  1. Use prescribed burning on pine forests

    A site comparison study in the winters of 2001-2002 at three pine savanna sites in southeast Louisiana, USA (Bechtoldt & Stouffer 2005), found that wintering Henslow's sparrow Ammodramus henslowii abundance was significantly higher in areas burned the preceding growing season (average of 3 birds/ha) than in areas burned two or three years previously (1 bird/ha). Eight areas were burned once in May-August 1999-2001. There was a trend for decreasing sparrow abundance with time since burn: 1.0/ha in areas burned one year previously, around 0.7/ha in areas burned two years previously and 0.2/ha in those burned three years previously. Of vegetation characteristics measured, average seed abundance (which decreased with time since burn) was the best predictor of sparrow abundance.
