supplemental feeding

[werner.reiche]

Once one is infected and feeding in the same lot chances are the others follow as it's transmitted through its saliva and other body fluids that's all around.

Even without overpopulation this can wipe out a heard in no time once it begins. You can have a sick buck breading with a few does and won't even see a problem for 2 years. Luckily it's not very established yet but it is moving north.

The disease could of originated from overpopulation but it spreads the same as any other virus close contact

CWD isn't a virus. It's a prion. Compared to other diseases, it's not very infectious. It needs to be ingested to pass the infection to another host.

I'm not too afraid of it up here. The problems with CWD and deer feeding are:
a) it increases the deer density - bad for any disease
b) use of feeds like carrots, apples and sugar beets which the deer bite pieces off with the remainder dropping to the round covered in deer slobber *could* spread a prion based disease through saliva when another deer easts that part.

If you're supplemental feeding hay or grain, part b is not such a worry.

I'd think that mineral licks would be a far greater problem for saliva exchange than supplemental feeding though.

Re: the standing water issue - the only reference I found to this is related to deer farming - where deer are drinking the water other deer have peed in. Likely not an issue with wild deer.

Thanks for the clarification... .

look at harvest rates from WMU's that did supplemental feeding from back then to now and it paints a pretty clear picture
the Looring yards used to be one of the premier places to hunt not even close to that now.

The decline of the Loring yard is not just due to the demise of feeding. In the 60s, 70s and 80s there was extensive management of the woodlot to promote ideal yarding conditions above and beyond any supplemental feeding. Prior to its creation the area was almost a "deer desert."

Unfortunately, the MNRF is no longer a hands-on agency. Nowadays, deer are managed by way of licensing, season length, and antlerless quotas. There used to logging guidelines to manage moose and deer but those have been watered down to nothing.

Generally speaking, deer can thrive on most summer range but game managers have forgotten about the importance of quality winter habitat.

There's not a wildlife bio out there that suggests winter feeding unless dire circumstances.

As far as supplemental feeding in the past and more deer, I would guess there wasn't near the coyote population back then.

Where we are, the deer head to the yards around mid December, at or near the end of bow season. Due to the early onset of spring, they are already showing up on our property. Over the past week, I have seen mature deer tracks and one set of fawn tracks near my shrub cherries.
Fawns are less particular about what they eat. They go after my blackberries, raspberries, shrub cherries, elderberries and my wife’s hostas - they love hostas and will chew them off right to the ground.
I also find evidence of deer browsing on the small twigs of my apple trees..I have taken to planting a small foodplot at the back of my property and now have a nice patch of clover that they seem to enjoy, but their favourite are the small wild white turnips. This year I going to try a different mix with turnips and beets. The clover is already well established.
