It is going to be a good fall!
Bowhuntia - I don't have the actual stats in front of me, but we have had this discussion here enough times in the past that I am pretty sure of my statement(s) below.
The 3 buck rule is NOT the reason for fewer top end bucks in Iowa. The number of hunters that actually shoot 3 bucks in a year, via the "extra" LO tag, is quite small. Something like 30 to 40 people per year.
However, the number of shed bucks shot during the late rifle season is many times that. Additionally, overall deer numbers are down significantly and along with overall numbers being down, there are lower buck numbers. The lack of super top end bucks is really not because of the 3rd buck tag, there are multiple other factors that far outweigh that one.
I think bowhuntia has a good point. A one buck limit forces a choice. If you had a one buck limit in Iowa, there would be more bucks and larger bucks (simple math). The guy that shoots that 140 inch buck with his bow on November 5th is then done hunting and cannot take another buck.
Another scenario would be that same hunter passing the 140 inch buck because he only has one tag, and then two years later that buck is 185".
Now keep in mind that I am not critical of Iowa on management, but that is the one area where my home state (Minnesota) has it right...one buck limit.
But then you throw party hunting into the mix, and all of sudden it is not a "true" one buck limit.
Long term I believe Iowa will have to address this, it certainly wouldn't hurt mature buck numbers by reducing the limit!
