The aim of this study was to carry out a phytosociological and floristic survey of the caatinga biome in the municipality of Aparecida - PB. Two areas were chosen, one more impacted by anthropogenic action in the Duas Lagoas site and the other less so in the Acauã settlement, both in the municipality of Aparecida with geographical coordinates "06°40' 44.2" S and "38°01' 13.6" W.

The sampling units were plots, with 10 in each of the areas with dimensions of 10x20 m and a distance of 50 m between each plot. All the individuals with a circumference of 10 cm or more were identified and the CAB was measured using measuring rods and PVC pipes, graduated in centimeters and meters. The floristic and phytosociological parameters were: diversity, density, dominance, frequency, value of importance and coverage index. The data analyzed showed the following results: 8 families and 14 species identified, with a predominance of the Fabaceae family and the species Croton sonderiamus Null. Arg. The Shannon-Wiener Index for the areas together was 1.87. The data was processed using the FITOPAC 2.1 program.
