Who is the Natural Resources Trustee?

State Natural Resource Trustees are appointed by the governor of each state. In addition to state trustees, the President of the United States and Native American tribes appoint federal and tribal trustees. New Mexico frequently shares trust responsibilities for natural resources with other Trustees.
