Data
Where every number comes from
Every figure is the state's own published number, shown with its year. Nothing is modeled or filled in.
Montana
- Harvest and hunter counts, point-class breakdowns, 2021–2025: FWP harvest reports
- Antelope harvest and hunter counts, 2021–2025: FWP harvest estimates (MyFWP, species Antelope). FWP counts antelope hunters by district only in even years, and a hunter can hold up to three antelope licenses, so an antelope rate can top 100%. HD 413 and HD 485 are new hunting districts in the 2026 regulations, so no earlier harvest is shown for them.
- Deer rates divide each species' harvest by all deer hunters in the district — FWP doesn't count mule deer and whitetail hunters separately.
- License and permit rules, 2026: FWP deer, elk, and antelope regulations
- Antelope license rules, 2026: the same regulations' antelope licenses (printed p. 15) and Antelope HD Regulations (printed pp. 136–142)
- Hunting district boundaries: FWP ArcGIS REST service (live pull, simplified for the web); antelope districts from its Antelope Hunting Districts layer
Idaho
- Harvest and hunter counts: IDFG big game harvest statistics
- Season and tag rules, 2026: IDFG big game seasons & rules
- Game management unit boundaries: IDFG GIS data
Colorado
- Harvest and hunter estimates, 2019–2024: CPW elk, deer and pronghorn harvest reports. CPW's figures are estimates from its annual big game harvest survey. Deer counts mule deer and white-tailed deer together, and CPW's bull and buck counts aren't split by antler points.
- License rules, 2026: CPW big game brochure
- Game management unit boundaries: CPW ArcGIS (CPW GMU Boundary, Big Game)
Wyoming
- Harvest and hunter figures, 2021–2025: WGFD elk, deer and antelope harvest reports. WGFD's reports give harvest and hunter success as estimates from a survey of license holders; the 2024 and 2025 reports describe it as a voluntary harvest survey, extrapolated to the licenses issued. WGFD reports spikes in their own column, apart from bulls, and its 2025 elk report defines a bull as “any branch-antlered adult male, which excludes spikes.” Mule deer and white-tailed deer are reported separately, each with its own active hunters. Antelope hunters can hold more than one license, so an antelope rate can top 100%.
- License rules, 2026: WGFD hunting season regulations, Chapter 5 (Antelope Hunting Seasons), Chapter 6 (Deer Hunting Seasons) and Chapter 7 (Elk Hunting Seasons).
- Hunt area boundaries: WGFD ArcGIS (ElkHuntAreas, 2026_Deer_Hunt_Areas and AntelopeHuntAreas)

How a success rate is computed
Success rate = animals harvested ÷ hunters afield, for the year and unit shown. The All column uses every animal of the species. Bull and Buck use antlered animals only — for elk, branch-antlered bulls, with spikes counted separately. 6+ pt and 4+ pt use the top point-class tier. The denominator is always total hunters afield. Montana and Idaho don't publish hunter counts by the animal hunters were after, and CPW publishes antlered and antlerless hunter counts only for some seasons and leaves out either-sex licenses. In Colorado, elk Bulls and deer Bucks are CPW's bull and buck counts, which CPW doesn't split by antler points, so spikes aren't counted separately. Colorado Bucks for pronghorn are CPW's buck counts. In Wyoming, Bulls are WGFD's bull counts, which leave out spikes; spikes have their own rate. Wyoming Bucks for antelope are WGFD's buck counts. In Montana, Bucks for antelope are FWP's buck counts.
What “not published” means
Montana surveys deer hunters in odd years and elk hunters in even years, and FWP counts antelope hunters by district in even years (its statewide antelope rows have hunters every year), so half of all district-years have no hunter count by design. Idaho does not publish point-class data for every unit. When a figure does not exist, the cell says so; the site never fills a gap with a number the state didn't publish.
Refresh schedule
Harvest data is updated when each state publishes its annual report, typically spring. Regulations are updated for each new season.
