Mule Deer Doe in WinterRobby hosts Jeff Short, Wildlife Biologist for the Wyoming Game & Fish.  Jeff is a previous guest on the Rokcast. Last summer he shared his research on Antler Point Restrictions. On today’s episode, Jeff and Robby go over the recently released data on the survey of the Wyoming Range mule deer.

Wyoming recently released the official report on the 2022/2023 winterkill on the Wyoming Range. This report indicates nearly two-thirds of that herd was lost to that winter, dropping from 30,000 deer to 11,000 deer between surveys conducted in February 2023 and February 2024

They define Wyoming Range Boundaries and discuss why the survey was conducted two years in a row.  The survey showed fawn:doe ratios dropped to 34 while buck:doe ratios fell to 24.  Jeff talks about what it will take to recover this herd and the fact that deer on the winter range now have already started their recovery with good body fat levels and range conditions.

Robby Denning
Robby Denning started hunting mule deer in the late 1970’s, only missing one season in 35 years. At 25, he gave up the pursuit of all other big-game to focus on taking the best bucks possible. He began hunting the West on a DIY budget hunting an average of 30 days a year for mule deer. Robby loves the hunt as much as the kill and the entire process from research to scouting to hunting. He’s killed four bucks over 200 inches in the last 15 seasons, mostly on easily-obtained tags. He owns a public-land scouting service and runs a private-land outfitting business helping other hunters in their pursuit of deer and elk. Robby has scouted and hunted literally thousands of square miles of mule deer country and brings a wealth of knowledge about these experiences with him. To him, the weapon of choice is just a means-to-an-end and will hunt with bow, rifle, or muzzleloader – whatever it takes to create an opportunity to take a great mule deer. He is also the author of "Hunting Big Mule Deer" available on Amazon. Robby believes all of creation is from God for man to manage, respect, and through which to know its Creator
