The Cerrado region comprises the world?s most biodiverse savanna and the largest cultivated pastures for cattle
in Brazil. Forty percent of these pastures are unproductive or degraded, with bare soil and native vegetation
increasingly replacing exotic forage grasses. This study sought to investigate the regeneration of native vege-
tation in the pastures of the Cerrado and to evaluate the contribution of biophysical, land management, and
landscape attributes to this process. Across the Cerrado, we analyzed pasture plant communities and the attri-
butes of pasture management intensification, fire events, landscape native vegetation cover, and climate and soil
types of 93 active pastures and 15 abandoned pastures. For the abandoned pastures, time since abandonment was
an additional variable. On actively cultivated pastures, savanna regeneration varied from 0 to 70%, with a di-
versity of herbs and woody species. Pasture management was the main predictor of savanna regeneration on
cultivated pastures. On abandoned pastures, time since abandonment was the main predictor. Exotic grass cover
had a strong negative relationship with savanna regeneration and they were present even in pastures abandoned
for 44 years. Our study reveals the potential of natural regeneration of the Cerrado and its particular predictors.
The occurrence of pastures with high natural regeneration indicates that national policies can promote native
vegetation restoration and silvopastoral systems with predictable, low cost implementation. MenosThe Cerrado region comprises the world?s most biodiverse savanna and the largest cultivated pastures for cattle
