Editors' Summary: Public lands interest groups expect widespread litigation in the late 1980s over the 125 national forest land and resources management plans due under the National Forest Management Act (NFMA). This Comment speculates on the issues that will surface in the coming litigation, focusing on three controversial parts of the NFMA: §6(k), dealing with designation of lands unsuitable for timber management; §13, dealing with departures from sustained-yield management for timber; and §6(g)(3)(B), dealing with preservation of forest diversity.
