The genus Eugenia presents one of the most important in Myrtaceae family, expressing a potential nutritional high and in drugs obtaining. The plants are resist and resist disease, their hardwood has been used to produce posts, stakes, poles, firewood and charcoal. The objective of this present work was to conduct a survey of the population structure of Eugenia sp. was conducted in caatinga area, located in the municipality of Caturité, PB. Were sampled Forty plots of 10x20 m, totaling a sample area of 8.000 m². All shrub-tree individuals were inventoried by the taking the ground level diameter (DNS), height and number of tillers. The vegetation structure was evaluated by basal area, absolute density, absolute frequency and aggregation index of the species. A total of 741 individuals of Eugenia sp. Distributed in four vegetation mosaics with a history of different uses, which were conventionally approached as: A I = Abandoned quarry area; A II = Bottom of the valley; A III = Conserved Area and A IV = Capoeira Area. Area I presented a total of 92 individuals sampled in the 10 experimental plots (DA = 460), where in this environment the species tended to cluster, Area II presented 124 individuals (DA = 620) and the McGuines index expressed that in this environment the species finds grouped. In Area III, 480 individuals were sampled with an absolute density of 2,400 ind. ha-1 grouped. The density of Eugenia sp. Was performed descriptive statistical analysis. It is different in vegetation mosaics due to the history of land use in the studied areas. The largest number of individuals of Eugenia sp. is concentrated in the conserved area showing aggregation pattern. In all areas of study, individuals have low stem diameter, expressing the importance of the species in the regeneration of disturbed areas. In the quarry area are the individuals with higher height.
