BLM New Mexico John D. Dingell, Jr. Act Designations


On March 12, 2019, President Trump signed Senate Bill 47 into law as Public Law 116-9, the John D. Dingell, Jr. Conservation, Management, and Recreation Act.  This act will have an impact on public lands across the State of New Mexico. BLM New Mexico has been actively involved in the implementation of the law, and looks forward to working with local communities, counties and the State to implement the new land designations.  The Act will help protect recreation opportunities and provide access to public lands by consolidating Federal and State lands. We invite you to explore the new recreation and national conservation lands designations.
