This study analized the proportion of forestlands, shrublands and grasslands protected by conservation units in the State of Tocantins. The basis for this study was the land use and land cover map of Cerrado, produced by PROBIO and published in 2007. The legend of PROBIO´s map was grouped into forestlands, shrublands and grasslands. An area corresponding to 6.3% of Cerrado biome in the State of Tocantins is fully protected. Shrubland (42.8%) is the most protected formation, followed by grassland (37.1%) and forestland (18.8%). In several conservation units, only one formation is more protected than others. This is the case of State Park of Cantão (82.7% of forestlands), State Park of Jalapão (84% of grasslands) and the Monument of Petrified Trees of State of Tocantins (80.9% of shrublands). It is suggested that new conservation units should be created to protect more areas of forestlands, mainly dry forests and Cerradão.  aGrasslands  aPublic policy  aSavannas  aBiodiversidade  aCerrado  aPolíticas Públicas  aVegetação  aUnidade de conservação1 aSANO, E.
