The ecological impact of cattle grazing on Brazilian savannas is poorly known. This study aimed to evaluate vegetation structure, diversity, and fuel load in savannas under rotational grazing. We studied three adjacent, fire-excluded savanna fragments in Central Brazil: one subjected to rotational grazing, one excluded from grazing for 2.5 years, and one ungrazed. For vegetation sampling, we used the line-point intercept method. Fuel load was quantified by measuring the dry mass of necromass, li
