Paul,
Whats your defintion of mature, I bet it isnt the same as mine. I dont consider any brow tined bull a mature bull.
Also, please educate yourself and talk with a few biologists and get out of the 'root.
Oh, and I'd bet that your herd of 30 rags would be there regardless of a brow-tine only season...I wonder if your 30 rags are even IN that hunting area during the season? I'd guess not.
The MTFWP, U of M, etc. have done exhaustive studies on brow-tined restrictions...without getting techinical they provide exactly what I described, you shift your kill from a 1.5 year old spike bull to 2.5 year old raghorns....and thats a fact. Studies have also shown very little, if any, recruitment of trophy class bulls (6+ years old) into the population.
Colorado basically has the same management...care to guess what the average age bull killed there is? Care to guess how the recruitment is for even 5 year old bulls?
Hey, I'll be the first to admit, its a great management plan if your objective is to kill rags instead of spikes...works great.
