Estrutura fitossociológica de um remanescente de floresta estacional semidecidual ribeirinha da fazenda experimental da Universidade Federal da Grande Dourados

Abstract

This study aimed to characterize the phytosociological structure in a remnant of riverside semideciduous forest located at the Experimental Fann of Universidade Federal da Grande Dourados, to support management actions and recovery. Were allocated 13 contiguous plots of 400m z, being sampled all individuals with circumference at breast height greater than or equal to 10 cm. The phytosociological survey resulted in 23 families, 45 genera and 56 species. The Shannon diversity index (H ') was 3.172, and equability (J') was 0.788. Most of the species are early successional which shows the degree of human influence that is the fragment; of dispersal was the most frequent zoochory. The results of this work contributed to the knowledge of the flora of South Mato Grosso, reinforcing the need for conservation of these riparian forests and providing grants for restoration projects of degraded areas around the regional rivers.
