Diferenças na composição florística entre a borda e o interior de um remanescente urbano de Mata Atlântica do 19° Batalhão de Caçadores (SSA-BA)

Abstract

The process of deforestation in the humid tropics is one of the major threats to biodiversity. The remnants of vegetation located in the city of Salvador, include among other formations, remnants of Atlantic rainforest that are important refuges for native fauna. This study had the intention of characterizing the floral composition of the remaining fragment within the area where the 19th Battalion of Salvador/Bahia is located. The purpose of which is to support future conservation measures. The activities were conducted in January, March, April and May, through fortnightly collections by walking asymmetrically through the fragment and its border areas. For each individual plant in blossom or bearing fruit, fertile branches were collected, fixed in 70% ethanol and herbalist for later identification of species. In the study area 8 species were recorded, distributed in 68 genera, members of 40 families. The most representative families in numbers of species were the Fabaceae and Solanaceae. Although this biome is composed of anarboreous/shrub vegetation size, in this study herbaceous habit was the prevailing habit.
