Cambios en la avifauna de un relicto de bosque en la franja periurbana de Bogotá a lo largo de catorce años

Abstract

A lo largo de varios siglos, la vegetación nativa de la parte plana de la Sabana de Bogotá ha sido casi completamente sustituida por cultivos, potreros y urbanizaciones. El último relicto de esta vegetación es un pequeño bosque (ca 10 ha), ubicado en la Hacienda Las Mercedes en el borde norte de la ciudad de Bogotá. El tamaño reducido y aislamiento del bosque, agravado por el crecimiento descontrolado de vegetación invasiva (lianas y zarzamora silvestre) ha generado la pérdida de muchas especies. Sin embargo, en los últimos años el bosque ha sido objeto de acciones de rehabilitación y actualmente la zona está inmersa en una reserva en donde se prevén programas de restauración más amplios. Con el objetivo de evaluar los cambios en la comunidad de aves para estimar los efectos de las acciones de restauración, se registró la avifauna presente en 2001-2002 y en el 2014, mediante registros visuales y auditivos en puntos fijos en el bosque. En el primer censo se encontraron 27 especies de bosque y en el segundo 30, y las abundancias relativas de por lo menos la tercera parte de ellas también aumentó en los 13 años, indicando un resultado positivo en la recuperación del bosque. Los resultados resaltan la capacidad de recuperación de los ecosistemas degradados y la importancia de continuar con las acciones de restauración en el área de reserva.
