Densidad Y Diversidad De Invertebrados Terrestres Con Fines De Restauración De Zonas Degradadas En El Municipio De Acacías - Meta.

Abstract

He was the evaluation of the effect of the planting of three species forestry foreign (Gmelina arborea, Acacia mangium and eucalyptus pellita) on the density of earthworms and biodiversity of edafofauna. The study was carried out on a farm with soils affected by human activities such as agriculture and livestock in the town of Acacias Meta Department. For the analysis experimental is used four treatments, three corresponding to crops forest and a forest riparian rather intervened. Each forest species was planted on one hectare with similar conditions of moisture, light and stocking density. TSBF technique indicating the extraction of the soil sample as a block of land (monolith) of 30 cm depth was used with respect to the collection of terrestrial invertebrates. This is subdivided in 4 different strata, being each an of these divisions or depths by Monolith taken as a unit of response, so is took 16 samples by treatment, 64 samples by each time (wet and dry) for a total of 128 samples. Each of the samples are analyzed both the diversity of edafofauna and the density of earthworms.
