Grazing intensity manipulation can affect structure and botanical composition of the pasture. The objective of this research was to evaluate the effects of different forage allowances and different seasonal sequences of forage allowance (FA) on the species population dynamics in the rangelands of Campos Sulinos. The botanical composition evaluations were made in January 12th and July 17th, using BOTANAL method. Treatments were of different FA (kg DM 100kg-1 of live weight day-1): 8, 12, 16 all around the year; and different sequences of FA: 8 on spring and 12 at the rest of year (8-12); 12 on spring and 8 at the rest of year (12-8) and 16 on spring and 12 at the rest of year (16-12). The statistical design used was randomized blocks with two replications. The forage allowance led to changes in botanical and structural composition of vegetation. It can be inferred that the forage allowance variation on the vegetation had higher impact on smaller forage allowances.
