Abstract

The ﬂoristic composition, structure and dynamism were determined after 57 years of enrichment strips, located in a University Forest EL Caimital, municipio Obispo, Barinas - Venezuela. Two areas were selected: one formed by the primary forest (witness) and another one formed by Fajas de Enriquecimiento in a secondary forest. In the forest were evaluated 3 plots of 1,3 ha (enrichment strips) and 3 plots of 1 ha random selected in the primary forest (witness). Were evaluated individuals with diameters bigger than 10 cm, in each one of that plots, three sub-plots of 20 m2 were measured, to study all the species in the understory. The forest is in the Banco´s fisiography. In the primary forest, 49 tree species grouped in 24 families were found and 45 species grouped in 23 families in the secondary forest. The most representative families were Arecaceae, Leguminosae, Moracea, Malvaceae and Euphorbiaceae to both forests. In the Importance Value Index (IVI) and Expanded Importance Index (IIA) the most representative species were Trophis racemosa, Attalea butyraceae y Lonchocarpus pictus (primary forest) and Attalea butyracea, Hura crepitans y Lonchocarpus pictus in (secondary forest). The Margalef’s index were > 5.
