I was in the eastern side of the Bridger area from Nov 15th-26th. I didn't see a single antelope while driving through the BLM land. I had seen 2 dozen plus in the same area the previous October 15th-25th. I'm not sure which one was normal, so take my tiny sample size for what its worth.
They could always recover, but it would take several years of favorable weather to do so. This winter is looking good for them, now we just need 3-4 more. I really wish they would just get rid of doe tags
Hopefully more antelope friendly fencing on migration routes will help reduce the winter kill in addition to more favorable winter conditions. The antelope dealt with severe winters in the past before the west was crisscrossed with cattle fences. I don't know what effect the fencing has but I suspect it has resulted in bigger population swings when winter conditions are unfavorable.
In South central the numbers were slightly improved from rock bottom but the age class was all 2 years or less.
I drove most of the state in fall 2023 and it was really, really bad.
The pronghorn populations peaked between 1980-2006 at around 600k. Winters hit them hard and oil and gas development has not helped in the last 15 years.
