Use prescribed burning on grasslands
In prairie grassland at Air Force Avon Park Range, USA, a replicated study in March-August 1997-1999 (Delany et al. 2002) found that Florida grasshopper sparrow Ammodramus savannarum floridanus reproductive success was significantly higher six months after burning (38% of 32 nests successful) than at 18 (14% of 35 nests successful) and 30 months (0% of 13 nests successful) after burning. Four prairie pastures (165-324 ha) were burned in December to mid-March on three year rotations. Sparrow territory density (up to 0.2 territories/ha) appeared unaffected by time elapsed since burning.
