Manejo agroecológico do ecossistema pastoril: impactos sobre a comunidade de plantas espontâneas

Abstract

This paper aim to assess the implementation and establishment of a Silvopastoral system under agroecological management. For this reason, were used the phytosociology to compare the presence of spontaneous plants over a two-year measurement and data collection. Initially they were planted two tree species: Moringa oleifera and Gliricidia sepium, the legume family. Experiment consisted of four paddocks of 100m x 100m (1ha): Piq1 (Moringa); Piq2 (Moringa + Gliricidia); Piq3 (Gliricidia); Piq4 (Witness). a solo collection and phytosociological analysis of the occurrence of spontaneous was carried out in order to observe the species with the highest importance value (VI). Spontaneous spread evenly between the pickets, so it is necessary to deepen the studies on these species to understand if they cause changes in the pastoral system. The aim of this data, compare the development of the implementation of Silvopastoral system through the study of volunteers, to outline the main difficulties of the system establishment. Plants during the successive evaluations demonstrated decreased, but mainly increase both the Relative Density as the Relative Frequency therefore in the sixth. This indicates that some species thrive in terms of individuals (biomass) and other spatially over the area. It was also felt that this SSP handled lately, without the presence of animals, allowed a more intense emergence of spontaneous plants.
