Histórico de uso e ocupação das terras da Serra da Jibóia – Ba como subsídio à criação de uma unidade de conservação

Abstract

The Atlantic Forest is the one of the richest region in biodiversity in the world; in the Brazil it initially had 15% of its entire area. In the last thirty years, the fragmentation and suppression have imposed seriously changes to the most part of the Atlantic Forest, currently, have about 8,5% of the forest remains above 100 ha, however, summarizing all of the native forest fragment above 3 ha, have only 12,5% of the original area. The ecological corridor implementation has become an essential part to insure the protection in in the long term of the biodiversity. Serra da Jiboia is a mountaineer massive and more significant area of Atlantic Forest localized in the Recôncavo of the Bahia, which have some cities in its territory; Elísio Medrado, Santa Teresinha, Castro Alves, Varzedo and São Miguel das Matas. The analysis of the occupation soil became relevant due manners of the human have used the geographic. The GIS tool is the more used to realize that studies. The objective of this study was to do the occupational use of soil historic in the Serra da Jiboia through of the analysis of satellite images in four different periods. The resulted obtained showed that the class with the dominant cover in the all epoch was the pasture and agriculture that demonstrated little change over the 30 years, this has stagnated the remaining. The maps of permanent preservation area represent just 21,6% of the total forest. Deforestation process and fragmentation of the area did the Serra da Jiboia an isolated region from other Atlantic Forest remaining.
