Environmental Police Officers serving in the inland regions are responsible for enforcing a wide variety of laws and regulations including the statutes regarding hunting, fishing, trapping, boating, and off-highway vehicles. Inland officers also investigate cases of illegal waste disposal, wetlands violations, and assist in search and rescue efforts. Officers patrol in cruisers, four-wheel-drive vehicles, boats, off-road vehicles, on foot, and in aircraft when necessary. Inland officers pay particular attention to state forests, parks, wildlife management areas, boat access sites and heavily-used public waterways such as major rivers and great ponds.
