FITOSSOCIOLOGIA EM DIFERENTES SISTEMAS DE USO DA TERRA NA ZONA RURAL DE CAMETÁ (PARÁ, BRASIL)

Abstract

The phytosociological study is a tool that allows making several inferences about the flora of rural properties. This work aimed to carry out a phytosociological survey of different land use systems in a rural property in the Bosque Menino Jesus community, Cametá (Pará, Brazil). The study was carried out in three different productive systems: A1 - agroforestry system, A2 - monoculture of Piper nigrum (black pepper), A3 - agroforestry system implanted in a monoculture of P. nigrum. The frequency of occurrence, density, relative abundance and the indexes of diversity and equitability were evaluated. Twenty-six species were identified, distributed in 14 families, the most representative are: Fabaceae (7 spp.), Meliaceae (3 spp.), and Anacardiaceae (2 spp.). Piper nigrum was present in the three areas, being the most representative in terms of frequency of occurrence and abundance, mainly in areas A2 and A3. Among the study areas, A1 presents the greatest diversity with equitable distribution of species. In general, the phytosanitary status of the plants was good, with the presence mainly of grasshopper and ant. The results demonstrate the recent implementation of the agroforestry system and the increase in species diversity.
