The Effect of an Experimental Reduction in Predation Pressure on the Breeding Success and Population Density of Grey Partridges Perdix perdix

1. A 6-year experiment is described which was designed to test whether or not predation control, as practised by traditional and currently legal methods, increases (i) the breeding success and autumn numbers of partridges, and (ii) the subsequent breeding density. 2. In the experiment, predation control effort was highly seasonal and designed to reduce partridge breeding season losses by killing resident predators of selected species. 3. The...
