Propuesta metodológica de restauración para la vegetación riparia a partir de la variación de la composición florística en diferentes épocas climáticas del humedal Torca-Guaymaral

Abstract

Introduction. 2014-2015 El Niño Southern Oscillation evidenced at regional and national levels had impacts in hydric ecosystems as well as in vegetal coverages associated to the same. Objective. With the objective of establishing the relation between riparian vegetation variation and climatic variability in urban Torca-Guaymaral wetland, floral characterization of riparian vegetation associated to this strategic ecosystem was carried out for the north border of Bogota city. Later on, a restoring methodological proposal focused on reestablishing the structure and function of riparian vegetation through assisted succession was posed. Materials and methods. During 2014-2015, there were samplings in two climatic epochs (humid and dry) in 21 units of sampling in order to evaluate vegetal coverages with a higher structural development, composition, and richness. Results report that there is a high presence of invading species (Ulex europaeus and Genista monspessulana), which has generated a total elimination of native species and a lessening in diversity of the wetland, which makes it impossible for other species to arrive at this place. Results. Additionally, a positive relation between the increase in temperature and colonization was found. Likewise, a high dominance in area and abundance of invading species have been reported, which makes it difficult to recover the area with native species and reduces ecosystem services of the wetland. Conclusion. This study poses a methodology for recovering riparian vegetation of the southwest sector of TorcaGuaymaral wetland, bearing in mind conflicts in the area: In this study, assisted vegetal succession, management of invading species and planting of new species are involved.
