Abstract (en):
An experiment of ecological restoration was established in a landscape degraded by livestock. We studied cuttings and seedlings of Clusia multiflora, Hedyosmum sp., Meriania nobilis, Piper sp., Saurauia sp., Tibouchina lepidota, Tournefortia sp. and Weinmannia sp., based on the availability and importance of these species in the area. After 13 weeks the mortality of the cuttings was total, and for the seedlings it was of 50 %. To improve the adaptation of the species and to include several new ones, in the second phase of the experiment we rescued new 1m tall seedlings, and acclimated them in a nursery for three months. We also applied Aloe vera crystals to the new cuttings to facilitate their rooting. In this second phase, seedlings (95 %) of the species became established: Billia rosea, Bocconia frutescens, Fuchsia sp., Hedyosmum sp., Inga sp., Myrsine coriacea, Saurauia sp., Schefflera sp., Siparuna sp. The surviving cuttings (33 %) were the following: Brugmansia arborea, Brunellia sp. and Saurauia sp. In general, rescued seedlings showed high potential for establishment, and may well promote restoration processes.
Abstract (es):
Se estableció un experimento de restauración ecológica en un paisaje degradado por ganadería en San
Félix (Bello, Antioquia). Se estudiaron estacas y plántulas de Clusia multiflora, Hedyosmum sp., Meriania
nobilis, Piper sp., Saurauia sp., Tibouchina lepidota, Tournefortia sp., Weinmannia sp., por disponibilidad
e importancia en la zona. Después de 13 semanas la mortalidad de las estacas fue completa y fue del 50 %
para las plántulas. Para mejorar la adaptación de las especies e incluir varias nuevas, en una segunda fase
del experimento se rescataron plántulas de 1 m de altura y se aclimataron durante tres meses en un vivero.
También se aplicaron cristales de Aloe vera a las nuevas estacas para facilitar su enraizamiento. Las plántulas
establecidas (95 %) correspondieron a: Billia rosea, Bocconia frutescens, Fuchsia sp., Hedyosmum sp., Inga
sp., Myrsine coriacea, Saurauia sp., Schefflera sp. y Siparuna sp. Las estacas supervivientes (33 %) fueron:
Brugmansia arborea, Brunellia sp., y Saurauia sp. En general, las plántulas rescatadas mostraron un alto
potencial de establecimiento y bien pueden promover procesos de restauración.
