Recently the Wyoming Game and Fish Department released an update on their annual observational flights of the famed Wyoming Range and Sublette mule deer herds. These wintering deer largely make up what nonresidents know as Regions G and H – Wyoming’s classic high-country deer hunting areas.
The Wyoming Range, in particular, felt the brunt of the losses from the winterkill two years ago with an estimated 80% of the deer lost from December until winter loosened its grip. The estimated number of deer went from 30,000 in December of 2023 to 11,000 the following December (which included a new fawn crop). Luckily, the incredible snowfall and continued precipitation turned into some of the best groceries for those deer to rebound on, and this year’s flights showed it.
Game and Fish agencies across the West do surveys like the ones in western Wyoming to keep track of how many fawns are growing into the population, as well as maintain a specific buck ratio. In this part of Wyoming, however, surveys and studies have been even more intensive as these iconic deer herds steadily declined from a big peak of around 60,000 animals in the early 1990s. Especially after the hard winter of two years ago, WGFD has kept flying to get a more accurate read on how the deer herd is trending.
While the Wyoming Range herd is far from the numbers of individual deer from the 1990s, biologists say the fawn recruitment was as good as they had seen since the heyday of deer some 35 years ago. The 83 fawns per 100 does they saw from the air was only rivaled by one year since the historic peak in 2000. That means that on the backside of one of the most devastating winters, the habitat in the Wyoming Range provided the best fawn production since those winter ranges got cell service.
