Censo florestal de um fragmento urbano de Mata Atlântica no Campus-Sede da UFRPE

Abstract

The ongoing urbanization and expansion of cities, have resulted in profound modifications to the surrounding natural environments, significantly impacting biodiversity and ecosystems. In urban contexts, native vegetation fragments become essential for biodiversity preservation and enhancing the quality of life for inhabitants. The purpose of this study was to conduct a floristic census in an urban area situated in Zone I of the UFRPE Recife campus, through the collection of dendrometric data and georeferencing of all tree habit individuals, aiming to contribute to the dissemination of botanical and ecological knowledge and provide scientific data for future research in the area. Zone I, designated as the study site, was divided into four areas, referred to as Area 1, Area 2, Area 3, and Area 4, to facilitate data analysis. These samples were subsequently compared with other materials from the Prof. Vasconcelos Sobrinho Herbarium (PEUFR). For the construction of the floristic census, tree species with a height ≥ 2.5 m and DBH (Diameter at Breast Height) ≥ 10 cm were considered, as they already fulfill their urban role according to the objectives of this work. Among all the sampled species, Clitoria fairchildiana (sombreiro) had the highest representation, totaling 48 individuals identified within the study area, followed by Paubrasilia echinata, Tabebuia rosea, and Mangifera indica, with a total of 20, 19, and 18 specimens found, respectively. Based on the results, despite Zone I being a highly anthropized area due to its location and intense human traffic, the quantity of species surveyed proved satisfactory for an urban forest fragment, demonstrating a strong presence of native flora and a wide diversity of species.
