             abstract = "Throughout decades the S{\~a}o Francisco River Basin (SFRB) has 
                         been explored in a disordered fashion. In order to change this 
                         scenario, a project conducted by the Environmental Zoning Division 
                         (IBAMA), as part of the Macro-Zoning of the SFRB, appointed 47 key 
                         conservation areas, based on biological aspects. The aim of this 
                         study was to improve this work with landscape structure analysis, 
                         intending to evaluate the fragmentation status of these important 
                         areas, within the Caatinga domain. The natural classes were 
                         extracted from the vegetation cover map of the Caatinga biome, 
                         prepared within scope of the PROBIO program. This map was used to 
                         calculate the following landscape metrics: total landscape area 
                         (TLA), mean nearest neighbor (MNN), mean patch size (MPS), number 
                         of patches (NUMP) and mean shape index (MSI). The values of each 
                         landscape metric were grouped in 5 classes (scores), which were 
                         summed providing a single score for each area. Based on these 
                         scores, the areas were classified upon its fragmentation status. 
                         Two of the 22 evaluated areas was classified as very well 
                         conserved, 6 areas as well conserved, 4 as fragmented, 6 as very 
                         fragmented and 4 as critically fragmented. We suggest giving 
                         highest priority to the critically fragmented that simultaneously 
                         present an extremely important biological value. To better 
                         understand the process that leads to biodiversity loss, studies of 
                         functional connectivity approach are at need. Nevertheless studies 
                         like the present one, observing only structural aspects, are 
                         helpful to guide some conservation strategies and to establish 
                         priorities in an environmental agenda.",
