Very loosely off the cuff…. Farms in iowa with say half timber & half ag (which is not majority of state!!!) …. the land can hold for ONLY health of herd…. Per square mile
Very low: 5-25
Medium: 26-50
High: 50-75
“Too high”: 100+
Few points….
1) is a dude leaving tons of standing food & tons of natural browse created? If so, even over 100 deer PSM would be fine. Very few are or would do that though
2) the huge reality of farming…. No farmers are gonna be ok with #’s when they get insane of course. & if u are 100% farming & leaving 0 plots- can’t have #’s that high anyways.
3) reality is, most 50/50 farms are probably around the 10-35 deer side of it. Some pockets higher of course. So- what we “want” if we wanted “lots of deer” is for sure NOT what’s out there right now. A few counties or a few pockets across state are exceptions of course.
4) most of state is wide open with very few deer. Carrying capacity is maybe 1% of what it “could be” but clearly that’s in ag regions where there’s only one goal: top yield on corn & beans.
5) social stress is a factor. IMHO - it’s less so than I would have said even 5 years ago. Maybe because I dont really see it much now with lower populations though.
6) all timber areas…. Way less of course. All ag- way more but no cover to hold them so both have issues.
Back on point …. In my fairytale world of “deer paradise” where deer were priority #1 & crops didn’t mean a thing…. 50% timber farm…. Leaving tons of food & having every drop of the timber full of browse, mast productions & cover…. Ample food 365 days a year through diversity. I’d pry shoot for 100 deer per square mile. Reality where we want to balance farming, deer damage, disease, reality of how much work we want to do to land…. Maybe 50 deer per square mile. This is all my wild guess ramblings that if u asked me a week from now- I’d give u different figures
