Migrating wildlife species across the globe face a dire predicament as their traditional migratory routes are cut off by human encroachment. Forced into smaller and smaller patches of habitat, they must compete more aggressively for dwindling food resources and territory. This is more than just an unfortunate side effect of human progress. As key species populations dwindle, ecosystems are losing resilience and face collapse, and along with them, the ecosystem services we depend on. Healthy ecosystems need healthy wildlife populations. One possible answer? Wildlife corridors that connect fragmented landscapes.

This new and expanded second edition of Corridor Ecology: Linking Landscapes for Biodiversity Conservation and Climate Adaptation captures the many advances in the field over the past ten years. It builds on concepts presented in the first edition on the importance and practical details of maintaining and restoring land connectivity. New to this edition is a guest-edited chapter on ecological connectivity in oceans, including a detailed discussion on pelagic marine corridors and how coastal corridors can provide critical connectivity between marine protected areas. Another new chapter considers the effects of climate change on habitat and offers recommendations on designing effective corridors as landscapes change with shifting climate conditions. The book also includes a discussion of corridors in the air for migrating flying species, from birds to bats, butterflies, and even plant propagules—a concept so new that a term to describe it has yet to be coined. All chapters are thoroughly revised and updated.

Practitioners as well as serious scholars of landscape ecology and the science of protecting biodiversity will find this new edition of corridor ecology science an indispensable resource.
