Depends on how complicated you want to get. We eyeball it where I hunt in King County and our B/D ratios are about 2:1; however our 8 pt or less to 8 pt + ratios are about 6:1 so we are shooting every 3.5 yr old or older 8 point or less buck we come across and then taking a doe for every buck. We supplemental feed, but it's expensive and I'm not sold yet as to the effectiveness in an uncontrolled habitat which in our case is defined by no high fence, big limited or non hunting neighbors, etc... What I am seeing is many of our early season target trophy caliber bucks are leaving the property once they've shed velvet and don't return, if at all, until after the season. So basically we're feeding some good deer that don't hang around for hunting season. Now that's all part of the program when feeding free range deer and if you can afford it, no big deal, you know what your in for; but if you're on a budget, I wouldn't supplemental feed. You can manage pretty effectively by limiting your herd and allowing your genetically superior bucks to reach old(er) age. Sadly, our biggest problem seems to be not killing enough deer. Generations of non management is a challenge to overcome. MLD will help with this problem if you have the time and an owner that will implement it.
How come everybody I meet is a deer hunting expert?
