Book excerpt: "Urban Wilderness provides an inspiring and clear-sighted commentary on the conditions and potentials of nature in urban America. We are encouraged when we read about the remarkable citizen-led effort in Milwaukee to restore the natural corridors of its major metropolitan watershed for wildlife and to protect the scenic heritage that had largely been ignored until recently. Daniel opens a door to understanding how regional and global forces shape a shared urban landscape and how the "greening" of Milwaukee's industrial river benefits wildlife and nature, thus enhancing urban living. He leads us on a voyage of discovery - not of faraway lands, but of his own backyard - and shows us that it is just as important to discover and protect the familiar as it is to seek out new and unfamiliar places."--BOOK JACKET.
