Pannage

Pannage is the practice of releasing livestock-pigs in a forest, so that they can feed on fallen acorns, beechmast, chestnuts or other nuts. Historically, it was a right or privilege granted to local people on common land or in royal forests across much of Europe. The practice was historically referred to as Eichelmast or Eckerich in German-speaking Europe, and Montado in Portugal. The fee to feed one's livestock in such a way was historically referred to as žirovina in Croatia and Slovenia.
