Published by the Center for Large Landscape Conservation, this report is a primer for practitioners working to advance wildlife corridor and ecological connectivity conservation. This report is intended to provide a high-level summary of the fundamentals of wildlife corridors and ecological connectivity to people engaged in management and conservation actions. We clarify the terms used to describe connectivity and provide tangible examples of different kinds of corridors and linkages and how they work. We describe the many different ways to identify places on the landscape for connectivity and wildlife corridors, including a wide range of methods, tools, and models. Finally, because policy is critical to support conservation efforts and ensure their longevity, we provide examples of existing policies that support wildlife corridors and connectivity and how they can be replicated or expanded to other jurisdictions.
