The 1995 Resource Management Plans (RMPs) for the 6 western Oregon BLM Districts were based on the Land Use Allocations and Management Direction from the Northwest Forest Plan (NWFP). The RMPs initially declared an Allowable Sale Quantity (ASQ) of 211 million board feet (MMBF) on a sustainable basis and made no estimation of the short-term volume potential from the reserves.
The declared ASQ was based on a 608,000 acre harvest land base, 27 percent of the BLM forest, being fully available for sustained yield management. The declared ASQ was based upon the assumption that 85 percent of the volume would come from regeneration harvest in mature forest generally over age 80. The remaining 15 percent was assumed to come from intermediate thinning of younger forest.
In 1999 the RMPs were formally evaluated and the ASQ was reduced to 203 MMBF due to updated information on the harvest land base in the Eugene and Coos Bay Districts. Implementation during the first three years of the plan reflected a ramp up period and was below the declared ASQ. The mix of regeneration harvest and thinning was generally consistent with the RMP assumptions for the ASQ. The RMPs were formally evaluated again in 2004 and 2011. Both evaluations found that:
