It was studied vegetal remainders into four mountain areas: Serra de Bodopitá (Area1), Serra de Bodocongó (Area 2), Serra do Monte (Area 3) and Serra do Canoió (Area 4) located in paraiban Cariri. The study aimed at determines the phytossociolical parameters and for this was used the program Mata Nativa 2. It was also calculated the indexes of Shannon, Pielou equability, diversity of species and families. From the 2972 sampled individuals, 633 belonged to Area 1, 602 to Area 2, 908 to Area 3 and 829 to Area 4. All of them were distributed in 54 species belonged to 25 botanic families. It was observed that the families Fabaceae and Euphorbiaceae had the largest number of species and individuals and after them Cactaceae, Anacardiaceae and Apocynaceae. The Shannon indexes values in Areas 1, 2, 3 and 4 were respectively 2.65; 2.93; 2.35 e 2.59 nats.esp.-1 . The founded densities were 3165 individuals.ha-1 in Area 1, 3010 individuals.ha-1 in Area 2, 4540 individuals.ha-1 in Area 3 and 4145 individuals.ha-1 in Area 4. The four areas had the same species with the most importance values being them: Caesalpinia pyramidalis, Aspidosperma pyrifolium, Bauhinia cheilantha, Piptadenia stipulacea.
