Use prescribed burning on grasslands
A replicated, controlled study in 1992-1995 in native grass-sown Conservation Reserve Program fields in Riley County, Kansas, USA (Robel et al. 1998), found significantly lower bird nesting density in fields with spring (mid-April-May) burning in the year of the burn, compared to control fields (27 of 399 nests found were on burned fields vs. 372 on controls). Nest success was 22% on burned and 34% on unburned fields. Average bird abundance on burned fields (year of burn) was6 birds/km of transect vs. 9/km on unburned fields. Species richness was similar (12-21 burned vs. 10-19 unburned).
