Checklist of trees at the Sao Roque campus, Federal Institute of Sao Paulo

Trees are important elements of ecosystems, especially in Atlantic rain forest ecosystems. At the Sao Roque campus, Federal Institute of Sao Paulo, the arboreal flora comprises indigenous species of the Atlantic biome, as well as foreign species and cultivated angiosperms. The research focused on qualitative and quantitative analyses, generating a checklist of species and their botanical families. A total amount of 34 families (3 of Gymnospermae, and 31 of Angiospermae), and 72 species were observed. The most representative families in number of species were Fabaceae, Myrtaceae, Anacardiaceae, and Bignoniaceae. The occurrence of an arboretum of native species located at the Sao Roque campus contributes to a high number of indigenous plants. Although the number of species and families might reveal a relatively high rate of vegetal biodiversity, many individuals have been purposefully introduced, thus suggesting that the area should continue to be re-vegetated.
