Control predators not on islands for gamebirds Bird Conservation

A replicated study (Baines 1996) at five sites in northern England and Scotland, found that densities and breeding success of black grouse Tetrao tetrix was no higher on moors with a gamekeeper (and associated predator control) than on moors without a game keeper (average of 1.6 males/km2, 2.3 females/km2 and 1.8 chicks/female on 11 keepered moors vs. 1.9 males/km2, 2.7 females/km2 and 1.9 chicks/female on nine unkeepered moors, n = 9). Moors were an average of 50 km2.
