Abstract
Introduction. Tropical dry forests are one of the
most threatened ecosystems in the neotropic, and
are considered in Colombia to be one of the least
understood, and one of the most degraded and
fragmented ecosystems. Given this fact, the current efforts to preserve these existing relicts are not
sufficient and thus it is necessary to take actions to
reactivate their natural succession processes and
to connect isolated fragments of this ecosystem. At
La Pintada (Antioquia), a restoration project started
nine years ago in places with low grass coverage
by initially seeding various species typical of tropical
dry forests. Unfortunately, the restoration progress
was never monitored and the relative success of the
project is unknown. This research had an objective
to characterize and evaluate the succession process
that was produced by the ecological restoration.
Materials and Methods. Ten permanent 0.05 hectare plots were established for diametric structure
and flower composition of the vegetation measurements. Samples were taken from 694 trees of 33
different species. Results. The diametric structure
had an inverse J shape, which is very common in
the early stages of succession. Conclusions. An
apparently successful restoration process was observed considering that the restoration was made in
only grass covered areas and that by the time of the
study, common features of secondary succession in
tropical dry forests such as fast growing trees, colonizing shrubs and a discontinuous canopy with midsize isolated trees, were all present. Nevertheless,
the system must continue to be monitored in order
to take appropriate follow up actions to facilitate the
emerging succession process.
