Minimum Requirements Analysis
A minimum requirements analysis (MRA) is required by law whenever land managers are considering a use prohibited by Section 4(c) of the Wilderness Act of 1964. Some agency policies may also require an MRA for other uses or activities in wilderness. Although there are other ways to complete an MRA, the Minimum Requirements Decision Guide (MRDG) is a process that was developed by the Arthur Carhart National Wilderness Training Center to help land managers make informed, defensible decisions that comply with the Wilderness Act. The MRDG has been widely adopted and is required by some agencies.
