This spring, the New Mexico legislature passed Senate Bill 228, the Wildlife Corridors Act, becoming the first state to enact legislation of its kind. Per the bill, New Mexico's Department of Transportation and Game and Fish will work together to compile a statewide Wildlife Corridors Action Plan that will identify existing migration routes and places where New Mexico highways or other developments have impeded wildlife movement along with projections of how drought and other effects of climate change may impact the daily and seasonal movement of wildlife. Additionally, the plan will include a list of priority roadway infrastructure projects such as fencing, underpasses and overpasses that will help protect both wildlife and the traveling public. Although an initial plan will be due after a year, the Action Plan will be a living document that will be updated as new research and data become available and how wildlife are using the landscape across the state. The effort to pass the bill brought together the Departments of Transportation and Game and Fish along with environmental and sportsmen organizations, private landowner groups and tribes. Throughout the process, there were a number of in-depth conversations about how to shape this process while balancing the safety of the traveling public versus the broader landscape, species of concern versus large mammals like elk, deer and pronghorn, as well as ensuring involvement by tribes and private landowners. This panel will feature the bill's sponsor, Senator Mimi Stewart, along with representatives from New Mexico Game and Fish, the Department of Transportation, Defenders of Wildlife and Wildlands Network.
