Research overview: corridor prioritization and stepping stones

With limited resources, conservationists must decide which corridors to protect first, and whether continuous corridors or chains of habitat stepping stones best serve wide-ranging cats. This overview surveys research on prioritizing connectivity investments, ranking corridors by their importance to gene flow, the threats they face, and the feasibility of securing them. Studies model how networks of small habitat patches can facilitate dispersal across otherwise inhospitable landscapes, and how the loss of a single key linkage can disproportionately fragment a network. Researchers integrate ecological value with cost and threat to guide spatial planning. The overview frames corridor prioritization as a practical extension of connectivity science, acknowledging that not all linkages can be saved and that strategic choices must be made. It matters because targeting the most critical and most threatened corridors maximizes the conservation return from scarce funding for maintaining connectivity across big cat landscapes.
