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.
Junior Ranger Program
The "Junior Ranger Programs" are activities prepared especially for 5- to 12-year-old visitors to the properties of the National Park Service. Children and their families participate in the program by completing prepared activity books which are generally free, but in a few cases can cost up to $3. The activity books direct children to areas they might otherwise miss, or to things of special interest to the age group. The booklets contain information that helps children and their families discover the importance of a park on their own terms, and decide what the park means to them personally. After completing the specified amount of pages for the child's age group, the participant is awarded a patch, badge and/or certificate, unique to each park. The Yellowstone National Park was the first to start the Junior Ranger program.
