Evaluación del estado sucesional de la ronda de la microcuenca alta de la Quebrada Grande, Municipio de San Antonio de Tequendama (Cundinamarca).

Abstract

As a result of deforestation, pollution, degradation and fragmentation of the ecosystem of the upper reaches of Quebrada Grande Otálora 2013, was triggered regeneration processes (secondary succession) have tended not to recover pre-existing conditions, which also have required tens or hundreds of years and they affect not only the plants but the companion birds, besides introducing higher soil amendments (Margalef, 1995); It is noteworthy that depending on the intensity of the disturbance and the nature of the ecosystems which dominate the area, the succession has taken an unexpected turn reaching the lost generation of native species and high value ecosystems for the region. This board paper the problem of loss of native species and ecosystems in the round of the Upper Basin of the Quebrada Grande located in San Antonio del Tequendama, at first a taxonomic characterization of plant and wildlife species were some groups available today and they can do an ecological retrospective system before processes human intervention, so it became known as was the system before the episodes of disturbance and how this current condition can be modified through the replacement of species through time and space. The research contributed to the knowledge of wild birds found in this area, given the conserved areas and processed for future decision-making, particularly for micro Quebrada Grande. On the information obtained and the bibliographical support databases that were found in the area and / or similar ecosystems major vegetation species and birds of the upper watershed of the Quebrada Grande were determined, leading to generate the definition of ecosystem reference. The system was evaluated through their fundamental ecological relationships through the identification of key native species, this generated a stress reading posdisturbio round high watershed.
