  1. Use prescribed burning on coastal habitats

    A replicated, controlled paired sites trial in 1996-1998 on a salt marsh in Rockefeller State Wildlife Refuge, Louisiana, USA (Gabrey & Afton 2000), found that seaside sparrow Ammodramus maritimus numbers were lower on four burned plots than on unburned controls  in the breeding season after the burn (0-3 males/survey for burned areas vs. 7-12 for unburned). However, numbers were higher on burned plots the following year (16 males/survey vs. 8). Sparrow numbers were similar across plots in 1996, before burning, which occurred in 9-18 January 1997. Territorial male sparrows were recorded in April-July in 1996-1998 in each 250 x 250 m plot.
