Wildlands Center in Ashland.

Center director Joseph Vaile said hundreds of jobs could be created to restore forests, streams and roads after decades of logging in the area filled with rare plants and important wildlife corridors.

"We're still in a real preliminary stage," Vaile said. "We've been talking to scientists and other folks who have been working on this area for a long time to figure out the boundaries."

The monument would span about 80 miles and include the Red Buttes and Siskiyou wilderness areas on the Rogue River-Siskiyou and Klamath national forests. The area would be roughly bounded by Ashland, Ruch and Takilma in Oregon and Klamath River and Happy Camp in California.

Dave Schott of the Southern Oregon Timber Industries Association argued that shutting out logging in the area would make it harder to thin crowded forests to reduce fuel buildups that contribute to wildfires.

"We have nothing against saving good-sized timber," said Schott. "That's commendable. But if you are doing that to the inclusion of all timber harvests, you are creating a timber hazard."

The U.S. Forest Service and timber industry have cited a build-up of fuels in forests from a century of putting out fires as a prime reason for the growing number and intensity of wildfires.

Scientific research is increasingly pointing to changes in climate, such as drought and longer hotter summers.
