Or close to it.
On my hunt in 2016, due to the prior flooding of the past couple years or so, there was a tremendous acreage of new brushy areas (no trees large enough to climb, no visibility from ground). This was something different compared to prior years when these areas HAD been soybean fields and/or just fallow.
IMO, the appearance of these large acreage brushy areas has contributed to the decline in hunter success, as before this happened, during the first few years, the deer had relatively much less "security" cover.
So here's what I experienced in 2016 ---- the scouting day suddenly has people walking around "scouting" everywhere a man can walk. ATV's are zooming everywhere an ATV can be ridden. So on the scouting day, the deer sought refuge from this "invasion" simply by going into those big brushy areas, and pretty much just staying there until after the hunters left 3 days later.
I personally see no way the PI WMA can ever again approach the hunter success rates it experienced during the 1st few years, in large part because of all the additional security cover, as well as the deer density being dramatically reduced (which was in fact the goal).
Also heard a few rifle shots on the island during my hunt, so assume all the public land hunters really helped push more deer onto the private lands on the island (where they were hunting with rifles under Unit L regs). Have heard they kill some high-scoring mainframe 8-pointers which are not legal for harvest on the PI WMA. Who doesn't consider a mature 140-plus-class mainframe 8 a real trophy buck anywhere in TN?
