Abstract (en):
The ecosystems of Valle del Cauca have been transformed to a landscape with few and small fragments of forest. This study measured the mortality and recruitment rates, changes in structure, composition, and biomass storage of the vegetation in a one-hectare permanent plot in the El VÃnculo Regional Natural Park, Valle del Cauca, in 2009 and 2011. One thousand, seven hundred sixty-eight stems with DAP ⥠5 cm were registered, which increased to 1811 stems in 2011, comprising 52 species and 25 families. Fabaceae and Rutaceae were the dominant families. The species with highest IVI, basal area, and biomass contribution were Eugenia procera, Amyris pinnata, Pithecellobium lanceolatum, Guapira sp. and Guazuma ulmifolia. The annual mortality rate (Tm= 4,84%) was due to stem death of heliophilous species. The annual recruitment rate (Tr= 6,94%) showed the success in dispersal and establishment of animal-dispersed species. The tendency of the vegetation was to increase basal area and biomass. We conclude that the forest is in an early successional stage, shows no disturbance, and is a reservoir representative of the diversity of tropical dry forest.
Abstract (es):
Los ecosistemas del Valle del Cauca han sido transformados a un paisaje con pocos y pequeños fragmentos de bosque. Este estudio midió tasas de mortalidad y reclutamiento, cambios en estructura, composición y almacenamiento de biomasa de la vegetación en una parcela permanente de 1 ha en el Parque Natural Regional El VÃnculo, Valle del Cauca, en el 2009 y 2011. Se registraron 1768 tallos con DAP ⥠5 cm que aumentaron a 1811 tallos en el 2011, representados por 52 especies de 25 familias. Fabaceae y Rutaceae fueron las familias más dominantes. Las especies con mayores IVI, área basal y aporte de biomasa fueron Eugenia procera, Amyris pinnata, Pithecellobium lanceolatum, Guapira sp. y Guazuma ulmifolia. La tasa de mortalidad anual (Tm= 4,84%) se debió a la muerte de tallos de especies heliófilas. La tasa de reclutamiento anual (Tr=6,94%) reflejó el éxito en la dispersión y establecimiento de especies dispersadas por animales. La tendencia de la vegetación fue a aumentar el área basal y la biomasa. Se concluye que el bosque se encuentra en un estado sucesional temprano, no muestra perturbación y es un reservorio representativo de la diversidad del bosque seco tropical.
