Resumo: This study was carried out in an area inserted in the Savana-Estépica ecosystem, part of the bioma Caatinga, and it is located near the town of Campina Grande, State of Paraí­ba, Brazil. The aim of this study was to describe the floristic composition and the structure of the vegetation through floristic studies and forest inventory. It was studied eight sampling plots of 10 x 40 meters, where were measured all trees and shrubs with stem diameter at soil level > 2 cm and height > 100 cm. It was calculated the phytosociological parameters, indexes of Shannon (H"™) and Pielou equability (J). The predominant layer in the vegetation is the shrub, with heights ranging from one to two meters, and trees whose maximum height is of 5 meters. The total basal area was 2.94 m2.ha-1. The phytossociological study registered a low diversity of species (n=20). The Shannon"™s index was H"™=1.89 nats.ind-1. The species of highest value of importance were Mimosa tenuiflora, Ziziphus joazeiro, Croton blanchetianus, Poincianella pyramidalis, and Commiphora leptophloeos. The floristic study registered 65 species, among trees, shrubs, herbs, vines and epiphytes. Therefore, with the results it was concluded that the vegetation is in the initial stage of ecological succession with different degrees of human impact.

O objetivo desteestudo foi conhecer a composição florí­stica e a estrutura da vegetação através de estudo florí­stico e inventário florestal em oito parcelas de 10 x 40 m, onde foram mensuradas todas as árvores e arbustos com diâmetro ao ní­vel do solo > 2 cm e altura > 100 cm. Foram calculados parâmetros fitossociológicos, í­ndices de Shannon (H"™) e equitabilidade de Pielou (J). O estrato da vegetaçãopredominante é o arbustivo, com alturas variando entre 1 e 2 m, com presença de árvores emergentes, cuja altura máxima é de 5 m. A área basal total foi de 2,94 m2.ha-1. A fitossociologia registrou uma diversidade baixa de espécies (n=20), com o valor de Shannon H"™=1,89 nats.ind-1. As espécies vegetais de maior densidade foram Mimosa tenuiflora, Croton blanchetianus, Poincianella pyramidalis, Croton heliotropiifolius, Jatropha mutabilis e Piptadenia stipulacea. As espécies com maior valor de importância foram Mimosa tenuiflora, Ziziphus joazeiro, Croton blanchetianus, Poincianella pyramidalis e Commiphora leptophloeos. A florí­stica registrou 65 espécies, entre árvores, arbustos, ervas, lianas e epí­fitas. Com os resultados concluiu-se que a vegetação encontra-se no estágio inicial de sucessão ecológica com diferentes graus de antropização.Universidade do Estado do Rio Grande do Norte (UERN)2017-07-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion Peer reviewed Revisado por paresAvaliado pelos paresapplication/pdfhttps://periodicos.apps.uern.br/index.php/GEOTemas/article/view/786Journal Geotemas; Vol. 7 No. 1 (2017): Revista Geotemas; 71-83Revista Geotemas; Vol. 7 Núm. 1 (2017): Revista Geotemas; 71-83Revista Geotemas; v. 7 n. 1 (2017): Revista Geotemas; 71-832236-255Xreponame:Revista Geotemasinstname:Universidade do Estado do Rio Grande do Norte (UERN)instacron:UERNporhttps://periodicos.apps.uern.br/index.php/GEOTemas/article/view/786/694Copyright (c) 2017 REVISTA GEOTEMASinfo:eu-repo/semantics/openAccessDario, Fabio Rossano 2020-07-30T18:17:14Zoai:ojs2.periodicos.apps.uern.br:article/786Revistahttp://periodicos.apps.uern.br/index.php/GEOTemas/indexPUBhttp://periodicos.apps.uern.br/index.php/GEOTemas/oaigeotemas@uern.br||josielguedes@yahoo.com.br2236-255X2236-255Xopendoar:2020-07-30T18:17:14Revista Geotemas - Universidade do Estado do Rio Grande do Norte (UERN)false
