FITOSSOCIOLOGIA E ESTRUTURA DIAMÉTRICA DE UM FRAGMENTO DE CERRADO SENSU STRICTO, GURUPI - TO.

Abstract

Thisaimed at carrying a phytosociological survey and determine the diametric structure of a cerrado ‘’stricto sensu’’. This study was conducted in Gurupi –TO, in the UFT Experimental Farm at Gurupi Campus, being the studied area inside a legal reserve located under the geographic coordinates 11”77’30.5 S e 49”05’62.9 W. Five plots of 20x50 m, 10 m away from each other, making 5000 m² or 0,5 ha of sampled area were installed. Inside this area all shrub-arboreal individuals with CAP ≥10 cm were sampled. A total of 2128 individuals were sampled, with 2062 living and66 standing dead, over 110 species, 42 families and 86 genera. The average height was of 7, 23 m, mean diameter of 6,87 cm and basal area of 10,88 m². The Shannon diversityindex (H’) has 3.65 and the Pielou evenness (J’) of 0,775.It was observed the presence of the diametric distribution pattern present in this inverted J plant community.
