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.
