Phytogeographic classification of Caatinga in a Sertaneja Depression environment in the municipality of Taboleiro Grande/RN
Floristic survey; Caatinga; vegetation.
The need for knowledge about the caatinga and floristic relations becomes increasingly important, as there is still a scarce number of works on these topics. For this reason, the present work aimed to carry out a floristic composition and phytogeographic analysis of the vegetation of Taboleiro Grande/ RN, a municipality that is located in the sertaneja depression (Latitude: 5° 55' 44'' South, Longitude: 38° 2' 47 '' Oeste) where a floristic survey was carried out, adopting the plot method of Mueller-Dumbois and Ellenberg (1974). In which 20 units were selected for the sample of a transect measuring 20 x 20m distributed randomly, where 1,509 individuals were found distributed in 15 families. The family with the largest number of individuals was Fabacea with 9 individuals, namely Anadenanthera colubrina (Angico), Peltophorum dubium (Canaflistula), Cenostigma pyramidale (catingueira), Amburana cearensis (cumaru), Piptadenia stipulacea (white jurema), Mimosa tenuiflora (jurema preta), Bauhinia forficata (Mororó), Enterolobium contortisiliquum (monkey ear) and Libidibia ferrea (juca plant), the other families had only one species.
