ESTUDOS BOTÂNICOS APLICADOS AO DESENVOLVIMENTO SUSTENTÁVEL: UTILIZANDO DADOS DENDROMÉTRICOS, FITOSSOCIOLÓGICOS E DO INVENTÁRIO FLORÍSTICO

Abstract

The Caatinga Biome is equivalent to 11% of the national territory. Extractivism has always been an intense activity in northeastern Brazil. The consequences of this predatory extractive model are felt mainly in the renewable natural resources of caatinga. Thus, unrecoverable losses in floristic and faunistic diversity, acceleration of erosion processes and decline of soil fertility and water quality by sedimentation are already observed. What is recommended is sustainable management, so that plants and animals can reproduce satisfactorily and in quantities that allow the self-recovery of the ecosystem. The present work consists of a presentation of the study conducted by Silva et al.(2013), which is entitled Sustainable Forest Management Plan of caatinga in the central region of the NB, comparing it to existing bibliography, aiming to contribute as another source information about the biome. As a result, floristic inventory was obtained containing 2556 individuals distributed in 14 species, where the species with the greatest abundance was Catingueira (Caesalpinia pyramidalis Tul.). The phytosociologic data observed indicate that the horizontal structure of the vegetation is formed by 07 species totaling 80.53% of the frequency, 93.70% abundance and 95.39% of dominance. Through the total forest stock, it was possible to estimate the possible exploitation of 15 plots or Annual Production Units (UPAs) per year, totaling 58,198,883 st, where one payphone per year will be explored. The Sustainable Forest Management Plan presented viable alternatives for the management of natural resources of Caatinga, in addition to the generation of rents and job creation for the local population.
