Resumo: | The objective of this study was to adjust and select probability density functions that describe the diametric distribution of Poincianella bracteosa Tul, Mimosa ophthalmocentra Mart. ex Benth e Manihot carthaginensis subsp. glaziovii (Muell. Arg.) Allem species, and for this species as whole, which occured in Caatinga biome, in the municipality of Floresta, in the semiarid region of Pernambuco state. The study was conducted in an area with disturbance history with approximately 10 ha, where it was installed 20 plots (20x20m), in a symmetric way, where all the trees with circumference at the breast right (CBH) ≥ 6cm were identified and their diameters and heights were measured. It was tested the probabilistic functions such as: Weibull 3 parameters, Jonson’s Sb, Normal, Log-nomal, Gamma, Beta and Meyer. A class interval of 2 cm was used and Kolmogorov-Smirnov test was used as the selection criterium. It was found that the Weibull 3 parameters was the best function described the diametric distribution for Mimosa ophthalmocentra e Manihot carthaginensis. For Poincianella bracteosa Johnson’s Sb was the ideal one. The existence of strong disturbance observed in the study area, is explained by a unimodal distribution, reflected in the three species, so that the area deserves due attention so that this process ceases. |

Arg.) Allem e para o conjunto de espécies lenhosas ocorridas em uma área de Caatinga, no município de Floresta, semiárido pernambucano. O estudo foi realizado em uma área com histórico de perturbação com aproximadamente 10 ha, na qual foram instaladas 20 parcelas de (20 x 20 m), de forma sistemática. Os indivíduos lenhosos com circunferência a altura do peito (CAP) ≥ 6 cm, foram identificados botanicamente e tiveram seus diâmetros e alturas mensuradas. Foram testadas as funções probabilísticas de Weibull 3 parâmetros, Sb Johnson, Normal, Log-normal, Gamma, Beta e Meyer, utilizando-se um intervalo de classe de 2 cm e o teste de Kolmogorov-Smirnov foi empregado como critério de seleção. Verificou-se que a função de Weibull 3 parâmetros, foi a que melhor descreveu a distribuição diamétrica de Mimosa ophthalmocentra e Manihot carthaginensis, além de melhor descrever também o conjunto total de espécies. Para Poincianella. Bracteosa, a função ideal foi Sb Johnson. A existência de forte perturbação, observada na área de estudo, é explicada pela distribuição unimodal, refletida nas três espécies, portanto, a referida área merece devida atenção para que tal processo cesse.
