Gamekeepers are responsible for keeping our natural environment, often upset by growing human urbanization and infrastructure, in a carefully controlled balance. For example, in recent years, the wild boar numbers have been soaring across Europe causing a decline in the numbers of other wild species as well as causing severe damage to the forests themselves. Since wild boars have no natural predator, they can roam free and breed uncontrollably upsetting local ecosystems. For these reasons, in the 2011 season alone, some 141,000 wild boars were killed – many in the attempt to keep the population spiraling out of control. In comparison, in the winter of 1970/1971, a mere 4803 wild boars were killed. Aside from animal population control, gamekeepers have historically had the responsibility to protect the natural habitat they oversee by caring for the trees and plants as well. This often goes hand in hand with animal control and targeted feeding in winter months.
