TITLE:

FLORISTIC AND PHYTOSOCIOLOGY IN TWO AREAS UNDER DIFFERENT ANTHROPIC PRESSURES IN THE BEACH OF ALCOBAÇA-BA

SUMMARY:

Brazil is one of the countries with the greatest diversity of flora in the world, the Atlantic Forest being the Brazilian biome with the largest number of species of Angiosperms. The Atlantic Forest is also a global biodiversity hotspot due to its high level of endemism and high degree of fragmentation. The restinga is one of the ecosystems considered to be associated with the Atlantic Forest, being formed by a group of physiognomically distinct floristic and plant communities. The main objective of this work is to analyze the composition and structure of the Restinga vegetation in two areas with different stages of conservation (conserved x degraded) in Alcobaça-BA, aiming at conservation actions for the plant biodiversity of the Alcobaça restinga. For this, the floristic survey is being carried out through monthly collections during a year with the purpose of sampling during all seasons of the year, using the walking method and the phytosociological analysis is being carried out by the line intercept method, where it is demarcated 10 lines parallel to each other in the eastwest direction, with 10 centimeters of distance and length each. The collection, treatment and herborization procedure is being followed through the techniques and protocols described in collection and herborization manuals. Samples available in other herbaria will also be analyzed. The identification is being carried out with the support of identification keys, comparison with samples from the GCPP Herbarium at UFSB and the virtual Herbariums at Reflora. The analyzes will be carried out using descriptive statistics for floristics and the phytosociological parameters will be carried out using FITOPAC 2. The comparison of the plots and areas of the restinga are being carried out, using the Sorensen index and the average association method Un -Weighted PairGroup Method using Arithmetic Averages (UPGMA) for grouping. So far, 80 individuals have been sampled in 10 plots and 2 species of the restinga. The richest family is Allagoptera arenaria (N=56; 70%), followed by Cyperaceae scleria (N=16; 20%) and Neoregelia cruenta (N=8; 10%). It is expected that the results found will provide subsidies for the understanding of the conservation of biodiversity in the restinga of Alcobaça-BA and help in the formation of a proposal of uses of native species of the restinga, contributing to the knowledge of the flora of Bahia and for future actions of conservation in the region.
