Proposal for rehabilitation of low-altitude rainforest fragments on a metamorphic complex, Alejandro de Humboldt National Park

Abstract

A study was conducted in the Jaguaní River sub-basin in the La Melba conservation department of Alejandro de Humboldt National Park. The objective was to propose restoration of the Low Altitude Rainforest on a Metamorphic Complex. Eleven sampling units were established in the conserved forest and 30 in the poorly conserved forest, measuring 20 x 25 m2 over 30 ha, using simple random sampling. The species richness, composition, structure, diversity, abundance, and ecological importance index were determined. Statistical processing was performed using BioDiversity Pro software. Seventy-four species of woody spermatophyte plants were identified, grouped into 32 families belonging to 63 genera. The families with the highest species richness were: Rubiaceae, Melastomataceae, Sapotaceae, Lauraceae, Arecaceae, and Moraceae. This led to the proposal of restoration actions in the study area.
