Archery seasons equate to more man hours spent per animal harvested. Simply put, there is a much less chance of success with a bow than with a gun, and a typical bowhunter puts in more time in the hunt than a typical gun hunter. The Departments all have figures from years and years.
The results of three months of bow season, at least in WI, does not even come close to the kill figures of ten days of gun season, or, in fact, to the numbers posted from the first two days...opening weekend. Once again, more hours of enjoyment in the field for every animal harvested, with not a great impact upon the herd.
The various Departments are there to protect and monitor the resource while providing opportunity for the most hours of outdoor participation possible. At least...that is my point of view.
