Many ecologists have argued that predation is of little consequence in the regulation of gamebird numbers and that predator control in game management is a waste of time. Their case has included two lines of evidence; firstly, gamekeepers do not appear to be reducing predator numbers significantly; secondly, mortality by predation appears to be compensatory and therefore has little impact on gamebird populations as a whole. However, a closer examination of the activities of gamekeepers indicates that they do reduce predation pressure either by reducing or completely removing some predator species, or by temporarily reducing their number on a local basis. Recent research including an investigation of partridge population processes explored with a computer simulation model indicates that predation does regulate both autumn and spring densities. Other factors play an important role only when predators are removed.
