摘要:A multitemporal analysis of the landscape of the municipality of Puerto Berrío (Antioquia), during the years 1985, 2001, and 2011 was carried out using remote sensors throughout an area of 15.000 ha. In 2001, it was possible to observe significant dynamics in the structure and composition of the landscape, as well as substantial heterogeneity, which tended to homogenize in 2011. “Positive” changes from grass to stubble and forests were identified between 1985 and 2001, while the period between 2001 and 2011 showed loss and fragmentation of forests. This transformation is related to the abandonment of lands and displacement that took place during the 1980s and 1990s, as well as to the subsequent return of the population and reactivation of economic activities during the first decade of the 21st century. It was also possible to estimate some potential north-south connectivity routes between the forests under study, thus showing a high degree of crossfragmentation of the landscape.
