Sounds like some big resident land owners, probably farmers, have the ear of the top state officials. No party hunting and 3-5 years to draw a tag? You have effectively eliminated deer hunting for non resident landowners.
Sounds like the resident big land owners are tired of non rez's shooting "their" deer. This could lead to some real unintended consequences. This may be also to drive land prices down on non-rez properties.
I don't know what it is like in Iowa, but deer hunting brings in a ton of revenue to small communities in Wisconsin. During gun hunting, the bars/restaurants are full. Gas stations, grocery stores, liquor stores, hardware stores, and sport shops are all busy. If the state would lose and estimated $700k in license fees, they will lose many times that in tourism $$ and taxes.
Pretty sure that non-resident land owners would have standing and could show they are harmed parties. Raising non rez fees is one thing, but nearly eliminating hunting privilege's is a huge issue. Likely a lawsuit is going to be filed.
