National Forest Management Act

National Forest Management Act - Amends the Forest and Rangeland Renewable Resources Planning Act to direct the Secretary of Agriculture to identify and report to Congress annually all lands in the National Forest System which either need to be reforested or are not growing at their best potential rate.

Requires the Secretary to annually transmit to Congress an estimate of the sums necessary to replant and otherwise treat an amount of land equal to the acreage to be cut over that year plus a sufficient portion of those lands currently in need of replanting or treatment so as to eliminate the backlog of lands in need of reforestation within eight years of the enactment of this Act. Requires the Secretary, subsequent to such eight-year period, to annually transmit to Congress an estimate of the sums necessary to replant and treat lands being cut over and to maintain planned timber production on other lands within the National Forest System in order to prevent the development of a backlog larger than the needed work at the beginning of the fiscal year.
