A vegetação do campus da Universidade Federal de Sergipe: florística e fitossociologia

Abstract

The Campus of the Federal University of Sergipe is in process of physical expansion of its internal structure since 2005 and, consequently, more than 1100 young and adult trees have been suppressed. This circumstance led to the need to carry out this work, with the objective of analyzing the floristic composition and the phytosociological structure of the Campus. A census of trees (CBH ≥ 15 cm) was carried out throughout the university during the period from December 2014 to January 2015. The variables collected were: CBH, height and crown area. The parameters evaluated were Absolute Density (AD); Relative Density (DR); Absolute Dominance (DoA); Relative Dominance (DoR) and IVC (Coverage Value Index). A total of 2,382 individuals were enrolled in 26 botanical families, 76 genera and 96 species. Based on the number of individuals, according to their origin, it was obtained a percentage of 51.44% for the native and 48.56% for exotic. The species with the highest IVC was Clitoria fairchildiana R.A. Howard. The total crown cover of all individuals was equivalent to 16.85 ha and 40.86% of the total area.
