Anthropic impacts on forest cover in the Iracá river basin, Colombian plains piedmont
Between August 2023 and September 2024, a study was conducted in the Iracá river basin in the Colombian plains foothills to evaluate the current state of the forests as a function of the land use regime. During this period, two critical variables of anthropogenic impact were measured: fragmentation...

During this period, two critical variables of anthropogenic impact were measured: fragmentation and loss of connectivity of forest corridors. The study was based on photographic records and field walks and subsequent geospatial analysis with LANDSAT images to establish the degrees of fragmentation of the native forest. It was found that the forest corridors have suffered some degree of structural fragmentation leaving relicts that show an insular spatial arrangement. Gaps were identified, in some cases greater than 1 kilometer, that cut the continuity of the forest corridors, affecting the biotic flow of fauna and impacting the network of small tributaries, compromising ecosystem functionality. Entre agosto de 2023 y septiembre de 2024, se realizó un estudio en la cuenca del caño Iracá en el piedemonte llanero colombiano, para evaluar el estado actual de los bosques en función del régimen del uso del suelo. Durante este periodo se midieron dos variables críticas de impacto antrópico: la fragmentación y las pérdidas de conectividad de los corredores boscosos. El estudio se basó en registros fotográficos y recorridos en el terreno y en el posterior análisis geoespacial con imágenes LANDSAT para establecer los grados de fragmentación del bosque nativo. Se encontró que los corredores boscosos han sufrido algún grado de fragmentación estructural dejando relictos que muestran una ordenación espacial insular. Se identificaron brechas, en algunos casos superiores a 1 kilómetro, que cortan la continuidad de los corredores boscosos, lo que afecta el flujo biótico de la fauna e impacta la red de pequeños tributarios comprometiendo la funcionalidad ecosistémica.
