The objective of this study consists in evaluating seasonally the seeds production from forest fragments located in rural zone of Campo Verde, MT. This characterization occurred in terms of seed production and plant species richness. Three forest fragments characterized as semidecidual stational forest were selected. In each fragment five collectors were installed and made with PVC pipes (1 m²; nylon mesh of 0.001 m and 0.15 m depth of the bulge). The material was monthly collected, and the seeds were quantified, and separated according to the sort of dispersal, successional stage and form of life. It was determined the density, absolute frequency, diversity index and equitability. Altogether 3,622 seeds were collected, belonging to 74 taxa. The highest densities of seeds were observed during the months of September, October and November. Lianas Gouania sp., Fridericia speciosa, Heteropterys sp. and Distictella sp. responded with 55.95% of total collected seeds. From all the species that composed the seed rain, 74% are not dispersed by wind. However, when the amount of diaspores collected was checked, forms dispersed by wind were predominant, representing 76% of total. It may be cited as important arboreal taxons for reforestation in the region of Campo Verde, located at southeast of Mato Grosso: Tachigali rubiginosa, Siparuna guianensis, Nectandra sp., Cordia alliodora, Alibertia sp., Terminalia brasiliensis and Myrcia sp. These species should be targeted for more specific studies related to their potential for recovery of degraded environments, considering permanent preservation areas and legal reserves.
