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.
Law enforcement in Australia
Council rangers are officers employed by local government areas in Australia to enforce the by-laws (local laws in Western Australia); of those local governments and a limited range of state laws relating to such matters as litter control, animal control, dog laws, fire control, off-road vehicles, emergency management, and parking. Unless they are also sworn in as special constables, as many are, rangers do not have full police powers. Council rangers are also referred to as local laws officers in some of Australia's eastern states. Most Council rangers have the power to issue fines that don't exceed a certain amount.
