5. Efeito do manejo de fogo sobre comunidades de aves em campos sujos no Parque Nacional das Emas, GO/MS, Cerrado Central / Effects of fire management on birds in Emas National Park, Brazil, Central Cerrado
Several studies have investigated the effects of natural fires on Cerrado birds. However, avian responses to fire management have not been examined. We compared birds found in firebreaks (fire managed areas) and in fire unmanaged grasslands, in Parque Nacional das Emas, Central Brazil. This is the first study to evaluate the effects of prescribed fire on the
