Dispatch Area
The COIDC dispatch area spans roughly 8.8 million acres of Central Oregon — high desert, forested mountains, river canyons, and protected lands.
Coverage
The dispatch area covers approximately 8.8 million acres (2025 GIS boundary), reaching from the Cascade crest in the west, across the high desert, and into the John Day drainage and Blue Mountain foothills in the east. Within it, COFMS and the Oregon Department of Forestry are cumulatively responsible for wildland fire management on approximately 4.5 million acres of public and private land. The area averages more than 300 fires per year.
Fire Danger Rating Areas
The dispatch area is divided into six Fire Danger Rating Areas (FDRAs), each with its own fuels, stations, climatology, and fire-danger thresholds:
| FDRA | Code | Description |
|---|---|---|
| East Slope | 01-ES | East slope of the Cascade Mountains, from the crest to the WUI. |
| Monument | 02-MN | Newberry Volcanic Monument, Green Ridge, and the WUI of Bend, Sisters, and La Pine. |
| Columbia Plateau | 03-CP | Lower Deschutes and John Day river canyons. |
| High Desert | 04-HD | Higher-elevation lava plains of the central high desert. |
| Ochoco-Maury | 05-OM | Forested western extent of the Blue Mountains. |
| John Day Basin | 06-JD | John Day River drainage and the central Blue Mountain foothills. |
Because fuels and climatology differ across these areas, fire-danger thresholds are set per FDRA. See Fire Danger for current conditions in each area.
Partner jurisdictions
Land within the dispatch area is protected by a mix of agencies — the BLM Prineville District, the Deschutes and Ochoco National Forests, the Oregon Department of Forestry, and the National Park Service at John Day Fossil Beds. See Partners for each agency's area and mission.
