Just some food for thought.
Deer numbers in Iowa are gigantic compared to here and I believe our numbers are healthy. I honestly don't believe mother nature ever deals out more than animals can handle.
I also believe that without plots they'd still have lots of food in Iowa and as a result, your herd would be healthy.
I don't know for sure obviously as I am an outsider looking in but things aren't too bad where there is little food in winter and there is snow on the ground for 6 months therefore things would seem pretty good in Iowa without all the food plots, no?
Just tossing out some thoughts, I'm one of those guys that sees an acre of standing beans in Jnauary no more "natural" than those beans combined and dumped. I know I'm in the minority but I'm looking at it with no dog in the fight so to speak.
Saskatchewan allows baiting. I tried it one yr and din't enjoy it and never killed anything there. We also have lots of cwd but almost 100% of the cases have been in prairie rangeland mule deer that don't come to bait so to speak yet 100's of whitetails group up in winter in areas of food such as grain piles left due to harvest or second cut alfalfa haystacks yet cwd is almost non existent. I'm no scientist but..............................weird.
There's places in IA where there's still very high deer populations- more timbered areas in very rural settings- far less food. The LOW populations are in the majority of the state- areas with small wood lots BUT huge areas of food. What would be ideal is to flip-flop those deer populations... Have high pops in areas with vast ag fields and have low numbers where it's mainly timber & pasture area with fewer ag areas.
There's many areas in IA where they have more timber with smaller fields.... those fields get combined in September through October. Right away you'll see 20, 30, 40 deer out there a night.... In my experience/opinion, lots of those fields are cleaned up within about 3 weeks usually. Especially with our advanced combining equipment. Now, in many cases, I've seen almost all the fields cleaned out by mid-Nov and starting in Dec- the deer are scratching around in them with little luck. Combine that with high deer numbers, a bad/cold/heavy snow winter with -30 temps, deer are put through major stress and we've heard of lots of cases where deer don't make it. If they do, the deer are very stressed, have sub-par racks next year, the does look thin/ribbed out, fawns are in rough shape, etc, etc. Bottom line: I do believe there's AREAS in IA where deer go through a great deal of winter stress and do not have adequate food for optimal conditions- everything from enough to die all the way to enough stress that they are not at optimal health. Leaving plenty of food for all critters gets many through winter, helps with recovery, helps fawns, moms & will in turn allow bucks to put more energy into growing racks next spring since they were able to build back up from the rut & winter.
Any extra food that can be left is well known to aid Pheasants through tough winters, turkeys, quail, deer, etc. Why many conservation/wildlife agencies will help with $, free seed, etc. At a MINIMUM, I know it helps on my place!
