Analysis of Deforestation and Regeneration Processes in Conservations Units Belong to Ribeira Valley – SP/PR, Brazil Through Sensing Remote Images Classifications
Main Article Content
Abstract
The Ribeira Valley, localized between two important states of Brazil: São Paulo and Paraná, presents approximately 80% of the most preserved remnants of Atlantic Forest. Several physics and histories factors allowed the conservation of these remnants in this region. The topography, low soil fertility and water regime stand out as great allies for preservation of natural vegetation, in addition to the creation of Conservation Units. However, studies have pointed deforestation history in those protection areas. In order to relate the responsible processes for land-use changes, sensing remote techniques have been used in intention to investigate forest cover changes association. This work claimed to identify and map regeneration and deforestation areas in limits of Ribeira Valley’s Conservation Units in temporal serie from 1985 to 2017, comparing the results related to all region. Considering the forests covers distribution in Conservation Units, the forestall regeneration represented about 30% of total net gain, while the deforestation process was approximately 22% from 1985 to 2017. With exception of APA Quilombos do Médio Ribeira, APA Serra do Mar, PE Turvo and RDS Barreiro Anhemas, others Conservation Units had approximately zero deforestation. On the other hand, those areas were the same that forest gain calculated by regeneration were the biggest. Concludes that the creation of Conservation Units is important indeed to deforestation decrease range and favoring the forestal preservation of biome, allied the inspection actions.
