Análise fitossociológica e florística do bioma caatinga no município de Aparecida - PB.

Abstract

The present work has as porpose to realize out the phytosociological and floristic survey of the caatinga biome in the Municipality of Aparecida – PB. Two areas were chosen, one more impacted by the anthropic action in the Duas Lagoas site and one less in the Acauã Settlement, both in municipality of Aparecida with geographic coordinate "06 ° 40 '44.2" S and "38 ° 01' 13.6" W. The sample units were adopted by plots, with 10 in each of the areas with dimensions of 10 x 20 m and a distance of 50 m between each plot. All individuals were identified, with a circumference starting at 10 cm, made the CAB measurement, for that were used metric and PVC pipes, graduated in centimeters and meters. The floristic and phytosociological parameters were: diversity, density, dominance, frequency, importance value index and coverage. The analyzed data presented the following results: 8 families and 14 identified species, with predominance of the family Fabaceae and the species Croton sonderiamus Null. Arg. The Shannon-Wiener Index in the areas together was 1.87. Data were processed in the FITOPAC 2.1 program. It was proposed a calendar of the beehives with the months of the year and the material offered for the species of bees, such as: nectar, wax and pollen.
