The Nature Conservancy is responsible for preserving over two million acres of land, as well as innumerable rare and endangered plants and animals. For my money, they manage their purchases with the best network of volunteer and professional land stewards. Recently, The Nature Conservancy has gone international because many of the birds we protect here winter south of the border. “To save them here, they must be saved there as well.” A fringe benefit of joining is a 4-color, top-notch quarterly.
