  1. Mow or cut semi-natural grasslands/pastures

    A replicated study at a mine site in Ohio, USA (Ingold et al. 2009), in 1999-2007 found that ten of 99 (10%) Henslow's sparrows Ammodramus henslowii ringed on four unmown non-native grassland were recaptured, whereas none of the 15 birds ringed on four mown grasslands were recaptured. In total, 87% of ringed birds were caught on unmown grasslands. Experimental plots were established in 1999 and the mown plots cut in mid-April every year. birds were ringed in 2000-2007 and recaptured in 2001-2007.
