This map depicts the density of "More Resilient" cells (defined as the top two quintiles from the stratified resilience dataset) within a 3-km radius of every cell. This provides important additional context when making land protection or restoration decisions. Cells with higher density values are embedded in a larger resilient landscape. These areas are more likely to support biodiversity and ecological function over time in a changing climate. To quantify resilience at the landscape scale, we used a density function, where all cells classified in the final top two resilience quintiles were included in the density calculations, regardless of their underlying Ecofacet, and all other cells were ignored.

This project will provide a comprehensive synthesis of beaver recolonization science and techniques for successful reintroduction or population expansion through a thorough, in-depth, coordinated review of all North American beaver-related information, including identification of research gaps and data needs, and recommendations for project implementation. This information will be disseminated through a series of one-day workshops.
