Characterization and evaluation of permanent preservation areas in the UFRB Campus, Cruz das Almas, Bahia.
The forests and other native vegetation formations of the country are a good of common interest to all inhabitants and enable the exercise of the right of ownership and its use. Areas of Permanent Preservation include all forms of native vegetation located on the banks of water bodies, located on hilltops and steep slopes with a declivity greater than 45°C. This study aimed to evaluate, identify and characterize the permanent preservation areas around the sources of the Campus of the Federal University of Recôncavo da Bahia - Cruz das Almas. The areas near the sources were characterized and evaluated based on the characteristics and the fragility of the landscape, being observed the origin and degree of conservation of the sources; the stage of regeneration of ciliary vegetation; use and occupation of the areas, as well as any other anthropogenic changes. In a total of 43 sources evaluated, 16 were classified as punctual and 27 diffuse. According to their state of conservation they were found two preserved, seven disturbed and 34 degraded. Among the major disturbances are the presence of invasive plants, the presence of domestic animals and garbage. In 76.7% of the areas around the sources in terms of their regeneration stage do not fit the definitions of the current legislation and the existing small fragments are disturbed and are isolated, which indicates the need for a plan for restoration and management of these areas.
