Análise da diversidade e da abundância florística da vegetação do Jardim Botânico Universitário da Universidade Eduardo Mondlane

Abstract

This study aimed to analyze the diversity and floristic abundance of the vegetation in the University Botanical Garden of Eduardo Mondlane University. For phytosociological sampling in the University Botanical Garden (JBU), 14 transects oriented in an east-west direction were used. Ten 10 × 10 m (100 m2) plots were installed within each transect. In total, 108 sampling units were defined, divided into 30% for the intact vegetation area and 70% for the maintenance area. Within the 10 × 10 m plots, the diameter at breast height (DBH) was measured. For herbaceous vegetation sampling, a 1 × 1 m (1 m2) subplot was installed in the center of each 10 × 10 m (100 m2) plot, duly georeferenced. In the case of individuals with tillers, each tiller was counted as a distinct individual. Seedlings and juveniles of the woody and herbaceous components were also recorded, identified through visual observation, using supporting literature, and considering morphological attributes. In total, 6,396 individuals belonging to 221 species were recorded, distributed across 70 families. The most represented families were: Fabaceae, Euphorbiaceae, Poaceae, Malvaceae, Apocynaceae, Asteraceae, Rubiaceae, Menispermaceae, Asparagaceae, Anacardiaceae, Phyllanthaceae, Lamiaceae, Bignoniaceae, Amaryllidaceae, and Verbenaceae. The DBH pattern of the Botanical Garden's vegetation was inverted J-shaped. (TRADUÇÃO NOSSA)
