Happening all over Alabama on a much more regular basis than most people realize. In Alabama, if you're actively managing for mature bucks (4 yrs and older), a good rule of thumb is that you should be able to harvest 3-5 bucks per year off 1000 acres depending on the quality of your property and what your neighbors are doing. Basically 1 buck per 200-300 acres, once again depending on land quality and location. Bad neighbors, that 3-5 drops to 0-1 or 0-2. Great neighbors, large landowners all around, all on the same program, real good quality land, letting all bucks younger than 4 walk, you might be able to harvest 6-8/yr or even more, without hurting it, in an established program. So yes, a single 20 acre landowner with 3 sons, all of which can kill 3 bucks each (12 in total per year legally) and unlimited does can absolutely ruin any attempt at managing a 1000 acre property. Or, if it was already being well managed, the 20 acre landowner that moves in and starts shooting any buck they see, can ruin years of management efforts in just a few seasons. 12 bucks a year off the 20 acres will be well in excess of what the guy managing the 1000 acres will harvest/yr and none of the bucks killed on the 20 will grow up, live/stay on, or even spend 10% of their time on that 20 acres. But when they walk across that 20 acre piece, and they will walk across it many times a year and during the season, they'll get whacked. And Matt's right. Small property management, 1000 acres or less, has zero chance of success without the surrounding neighbors being on the same page and working together, or in a best case scenario for the deer manager, not hunting their properties at all.
