Park ranger
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.

DCNR Rangers act much like a national park ranger does. They routinely check on cabins and campsites, offer insightful answers to visitors questions, and help to maintain calmness throughout the parks. They have full arrest powers while in park lands and carry sidearms. However, they do not have jurisdiction over Pennsylvania State Game Lands, which are patrolled by Wildlife Conservation Officers employed by the Pennsylvania Game Commission. DCNR rangers enforce game laws as well as fishing and boating laws in state parks. However, the Pennsylvania Fish and Boat Commission is completely independent of the Pennsylvania Game Commission. Both agencies are independent of DCNR, but work in cooperation with each other.
