Análise da cobertura vegetal e da diversidade florística na área do Lajedo da Salambaia, Cabaceiras – PB

Abstract

The Caatinga is a biome found only in Brazil and their main occurrence area is within the Northeast Region. Its meaning is of Tupi-Guarani origin and means "floresta branca" due to the tonality acquired by the vegetation during the dry season. Although it has high biodiversity, it is little known and studied by the scientific community, it is little known and studied by the scientific community, and suffers from human activities, being one of the altered biomes and threatened with extinction. Thus, there is the need to increase efforts and expand the number of surveys conducted among other initiatives that provide more knowledge about this type vegetal formation of brazilian exclusivity. This study aimed to survey the caatinga and analyze the vegetation and existing floristic diversity in some areas under the influence of Lajedo of Salambaia, Cabaceiras – PB. The methodology used it relied on the realization of linear transects of 50m x 2m, which were identified shrubby and arboreous individuals in an area of 0.5 ha. The rocky outcrops collaborate decisively to the occurrence of the species found in the study area, which is the exclusive occurrence of the Atlantic Forest, Amazon and Cerrado and wetter areas of Caatinga, based on the literature information and Botanical Garden site of Rio de Janeiro. The results indicate the presence of 1727 individuals, 86 species, two of them never before registered in Paraiba.
