Análise do componente arbustivo-arbóreo regenerante em área revegetada

Abstract

A species analysis was carried out with the objective of evaluating the structure of the vegetation in regeneration, therefore, the phytosociological parameters were related to the natural regeneration of a mineral extraction area in recovery, implanted in the Murtura Settlement, located in the city of São Luís, Mesoregion Norte Maranhense, Microregion of the Urban Agglomeration of São Luís. It is on the right bank of the BR-135, at km 18 towards São Luis / Estiva, 2 km. The individuals planted in 2016 and monitored in 2018 were sampled by the permanent plot method with dimensions of 10m x 10m to monitor individuals referring to the native species emerging from natural regeneration and planted. The phytosociological parameters determined were: Relative Density, Relative Dominance, Relative Frequency, Importance Value and Coverage Value, and Shannon and Weaver Diversity Index (H '). Ten (10) parcels were identified, one hundred and forty-eight (148) living individuals distributed in twelve (12) families and sixteen (16) species, and one unknown. The species with the highest Importance Value were Lecythis lanceolata with 26.09% VI, Anacardium occidentale with 13.70% VI, and Clitoria fairchildiana with 11.57% VI
