In Mancilla Village, located in the municipality of Facatativá, economic activities related to agricultural production are driving changes in the landscape. These changes reduce native forest areas’ ecological conservation zones and decrease water resource flow. An urgent need for environmental restoration in the Mancilla micro-basin has been identified within this socioeconomic context. To address this, an ecological connectivity model was developed to identify new areas for environmental restoration. This model was based on a multitemporal analysis of land cover change for the years 1985, 2004, and 2016, the generation of a distribution model for the Margay (Leopardus tigrinus) species through MaxEnt, considering occurrence data for the species in Cundinamarca, including records within the Mancilla Village, and bioclimatic variables. A landscape fragmentation analysis was conducted based on land cover and the Patton Shape Index, identifying potential ecological corridors to implement in the most fragmented areas. Restoration zones were proposed based on land cover, drainage systems, and slopes. These proposed restoration zones have the potential to significantly improve the ecological connectivity and health of the Mancilla micro-basin. These analyses were performed using Geographic Information Systems (GIS). Notable results from the land cover change analysis revealed that artificial territories experienced the highest percentage change, increasing by approximately 0.54 ha due to population growth and the establishment of hydrocarbon industries. Dense shrubland decreased by approximately 30 ha due to deforestation caused by agricultural and livestock activities in the Mancilla Village. Regarding the analyzed fragmentation, the most affected area was riparian forest cover, primarily located near the Mancilla stream and its connecting drainage systems. Based on this process, 17 ecological corridors were proposed to enhance the spatial connectivity of riparian forests. Restoration efforts focused on protecting and conserving water resources through riparian forests. Importantly, these efforts were designed to involve and benefit the rural community of the micro-basin, highlighting the essential role of community involvement in the restoration process.

摘要

In Mancilla Village, located in the municipality of Facatativá, economic activities related to agricultural production are driving changes in the landscape. These changes reduce native forest areas’ ecological conservation zones and decrease water resource flow. An urgent need for environmental restoration in the Mancilla micro-basin has been identified within this socioeconomic context. To address this, an ecological connectivity model was developed to identify new areas for environmental restoration. This model was based on a multitemporal analysis of land cover change for the years 1985, 2004, and 2016, the generation of a distribution model for the Margay (Leopardus tigrinus) species through MaxEnt, considering occurrence data for the species in Cundinamarca, including records within the Mancilla Village, and bioclimatic variables. A landscape fragmentation analysis was conducted based on land cover and the Patton Shape Index, identifying potential ecological corridors to implement in the most fragmented areas. Restoration zones were proposed based on land cover, drainage systems, and slopes. These proposed restoration zones have the potential to significantly improve the ecological connectivity and health of the Mancilla micro-basin. These analyses were performed using Geographic Information Systems (GIS). Notable results from the land cover change analysis revealed that artificial territories experienced the highest percentage change, increasing by approximately 0.54 ha due to population growth and the establishment of hydrocarbon industries.
