Project: Development and conservation in the upper part of the Cahabon river watershed. Photo documentation: Orchard Management This orchard is an example of planting fruit trees as a buffer between the milpa (corn field) and the cloud forest, as a dis-incentive to agricultural burning. Orchard buffers prevent the escape of fires into the forest. Sept. 2008. Each large pear weighs a pound. In one season they harvest 400-500 pounds per tree. At Q1 per pound = Q 400-Q500, or $50-$65 per tree per year. A family may have 5-8 pear trees. Sept. 2008.
