  1. Restore or create grasslands

    A replicated controlled study in the breeding seasons of 2000-1 in two restored-mine grasslands and two control (unmined) grasslands (8-18 ha) in Kentucky, USA (Monroe & Ritchison 2005), found that Henslow’s sparrow territory size was generally smaller on restored grasslands (on 1 May, 0.29 ha/territory for 25 nests on restored sites vs. 0.34 ha/territory for 18 nests on control sites; 15 July: 0.33 ha/territory for 25 nests vs. 0.45 for 17). Average clutch size (3.8) and average number of fledglings per nest (of 48 nests, 28 fledged at least one young) were similar between sites. More insect prey was present on the reclaimed sites.
