摘要: Silvopasture is reemerging as a land use in the southern US. Alternate treatments based on field trials for timber and pasture beef cattle production were financially evaluated. Multiple-use management aspects of these systems further illustrated by addition fee hunting. Land Expectation Values (LEVs) lower when silvopasture compared to steer grazing only. However, favorably some treatments. LEVs higher commercial forest plantation applications similar sites. promote multiple-use under an environmentally friendly cropping system whereby certain types wildlife can thrive. This particularly relevant light recent increases hunting South. reduced $289, $200, $151 ha−1 at discount rates 5%, 7%, 9% respectively, was excluded recommended treatment. The monetary value component this be interpreted expected gained per hectare rotation perpetuity part plan. On average, it represented 8.6% gain Results from study support potential South private landowners. Cattle improved forage commercially productive loblolly pine (Pinus taeda) stands relieve annual cash flow problems inherent tree production.
