Gary Olson
conrad, MT
Gary’s FWP career was based out of Conrad as an area biologist from 1977-2011. Gary surveyed HD 441 bighorn sheep area for over 30 years and helped with several tagging, transplanting and monitoring efforts from Wildhorse Island, the Sun River, the Blackleaf WMA and in the Anaconda area.

HD 421, 422, 423, 424, 441
Total counts look good in all areas. Lamb ratios above average at 48:100 ewes, overall ram numbers look good as well. 100% hunter success in 2025 with 9 tags available, average age at 7.8 years. 37 more collars will be deployed on rams and ewes this winter. Winter surveys are on-going in December and January.
HD455 — Big Belts
Just under 100 sheep were observed during the last aerial survey. Lamb recruitment is down from past years surveys but overall numbers appear to be stable. Hunters were 100% successful with 2 permits issued. Rams averaged 7-8 years old.
HD482 — South side Missouri Breaks
A July 2025 survey revealed 317 sheep, 82 rams, 151 ewes, and 75 lambs. Lamb numbers were very good at 50:100 ewes, rams were 54:100 ewes. Hunter harvest was 8 rams with 5 permits offered. The governor’s tag and super tag hunters always hunt HD482, which accounts for additional harvest beyond the regular permit offering. No sign of sick sheep so far.
HD416 — Little Belts
Fall surveys accounted for 21 bighorns, but some collared ewes were not located so this is considered a minimum count. No evidence of continuing disease in this group from 2023-2025. Lamb recruitment appears to be trending upward in 2025, as several lambs have survived into the late fall period. FWP will put additional effort towards tracking yearling survival in 2026.
