Use prescribed burning on grasslands
A replicated study in the winters of 2002-2003 in coastal prairie at Brazoria National Wildlife Refuge, Texas, USA (Baldwin et al. 2007), found no significant difference in average number of bird species in five plots one year after burning, compared to plots two or three years after burning. Three rarer species (sandhill crane Grus canadensis, Sprague's pipit Anthus spragueii and grasshopper sparrow) were only observed in first-year burn plots. Of the four commonest species, Le Conte's sparrow A. leconteii was significantly more abundant in second-year than third-year burn plots, savannah sparrow more so in first- than second- or third-year burn plots, and sedge wren Cistothorus platensis more common in second- and third-year than first-year burn plots. No significant differences were found for swamp sparrow Melospiza georgiana.
