Evaluation of Loblolly Pine Management Regimes in Mississippi for Biomass Supplies: A Simulation Approach

摘要: Alternative management regimes of loblolly pine (Pinus taeda) plantations were evaluated and compared for joint production timber biomass exclusively in Mississippi. The PTAEDA3.1 computerized yield simulator was used to predict growth effects various site preparation techniques, initial planting densities, thinning activities. Evaluation criteria included land expectation values (LEVs) mean annual increment. Results indicated that sites with a index 50 –70 (base age 25) yielded average stem residues 0.86 –1.20 tons/ac, from which 39.8 – 47.4 gallons ethanol could be produced. Inclusion pulpwood as feedstock would approximately double biofuel production. Culminating sustainable outputs total using intensive unprofitable on all because high costs low prices. Sensitivity analyses LEVs optimal strategies sensitive changes price relative sawtimber. rise the increase woody availability biofuels. It also boost practices, such preparation, closer tree spacings, earlier thinnings, shorter rotation ages.
