Análisis multitemporal y de fragmentación de los parques nacionales naturales Yaigojé Apaporis, río Puré, Cahuinarí y Amacayacu entre 2007 - 2018

Abstract

Los cambios naturales o antrópicos pueden propiciar procesos de fragmentación, lo cual tiene innumerables efectos sobre los bosques amazónicos. Este fenómeno es dinámico y por tanto mediante un análisis multitemporal y de fragmentación en los parques nacionales naturales Yaigojé Apaporis, Río Puré, Cahuinarí y Amacayacu. Para efectuar dicho análisis se emplearon como insumo la cartografía generada por parques nacionales naturales de Colombia, específicamente para las áreas pertenecientes a Yaigojé Apaporis, Río Puré, Cahuinarí y Amacayacu años 2007,2012,2014,2016 y 2018, adicionalmente los indicadores de fragmentación se obtuvieron mediante la aplicación V-LATE (vector-based landscape analysis tools extension). Se encontró para el parque Yaigojé Apaporis una pérdida de 4319.01 ha de Bosque denso alto de tierra firme, a pesar de ello esta cobertura muestra un índice CAI más elevado del parque Yaigojé Apaporis con 94.08%. El parque Río Puré mostro un total de 12 coberturas de las cuales 11 pertenecen a bosques y áreas seminaturales, encontrando que el bosque denso alto de tierra firme es la cobertura con mayor disminución de área con 854.54 ha siendo esta misma cobertura la que presento mayor índice CAI con 97.55% representados en 81 áreas núcleo. Los parques Cahuinarí y Amacayacu muestran un comportamiento similar, disminuyendo la perdida de coberturas naturales en los años más recientes. Se observa para los 4 parques naturales objeto de estudio una mayor pérdida de coberturas naturales entre los años 2007-2012, dicha disminución se va atenuando al avanzar los años hasta el 2018, en donde las métricas de fragmentación indican un alto de grado de conservación de las coberturas, no obstante replicar este análisis a una escala más detallada ayudara a tener una perspectiva clara y cercana sobre donde focalizar el manejo de estos parque nacionales naturales.

Natural or anthropic changes can promote fragmentation processes, which have innumerable effects on Amazonian forests. This phenomenon is dynamic and therefore through a multi-temporal and fragmentation analysis in Yaigojé Apaporis, Río Puré, Cahuinarí and Amacayacu Natural Parks. To carry out this analysis, the cartography generated by natural national parks of Colombia was used as input, specifically for the areas belonging to Yaigojé Apaporis, Río Puré, Cahuinarí and Amacayacu years 2007, 2012, 2014, 2016 and 2018, additionally the fragmentation indicators are obtained using V-LATE application (vector-based landscape analysis tools extension). A loss of 4319.01 ha of dense highland forest was found for the Yaigojé Apaporis park, despite this coverage shows a higher CAI index than the Yaigojé Apaporis park with 94.08%. The Río Puré park showed a total of 12 covers, of which 11 belong to forests and semi-natural areas, finding that the dense highland forest is the coverage with the greatest decrease in area with 854.54 ha, this same coverage being the one that presented the highest index CAI with 97.55% represented in 81 core areas. The Cahuinarí and Amacayacu parks showed a similar behavior, reducing the loss of natural cover in the most recent years. For the 4 natural parks under study, a greater loss of natural covers is observed between the years 2007-2012, this decrease is attenuated as the years advance to 2018, where the fragmentation metrics indicate a high degree of conservation of coverage, however replicating this analysis at a more detailed scale will help to have a clear and close perspective on where to focus the management of these natural national parks.
