Forest Rangers

A park ranger, park warden, or forest ranger is a person entrusted with protecting and preserving parklands – national, state, provincial, or local parks. "Parks" may be broadly defined by some systems in this context, and include protected culturally or historically important built environments, and is not limited to the natural environment. Different countries use different names for the position. Warden is the favored term in Canada, Ireland, and the United Kingdom. Within the United States, the National Park Service refers to the position as a park ranger. The U.S. Forest Service refers to the position as a forest ranger. Other countries use the term park warden or game warden to describe this occupation. The profession includes a number of disciplines and specializations, and park rangers are often required to be proficient in more than one.

In medieval England, rangers were officials employed to "range" through the countryside providing law and order (often against poaching). Their duties were originally confined to seeing that the Forest Law was enforced in the outlands, or purlieus, of the royal forests. Their duties corresponded in some respects with that of a mounted Forester.

The term ranger seems to correspond to the Medieval Latin word regardatores which appeared in 1217 in the Charter of the Forest. Regardatores was later rendered as rangers in the English translations of the Charter. However, others translate regardatores as regarders. For example, the fifth clause of the Charter of the Forest is commonly translated thus: "Our regarders shall go through the forests making the regard as it used to be made at the time of the first coronation of the aforesaid King Henry [II] our grandfather, and not otherwise." A "regard" is considered to be an inspection of the forest.
