Classificação fitogeográfica da caatinga em ambiente de depressão sertaneja no município de Taboleiro Grande/RN. Orientador: Dr. Diógenes Félix da Silva Costa. 2023. 102f.

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 from 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 Fabaceae 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. The species that had the greatest representation was the croton known as Marmeleiro. Thus, the SAVI index was also applied, where the values ranged from 0.196 to 0.764, which shows the presence of exposed soils and for the Shannon diversity indices, it showed low species diversity. This makes it clear that it is important to study the regeneration of the caatinga to think about strategies for sustainable use of the environment.pt-BRAcesso AbertoCaatingaLevantamento florísticoVegetaçãomasterThesisCIENCIAS HUMANAS::GEOGRAFIA
