Abstract: Abstract Fragmentation creates heterogeneous landscapes with different interactions and trajectories. In this scenario, the understanding in how forest fragment sizes influence forest species patterns can lead the way for biodiversity management and conservation in agricultural landscapes. The aim of this study was to compare the density and the diameter distribution of Bertholletia excelsa, Carapa guianensis and Cedrelinga cateniformis among fragments of different sizes, located at the Agro-Extractivist Settlement Project Praialta Piranheira, Pará State, Brazil. Data were collected from adult and sapling trees in six forest fragments. Adult and sapling density was compared among fragment sizes by the Mann–Whitney test, while diameter distributions were compared by a summary statistic calculated using the scores of a PCA produced with the results of the binomial logit model between tree DBH and the cumulative DBH proportions. The density of adult trees of three species is similar among different-sized fragments. Only the saplings of C. cateniformis showed a significant difference in density among fragment sizes. The DBH distribution of adults, for all three species, seems to also not respond to fragmentation, since the differences in the DBH distribution curves among fragments were large. The results of this study suggest that in areas established for agroextractivism, all fragments (large and small) no longer have sustainable populations (except only one C. guianensis population), probably due to anthropic pressure exerted by agroextractivism. So, it is important to ensure the structural and environmental quality of the forest fragments for the conservation of the species.
