Abstract Anthropogenic fire is a worldwide event that affects many ecosystems and organisms. In Southern Brazil, grassland management with has been highly employed since the mid‐18th century. Although practice regulated by federal law (prescribed fire), there no detailed information about impacts of this on small, non‐volant fauna. We evaluated effect anuran species richness community composition in Brazilian areas have adopted for more than 15 years. Our results show burning practices lead to reduction richness. About 37% occur exclusively sites free fire. Sites low densities taller grass shrubs, which could reduce habitat availability some species. Nestedness turnover components beta diversity did not differ within between treatments, but was tendency nestedness organization burned sites, suggesting are subsample where absent. pointed out prescribed potentially negative effects diversity. These suggest changes vegetation, particular percentages shrub cover, affect suitability Therefore, communities tend become less diverse lack arboreal occurs. Portuguese available online material.
