Does/Bucks ratio

8 posts in this topic

What's considered a healthy or sustainable ratio of does to bucks? I always wonder how many does each buck is assumed to breed, or capable of breeding. Where I'm going with this: the premise is that harvesting only bucks helps bring back the deer population, because you don't need a bunch of bucks for good reproduction, but you do need a bunch of does. But how many bucks, relative to does, is enough?

I thought it was 2:1, but that was ideal for the hunter not for regenerating a decimated herd.   Keep in mind that's reproducing does not fawns.  

The fact of the matter is, and I think this is part of the question is that does don't necessarily pick out old Mossy Horn to reproduce with.  Old Mossy horn may be better at fighting and finding does but a doe will "do the deal" with just about any buck when she's ready .  She doesn't look and say "wow, look at his antlers and how big and strong he is" or "look at his basket rack and how skinny he is, I'm out of here."

When Old Mossy Horn is locked down with a doe the other lowly bucks are still mating with the other does.  They aren't all waiting for him to come out of the bedroom for doe #2 with his smoking jacket on.

Good question as it pertains to getting deer numbers back up.  I'd guess it's the total deer that the land can feed.

That is a good question. Hard to get a definite answer.  I'm sure biologists and groups like qdma have some answers to this.  

A couple things that come to my mind are a bucks genetic makeup is the same regardless of their age.

Another, is does that don't get bred do have another estrus cycle a month later.

Seems like I read somewhere that it's rare for a buck to breed more than 4-5 does a season.  That said, they should be able to handle a 3-1 ratio relatively easily.  I also read recently that some biologists suspect most doe fawns that get bred are bred by buck fawns, which kind of makes sense to me.

From what I've read, even in the most unbalanced deer herds it is hard to get a doe to buck ratio much higher than 2:1.  That is because they are born at a 50:50 ratio.  Every year there are a bunch of bucks born.  The only time you really see bad doe to buck ratios is when you have really abnormally high fawn mortality.  I've also read that even in the most unbalanced situations, almost every doe still gets bred.

 The deer holocaust brought our buck/doe ratio to about as good as you can get in a wild herd, but now with  conservative doe harvest and 480,000 buck tags for 300,000 bucks in the deer population, the buck doe ratio will take a hit along with any sort of age class of bucks except for zone 3 where they actually have deer management.

Agree smellesox exactly what's happened the past couple years in my area fawns are not surviving at all. Bears, Bobcats, Wolves, Coyotes, and stray dogs have all been seen off and on in or adjacent to the section I live in, it's a bad time for it to be predator central after a mild winter but it is. Had 7 bucks and 2 does and 1 fawn on camera here since July 1st, maybe the predators pushed them out but talking to many guys they don't have much for deer either. Spot #2 many counties away on a salt block since July 1st had about 8-10 antlerless deer on camera and 15 bucks of varying sizes. Spot #3 15 miles from there had 9 bucks and 2 does and 1 fawn on that camera. Camera's aren't the tell all but talking to local people etc. in all three of these counties close to where I hunt they're all reporting the same thing, not a whole lot of antlerless deer around, seem quite spread out and about. Lack of fawns and they should've had twins for sure this spring. The buck to doe ratio I think where I'm hunting there's no doubt there's at least as many bucks around as does, hopefully that'll work itself out but there isn't much a guy can do predator wise other then the coyotes and I think as thick as they are running hard every night they are the main culprit for sure.

    •   No expert here either but I've talked to a couple.    Would your new, expanded slab be conducive to making the addition another zone or zones?  You could maybe run that expansion off different lines from the manifold above the slab so you don't have to route and pour over seams.   Definitely insulate below with GOOD insulation.  As mentioned, heat doesn't really rise the way we think it does; it moves to the cold and the earth will soak it up.   Heating your loop would be cheapest with a natural gas fired boiler, propane second.  Geothermal is expensive to put in so your payback on a new system is long.  Air source heat pumps are great until it gets really cold.  In the end, radiant in floor is the most efficient way to heat, but yes, it's slow to respond.  But if your toes are warm, you will be too.
    • I appreciate the response, I take nothing personally and didn't mean to be snippy in my reply. There are a lot of great comments on here and I will keep you posted on what I decide. Thanks again. 
    • Ice is quickly thinning on those northern lakes that still have ice with dangerous conditions on most lakes. The Wisconsin River is now open even in its northern stretches, but ice chucks can be seen melting along the river's edge. The lower Wisconsin River has finally dropped to near normal levels. Some walleye and brown trout are being caught on the Menominee River both trolling and angling from shore. Low water and cool water temperatures slowed the walleye run so far on the Oconto River. Anglers along the Wolf River have been starting to catch walleyes. A few sturgeon have been seen along the Wolf River, but warmer temperatures are needed for the sturgeon to start their annual spring spawning run. Walleye and sauger action on the Wisconsin River and Lake Wisconsin is slowly picking up.The steelhead season opened on the lower stretch of the Brule River last weekend and anglers reported good successPhoto Credit: DNRSpring steelhead fishing opened last Saturday for the lower stretch of the Brule River and there were lots of fishermen and fisherwomen on the river many who had a successful opener. .
    • I apologize if that came out wrong. The idea might very well be the best route to go. It's just that over the past 25 years or so I have seen many attempts to save a dollar that cost a buck and a half to do lol.    Here are my two cents. If you have a slab and you want to pour on top of it while keeping the same footprint that sounds pretty doable and could probably save some money if you don't have to change drain lines, run water, heat runs, electrical etc into the slab.   If you intend to tie into the existing slab and run zones of pex across the joint and have the new and old floors end up at the same elevation it still can be done. Some contractors will not want to mess with tying into and raising the elevation of the slabs and will prefer to start from scratch especially if you as the homeowner want them to warranty the finished product.  The critical thing would be to use enough rebar drilled into the old slab and have enough compaction and sufficient footings to make sure the slabs stay where they are without settling. That would make all kinds of problems with the pex.    Hopefully that response came across better.
    • It'll be interesting to see if the team plays a little harder in front of a different goalie. 
    • Hawg, I'm with you on this one !
    • Check and see if you have a video output on you device. You may be able to record to a digital device.
    • Just use plain old spray paint in a can. I've done it many many times and seems to stick really nice. Nothing special either I can't even tell you the brand because I have no clue. But as mentioned doing 2-3 light coats helps.
    • no expert here, but heat doesn't rise. heat radiates in the direction of least resistance (R value). warm air or water rises because it is less dense than colder air or water.  If you don't insulate you will be heating the ground under your cabin and the earth is a very large heat sink $$$. get some info from an expert in the radiant field as far as tube diameter, spacing, water temp, manifolds, length of runs, and so on. it varies on amount of windows (solar) ceiling height and room type (bed, bath, living area,  storage etc.). once you pour over the tubing you get to live with it. I did my own Home 15 years ago and got some good advise (wish I would have taken it all)
