A deer farm is a fenced piece of land suitable for grazing that is populated with deer such as elk, moose, and even reindeer raised for the purpose of hunting tourism or as livestock. (This practice differs considerably from the way that Arctic communities like the Laplanders migrate in open country with their herds of reindeer.) The technique has expanded in recent years due to the rising popularity of venison. New Zealand is the largest supplier of farm-raised venison. As of 2006 New Zealand had approximately 3,500 deer farms, with an estimated stock of 1.7 million deer.
