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.

The Urban Park Rangers was founded as a pilot program in 1979 by then Parks Commissioner Gordon J. Davis, with the support and encouragement of Mayor Ed Koch. The program provides many free programs year-round, such as nature walks and activities. They also operate programs such as "The Natural Classroom" for class trips and the general public alike. "Explorer" programs are available for activities such as canoeing in the city's flagship parks in all five boroughs. NYC Urban Park Rangers are easily identified by their uniforms.
