The reproductive phenology of shrubs and trees in an area of Cerrado (Brazilian savanna) in the Mogi Guaçu Biological Reserve (22°10’S; 47°11’W) was studied from September 2009 to May 2013. In a 900 m2 transect, individuals were marked, and the total number of flowers and fruits was estimated monthly. The data were analyzed using circular statistics to determine the periods of most intense flowering and fruiting in the community, according to their dispersal modes. Flowering occurred between October and November. Fruiting was distributed continuously throughout the year, with r values up to 0.3. In the last period of observation, fruiting was more intense in December, probably due to zoochorous species. For the three main families, Myrtaceae flowering and fruiting occurred between August and September, Malpighiaceae flowering occurred in November and fruiting was between December and January, and Vochysiaceae flowering was in January and fruiting was in March. In general, a main characteristic of the community was the weak seasonality of its reproductive phenology. However, reproductive events tended to take place in the hottest months of the year.
