Park ranger
The duties of the modern park ranger are as varied and diverse as the parks where they serve and in recent years have become more highly specialized. Regardless of the regular duties of any one discipline, the goal of all rangers remains to protect the park resources for future generations and to protect park visitors. This goal is accomplished by the professionalism and sometimes overlapping of the different divisions. For example, an interpretive ranger may perform a law enforcement role by explaining special park regulations to visitors and encouraging them to be proper stewards of natural and cultural history. Law enforcement rangers and other park employees may contribute to the mission of the interpretive ranger by providing information to park visitors about park resources and facilities. The spirit of teamwork in accomplishing the mission of protecting the parks and people is underscored by the fact that in many cases, for the U.S. National Park Rangers in particular, all park rangers share a common uniform regardless of work assignment.The Adopt A Ranger Foundation has calculated that worldwide about 150,000 rangers are needed for the protected areas in developing and transitions countries. There is no data on how many rangers are employed at the moment, but probably less than half the protected areas in developing and transition countries have any rangers at all and those that have them are at least 50% short. This means that there would be a worldwide ranger deficit of 105,000 rangers in the developing and transition countries.
California State Parks Peace Officer
California State Park Peace Officers (S.P.P.O.) are fully sworn California State Police Officers, with two sub-classifications, the Ranger and the Lifeguard. S.P.P.O.s often use the title of State Police Officer during enforcement contact, as many Park Rangers and Lifeguards within municipalities, counties and special districts are not armed Peace Officers, with authority throughout the state, on and off duty, like the California State Park Peace Officers law enforcement officer. State Park Peace Officers perform a wide variety of general law-enforcement activities, including complex criminal investigations, traffic enforcement, and participate in statewide task forces, for gang suspension, narcotics enforcement, auto theft, and fish and wildlife crimes, under the jurisdiction of the California Department of Parks and Recreation in the state parks of California, United States. Duties include general law enforcement, aquatic rescue (by lifeguards and other certified officers), search and rescue, emergency medical response, interpretation of natural, historic and cultural resources, resource protection, park management and proactive enforcement patrol. The current sidearm of the California State Park Peace Officer is the Smith & Wesson M&P, the current patrol rifle is the Colt AR-15 Model LE6920, and the current patrol shotgun is the venerable Remington Model 870 Police Magnum.Both Lifeguards and Rangers work in conjunction to enforce state law and park regulations in the 280 parks under the jurisdiction of the State of California.
