  1. Use prescribed burning on grasslands

    A randomised, controlled study in 1995-1997 in six tracts of tallgrass prairie in Melvern Wildlife Management Area, Kansas, USA (Applegate et al. 2002), found that Henslow’s sparrow were significantly less abundant in burned areas than in unburned tracts (1 bird/ha vs. 4); dickcissel abundance was similar in burned and unburned tracts (12 birds/ha). In spring 1995 four tracts were burned, in 1996 one was burned and in 1997 two were burned. In total, 22 Henslow’s sparrows (overall relative abundance 0.2 birds/ha) and 200 dickcissel (1.1 birds/ha) were recorded. Abundance was not correlated to tract perimeter length, or different distances to each other.
