NATURAL RESOURCES POLICE is the state agency responsible for enforcement of boating, hunting, fishing, and natural resources laws. Each Natural Resources Police Officer is granted police powers as conferred upon any other law officer of the state and may excercise these powers statewide (and in some portions of Virginia). DNR Police use the APCO 10-codes.


FOREST & PARK SERVICE (Forest Rangers, Park Rangers, and Wildlife Rangers): are responsible for the enforcement of the laws, rules, and regulations enacted for the protection of the State forestry reservations, State parks, historic monuments, recreation areas, or for the protection of fish and game. Forest Rangers, Park Rangers, and Wildlife Rangers are all granted the same powers and authorities as Natural Resources Police Officers, but may only excercise these powers on lands under the control of the State or Federal government.


The Forest and Park Service operate a series of repeaters all across the state as well as the Natural Resources Police. In order to organize these repeaters and keep units from stepping on each other, different input tones were assigned to access certan repeaters. The following tables of tones were uncovered through dilligent listening. Often you can hear the field units call the dispatcher and identify which repeater they are using. A forest and park service example would be as follows: "41-41 to Tawes on Tone 300". This would indicate to the PCO at Tawes that the unit was calling them on the Madonna repeater with a input tone of 88.5. A NRP example would be as follows: "396 to Tawes on Gwynbrook High-Band". This would indicate to the PCO that the unit was calling them using the Gwynbrook repeater and a input tone of 114.8. All the DNR radios are programmed with scan. Portables have 10 banks of 16 channels. Because all of the radios have a scan function it is possible for Tawes to put out a call on a simplex frequency like 151.415 (N. Parks) and get a response on a completely seperate frequency. Natural Resources Police units are equipped with both Lo-band and High-band radios, when they are used the units will identify which band they are calling on. Also note that the Recieve frequencies and tones are the same statewide, it is only the input tones that differ.
