The Maryland Reforestation Law protects Maryland's forests from removal without adequate replacement. This law requires an acre-for-acre replacement of forest removed during road construction. The law also specifies the minimum required plantings and planting locations.

The Maryland Department of Natural Resources (DNR) Forest Service administers this law. See the text of the law on the DNR website here and below.
