North American protected area connectivity

These data represent the least-human modified corridors that link select protected areas across the North American protected area network using least-cost and circuit theory approaches. We represented movement cost by creating a resistance surface using data on human modification (Theobald et al. 2020). Priority corridors modeled using least-cost or circuit theory methods are those in which cost-weighted distances between protected areas are minimized or current flow is maximized, respectively.
