Getting back to nature is not cheap, at least not when it comes to restoring the natural grandeur of California's Yosemite National Park. That is why the Yosemite Conservancy is giving one of its biggest yearly grants to the park.

Conservancy VP Jerry Edelbrock says the group's $15 million gift will go toward rebuilding hiking trails, protecting the Great Gray Owl and restoration of the Mariposa Grove of giant sequoias, all of which would be beyond the park's own budget.

The Park Service closed Mariposa Grove to the public last year so it could remove a parking lot that had been constructed on the roots of the trees themselves. They also had to take out filler that had been put in natural water courses. Now, work has to be done to put back what nature intended to be there.

The actual labor will come from the California Conservation Corps, a group of young men and women ages 18 to 25 who serve their state by working to protect and restore our natural resources.  The money comes from donations to the Yosemite Conservancy, which has been helping to preserve and protect Yosemite National Park for more than 90 years.
