Resource Management Boards


Through the respective adverse affects settlement agreements (ex: Northern Flood Agreement, Grand Rapids Forebay and others), Resource Management Boards (RMBs) were established to co-manage the natural resources in defined areas (Resource Management Areas). Manitoba Indigenous Relations serves as the provincial lead in the management and implementation of the RMBs established under these agreements.  Each of the ten existing RMBs are mandated to develop and implement land use plans and resource management plans.

The boards are responsible for approximately 35 million acres or 22 per cent of Manitoba’s Crown land base.
