Use prescribed burning on coastal habitats
A replicated, controlled study on Spartina marshland at Blackwater National Wildlife Refuge and Fishing Bay Wildlife Management Area, Maryland, USA (Almario et al. 2009), found no significant difference in overall predation rates of seaside sparrow nests between three plots burned in January-March 2002-2003 and three plots last burned in 1994 (37-41% of 130 nests in burned areas predated vs. 27-43% of 112 in unburned areas). In 2002, but not 2003, predation rates in the incubation period were higher for burned areas (35% of 51 nests) than unburned areas (13% of 45).
