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.
Parking enforcement officer
Civil enforcement officers (England, Wales, Scotland), including those previously known as parking attendants (whose duties might still be limited to parking contraventions or might now be extended to other road traffic contraventions where a local authority has chosen to do so), are employed by local authorities or a contractor providing their services to a local authority. Since the advent of decriminalised parking enforcement, they have largely replaced traffic wardens as the primary enforcers of parking regulations. They have the power to issue penalty charge notices (PCNs) for parking contraventions dealt with by ss.63-79 Road Traffic Act 1991; in areas where their duties have been extended beyond that of a parking attendant they can also issue PCNs for parking offences coming under other legislation such as e.g. parking a vehicle entirely on a footway or the parking of a detached vehicle trailer or skip.
