Apoyo en el montaje, seguimiento, análisis del estado y dinámica del bosque de parcelas permanentes en el municipio de Vigía del Fuerte, Antioquia

Abstract

In the municipality of Vigía del Fuerte, department of Antioquia, an ecoregion of the Chocó biogeográfico, the monitoring of a total of 60 permanent plots established under the cluster methodology of the National Forest Inventory (IFN) was continued, based on the follow-up of 45 initial plots and the installation of 15 additional ones. Four forest management scenarios were studied: sustainable forest management, traditional/conventional, without any type of intervention, and post-sustainable forest management. The results revealed a high diversity of species, with a great presence of rare species and the hyperdominance of families such as Fabaceae, Moraceae, and Arecaceae. The structural analysis highlighted the sustainable forest management scenario, which, due to its selective management, maintained equity and diversity by leaving remnants, highlighting the dominance of the species Pentaclethra macroloba (Capitancillo), and showed the diametric distribution with the highest regeneration potential, a large number of young individuals, and the highest percentage of basal area. In contrast, traditional management showed structural deterioration and a displacement of canopy species by pioneer species due to unplanned resource use, while the scenario without any type of intervention favored the dominance of Euterpe oleracea (Murrapo/naidí), restricting other species, which generated patches of specialists and low regeneration. The analysis of richness and diversity confirmed that the sustainable forest management and post-sustainable forest management scenarios had a very similar behavior, which supports the effectiveness of silvicultural management to conserve ecological structure and diversity, achieving a balance between preservation and the provision of ecosystem services.
