This research was carried out at Parque Estadual do Espinilho, in Barra do Quaraí, Rio Grande do Sul State, Brazil, aiming to characterize the floristic, phytosociological structure and dynamics in Savana Estépica Parque. For such, within a permanent sample unit of 1 ha (100 m x 100 m), were identified and measured all individuals with diameter at breast height (DBH) ≥ 10 cm. The floristic is made up of Prosopis affinis, Prosopis nigra, Acacia caven and Scutia bixiflora, which presented a density of 141 and 145 individuals per hectare in 2001 and 2009. The mean annual increment was 0.027 cm ha-1 year-1, with ingrowth and mortality rates of 0.36% per annum. By the presented results, we may conclude that this vegetation is stagnant.
