Description : Since 1980, one of the country's most acclaimed rock/blues pianists has developed into one of our most respected conservationists and tree farmers. Over the last two decades, Chuck Leavell and his wife Rose Lane have transformed Charlane Plantation in middle Georgia into a textbook tree-farming enterprise--and in the process Leavell has become a nationally recognized spokesman on behalf of America's forests. In "Forever Green, Leavell steers a well-reasoned course for the future of America's forests. He points out that wood is one of our most critical resources, one that must be wisely used and conscientiously renewed. Leavell's message is frank but encouraging. Thanks to pressure applied by environmental and conservation groups, to responsible government policy, and to an ever-rising social consciousness concerning all our natural resources, we are making progress in forest management. And with the leadership of Leavell and others like him, the American forest does have hope.
