Douglas Tallamy’s first book, “Bringing Nature Home,” awakened thousands of readers to an urgent situation: wildlife populations are in decline because the native plants they depend on are fast disappearing. His solution? Plant more natives. In this new book, Tallamy takes the next step and outlines his vision for a grassroots approach to conservation. “Nature’s Best Hope” shows how homeowners everywhere can turn their yards into conservation corridors that provide wildlife habitats.
