Resumo: | The Caatinga Biome includes a predominantly xerophilic flora, whose characteristics are connected to the conditions in the region. It includes activities that affect directly the aspects of the caatinga, one of which is livestock. Therefore, this study aimed at evaluating the Phytosociology of the arboreal-shrubby component, as well as ecological indicators, in two areas of Caatinga with different history of use, in the drylands of the state of Paraiba. For this purpose, two locations belonging to a rural area of Brejo do Cruz-PB were considered one destined to the creation of cattle for over 20 years and the other without activities for 10 years. Thus, 40 lots of 25 x 10 m (250 m²) were installed at those areas, in which individuals were sampled according to their family, genus and species, and phytosociological parameters were analysed. The evaluated indicators were: natural regeneration, litter and entomofauna. The results showed that the two areas presented similar patterns, regarding phytosociology and diversity, where Poincianella bracteosa, Mimosa tenuiflora and Aspidosperma pyrifolium are the main species. As for the ecological indicators, the natural regeneration and Entomofauna both presented similar results for the areas, while the leaf litter presented a significant difference between the areas, indicating a higher value for the preserved environment. However, the areas showed similar patterns, indicating that the animal intensity did not exert any difference in the considered period. |

Assim, o presente estudo teve como objetivo avaliar a Fitossociologia do componente arbóreo-arbustivo, bem como indicadores ecológicos, em duas áreas de Caatinga com históricos diferentes de uso, no Sertão Paraibano. Para isso, considerou-se duas áreas pertencentes à uma zona rural de Brejo do Cruz-PB, uma destinada à criação de bovinos há mais de 20 anos e outra sem atividades há 10 anos. Com isso, foram instaladas 40 parcelas de 25 x 10 m (250 m²) nas respectivas áreas, no qual foram amostrados indivíduos quanto à família, gênero e espécie e feita análise dos parâmetros fitossociológicos. Os indicadores avaliados foram: regeneração natural, serapilheira e entomofauna. Os resultados mostraram que as duas áreas apresentaram padrões semelhantes em relação à fitossociologia e diversidade, tendo como principais espécies Poincianella bracteosa, Mimosa tenuiflora e Aspidosperma pyrifolium. Quanto aos indicadores ecológicos, a regeneração natural e Entomofauna apresentaram resultados semelhantes para as áreas, enquanto a serapilheira apresentou diferença significativa entre as áreas, apontando maior valor para o ambiente conservado. Contudo, as áreas apresentaram padrões similares, indicando que a intensidade animal não exerceu diferença no período considerado.
