US Forest Service - Roosevelt National Forest (CO)

The Roosevelt National Forest comprises 813,799 acres of mixed-conifer forest spread across the foothills and mountains of Larimer, Boulder, and Gilpin counties in north-central Colorado. Management of the forest is split into two ranger districts, the Boulder Ranger District, headquartered in Boulder and overseeing operations in Boulder and Gilpin Counties, and the Canyon Lakes Ranger District, headquartered in Fort Collins and in charge of operations in Larimer County. The forest is a sub-unit of the jointly administered Arapaho, Roosevelt, and Pawnee National Forests and Grasslands. Together the three management units comprise over 1.5 million acres of public land in the north-central Colorado Front Range.

Radio Frequencies

The forest relies upon the combined Arapaho, Roosevelt, Pawnee (ARP) radio network for communications. This radio network is a product of the combined administration of the Arapaho National Forest (in Clear Creek and Grand counties), the Roosevelt National Forest (in Larimer, Boulder, and Gilpin Counties), and the Pawnee National Grasslands (in eastern Weld County). Previously, the radio networks for these forests were divided into two separate systems: the Roosevelt Net (which also served Pawnee) and the Arapaho Net. The 2016 NTIA federal re-banding mandate resulted in additional improvements to these networks, causing them to be consolidated into a single network divided into three geographical areas: North, for Roosevelt and Pawnee operations, South, for Arapaho operations on the Clear Creek Ranger District, and West, for Arapaho operations on the Sulphur Ranger District. Dispatching and resource tracking on the Arapaho, Roosevelt, and Pawnee National Forests and Grasslands are handled through the Fort Collins Interagency Dispatch Center.

North Repeater Net (Roosevelt National Forest & Pawnee National Grasslands)

• The North Net of the Arapaho, Roosevelt, Pawnee (ARP) radio system serves the Roosevelt National Forest and the Pawnee National Grassland in Larimer, Boulder, Gilpin, and Weld Counties.
• "Tone #" refers to the National Standard Tone Numbering System used by the USFS, BLM, and other land management agencies and is only applicable to TX tones.
• The North Net does not use any tones on output.
• Daily Fire Management Briefings are broadcast by Fort Collins Dispatch at approximately 1000 and Fire Weather Forecast Discussions are broadcast at approximately 1600 from the Buckhorn Base/Repeater site.

Intra-Crew, Work, & Tactical Frequencies

• General use work channels/frequencies are generally restricted to low power use in handhelds for the purpose of intra-crew communications. These frequencies are part of a shared NITA Itinerant/Common Use pool (see: Federal Government Itinerant) and not reserved for use by any one specific user/agency.
• On extended attack incidents, frequencies from the National Incident Radio Support Cache pool are likely to be assigned.
• Local/initial attack incidents may be assigned frequencies from the VHF portion of the NIFOG Interoperability pool (see: Common Public Safety#VHF High Band) to allow for direct coordination with local resources.
