The objective of this study was to characterize the woody perennial vegetation of a pasture from Tolima´s Magdalena valley in Colombia. The forest inventory was carried out by establishing temporary sampling plots. The estimation of canopy occlusion was obtained through digital photographs of tree crowns taken near sunset and were analyzed with Gap Light Analyzer software. Transmitted Photosynthetic Active Radiation (PAR) was estimated with an Accupar ceptometer LP-80. A total of 21 woody perennial species was found in a sampling area of 54 ha. Pseudosamanea guachapele (64%) and Prosopis juliflora (63%) were the tree species with the lowest occlusion, suggesting its potential use in silvopastoral systems; some timber species have potential as additional income to the farmer: A significant diversity of woody perennial species with potential to be introduced into pastures, without affecting the production of edible dry matter for livestock were found.Downloads
