The Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974, as amended by the National Forest Management Act of 1976 (NFMA), was passed to make natural resource planning more rational and accountable. The RPA value is defined in terms...

Several fire retardants in current use were dropped from the Canadair CL-215 to determine drop height effects and for evaluation of the tank and gating system. Mathematical models for each retardant and load size were developed for predicting the...

Experimental evidence from 250 test fires confirms the general formulation of Rothermel's 1972 mathematical model for predicting fire spread in wildland fuels. Numerical coefficients are reevaluated for the empirical relations governed by fuel bed...

This paper develops regional recreation supply and demand projections by combining coefficients from the national 1989 RPA Assessment models with regional regressor values. Regional recreation opportunity estimates also are developed, based on...
Estimates of percent canopy cover generated by the Forest Vegetation Simulator (FVS) are corrected for crown overlap using an equation presented in this paper. A comparison of the new cover estimate to some others is provided. The cover estimate is...
