Illinois Department of Natural Resources-IDNR WEB
Park rangers in Illinois work for the Illinois Department of Natural Resources (IDNR) or the Illinois Historic Preservation Agency. They are responsible for the care, maintenance, and improvement of the sites they work at. They also supervise the site technicians who carry out the maintenance and outdoor recreational and interpretive programs.
IDNR Conservation Police
- In July of 1995, the Department of Conservation merged with several smaller departments to form what is now the Illinois Department of Natural Resources (or the DNR), yet we are still referred to as Conservation Police Officers. Since the beginning, the first title of "Game Warden" seemed to be the one that has endured, and many people still use that title today for CPOs (not only in Illinois, but throughout the country).
Today, although CPOs have full police authority in the enforcement of all Illinois Compiled Statutes, their enforcement mission is to focus upon those laws and activities associated with natural resource protection and recreational safety. Examples of the duties include: Enforcing criminal laws, vehicle laws, drug laws, etc. in the State Parks. Patrolling on Illinois lakes and rivers to check boating safety equipment and watercraft registration Enforcing the fish and wildlife laws (checking hunters, trappers, sport and commercial fishermen for licenses, fish & game size/possession limits, season dates and hours, etc.) Enforcing timber buyers and forest products transportation laws; endangered species laws; snowmobile registration and operation laws; Federal fish & wildlife laws; commercial establishments (e.g fur buyers, taxidermists, fish markets) and Departmental (DNR) Administrative Rules & Regulations. Not all of the duties involve enforcement. A CPO's workload involves non-enforcement activities, such as: Speaking at sport or hunt clubs, civic organizations, school classes, etc. Staffing information booths at major sports, travel or boating expositions, or during "Law Enforcement Career Days" at specific colleges/universities/high schools in Illinois Assisting with hunting, boating, and snowmobiling safety education programs Assisting other law enforcement agencies, or to help in certain emergency/rescue situations Providing instruction to other police agencies in certain "Conservation type" laws or related enforcement procedures Working with college students who earn credit hours in an internship program, by working with veteran Conservation Police Officers to learn about the duties and responsibilities. Attending various in-service type training programs such as: legal and legislative updates, first aid/CPR refreshers, and officer survival training (self-defense and use of firearms); and specialized schools (such as forensics, commercial establishments, sonar use, waterfowl enforcement, interview & interrogation schools, DUI and OUI enforcement [operating watercraft while under the influence alcohol or drugs], accident investigation [boating/hunting], etc.).
