Interactive key of arboreal species in seasonal forests of Southwest of Bahia

Abstract

The seasonal forests are phytophysiognomies of the Atlantic Forest biology most threatened, mainly, by the pressure exerted by agribusiness pressure and the process urbanization process. In this scenario, the knowledge of its structure and, mainly, of its floristic composition, are fundamental for the processes of conservation and preservation of natural resources. In order to support the process of species identification, this work had as objective to make an interactive key of tree species located in seasonal forests of the Southwest of Bahia. In the making of the key were excluded the species with less importance and equal to one individual per hectare in the respective surveys. For the preparation of the dendrological key it was necessary a survey of the morphological characteristics of the leaf and the thin branche, taking into account its variations, as well it is presence or default. The data was released on the Xper³ online platform. The consistency of the database was analyzed through the tool “checkbase”. A total of 177 species were used, 62 of the Leguminosae family. The key is available on the Xper³ platform for free access, it is efficient and simple to use. The key contemplates any species in several surveys carried out in Bahia and, can also be used for Seasonal Forests in other States.
