At WCS, saving a species does not simply mean not allowing them to go extinct. Rather, saving a species means ensuring that they continue to perform their ecological roles across their present and, if possible, historical range. To set priorities for saving a species we have developed a process called “range-wide priority setting”. RWPS is based on the premise that saving a species requires: consideration of the species across its historical range; recognizing that populations exist in ecological settings that differ not only in terms of genetics, but also ecology and behavior; and identifying those populations and/or opportunities for restoration where the potential for long-term conservation is greatest. The process consists of two steps: 1) a geographically-based, systematic evaluation of the status and distribution of the species across its historical range; and 2) a prioritization of conservation investment in identified population strongholds and/or restoration opportunities. To date, RWPS exercises have been run for many species, including jaguars, Asian elephants, Eastern chimpanzees, American bison, and Mongolian gazelle. Future RWPS activities will include climate change forecasts, predicted habitat changes and other components in the prioritization of future conservation activities. Conservation Support provides technical assistance to WCS field programs to undertake RWPS exercises and to publish and disseminate the results.
