Abstract

VARGAS, William. A brief description of the vegetation, with special emphasis on the intermediate pioneers of the dry forests of La Jagua, in the upper basin of the Magdalena River in Huila. Colomb. for. [online]. 2015, vol.18, n.1, pp.47-70. ISSN 0120-0739.  https://doi.org/10.14483/udistrital.jour.colomb.for.2015.1.a03.

Information on the flora of the dry forests of southern Huila province was revised, with emphasis on intermediate pioneer species that can support processes of ecological restoration and conservation of biodiversity, these data were compared with those obtained in the field over the past 30 years. According to literature, 203 intermediate pioneer species distributed in 123 genera and 45 botanical families were identified for Huila, while for La Jagua field data recorded 155 species grouped in 111 genera and 45 families among which Leguminosae, Rubiaceae, Euphorbiaceae, Malvaceae, Melastomataceae and Moraceae are the most important families. The main types of hedges in the landscape of La Jagua are described, with notes on major plant species, conservation status and representative fauna. A list of 155 intermediate pioneer species is proposed, with the most important attributes for use in processes of conservation and ecological restoration of dry forests in the region. This type of species is key in generating habitat, connectivity, resources for wildlife and production of resources such as firewood and wood for communities, within a model of landscape management tools.
