Análisis de cambios de coberturas en dos áreas de compensación forestal ubicadas en los municipios de la Cumbre y Dagua en el departamento del Valle del Cauca durante los años 2013, 2014 y 2020

Abstract

Coverage layers were generated on two lands in forest compensation called Villa María in the municipality of Dagua and also the Santa Fe estate in the municipality of La Cumbre, department of Valle del Cauca - Colombia. Coverages were generated for March 2020 (both properties), for December 2013 (Villa María) and August 2014 (Santa Fe) applying a supervised classification and implementing the Corine land cover classification legend adjusted for Colombia (CLC Colombia). In addition to updating coverage to 2020, a comparison was made with the periods 2013 and 2014, which were the initial years of the beginning of these compensations, and through this comparison the increase or decrease in coverage generated by the implementation of the compensation measure focused mainly on a forest restoration strategy. It could be determined that during the multitemporal analysis period (6-7 years) Increases in grassland coverings occurred mainly in exchange for a decrease in grassland-type coverings. However, there were increases in unwanted coverage in the processes of plant succession as the case of increased fern coverage, while for some sectors there was a decrease in tree cover. In this way, 50% of the areas developed positive changes that contribute positively to achieving more advanced successional states, but between 40% and 43% present a stagnation or deterioration in the desired process of plant succession, so it is recommended to implement measures to eradicate unwanted cover (mainly fern), planting of pioneer species and high-density afforestation in sectors with low changes in cover.
