Use prescribed burning on grasslands Bird Conservation

A replicated study in the winters of 2006-2007 in four wiregrass Aristida beyrichiana-dominated prairie sites in south-central Florida, USA (Butler et al. 2009), found that grasshopper sparrow were six times more likely to be found if transects were burned within the previous 12 months. Sedge wrens Cistothorus platensis were more abundant in grassland with longer intervals between fires.
