A lot of trappers mix up fur quality with the priming cycle.Two different things.

Just looking at the daylight differences on the shortest day of the year in the northern hemisphere misses the point that the animals have evolved to have their fur not only change in amount but type weeks if not month prior to the shortest day of the year. If they waited until the shortest day to grow a different set of fur things would have been tough for them. Those species or individuals that did not adapt earlier are not here today.

The credit goes to the creator not the creation. God is proactive and not reactive. Animals do not prime up when it is cold and will prime when it is still really warm. He gives them a coat before it is needed. LLL

Exactly ! Lets not conflate the priming process, which is triggered by decreasing daylight, With fur quality, which is governed by DNA and local/regional adaptations over centuries.

Got a question for those of you that went to college and got a lot of knowledge. How does available food affect priming? I can state this fact as it pertains to bears in Northern Maine. In years of short food supplies the bears prime up & fatten up sooner. When food is plentiful not so much. I'm basing this on 100's of bears killed over the past 10 years at the camps I've worked at. A few years ago we could not find a bear after Oct. 8 and had to cancel booked hunts. Last year the bears were still out @ Thanksgiving. This year (short food supply) the bears had lots of fat and very nice fur in early September. Last year with lots of food the bears had very little fat & very thin fur into October. I have cameras on baits and will report when the bears disappear this year.

Bear hides don't prime up until early spring.
Bears stay out longer in fall when there is still food available for them.
The quality of fur varies quite a bit from one individual bear to another.
From my experience of commercial hide hunting for about 15 years,smaller bears tend to have more coarse and wooly hides and rub a lot quicker in the spring.Older bears have silkier fur and hold their coats for a longer period in spring.
Bears that have some fat under the skin in the spring(these invariably are larger bears) tend to have a shorter nap than bears that have used up all their fat in hibernation.
One fall the bears all had some sort of a disease.Although there was a bumper crop of blueberries that fall,all the outfitters reported bears in poor shape with little to no fat.

I'll post a link to an interesting study concerning marten/bears in areas with lots of beech trees. The area I talked about (two posts up) is near the Spectacle Pond study area. For the past ten years I've worked at two different bear hunting camps in this area. The kill at these two camps varies from about 70 - 100 bears each year. Bottom line, even numbered years (lots of beech nut) = no fat (to speak of) & poor quality fur on the bears. Bears also den-up much later (6-8 weeks later). Odd numbered years (low beech nut production) the bears will fatten up quicker and have high quality fur at least a month sooner.

It is an excepted fact (with guides & local taxidermists) that during lots of food years the bears will have low quality fur during the Sep-Oct harvest season. The opposite is also true, during years of low food bears have a high quality fur during the harvest season.

I also wonder where all of the bears come from the hunting area is about 400 sq. miles and killing about 1500 bears there (past 20 years) seems like a lot of bears. I'll also add that the surrounding areas are also leased for bear baiting/hunting.

There is no debate.

Primeness is dictated by photoperiod.

It’s scientific fact.

Bear Marten Study



That's an interesting study. It's easy to sit here and pick it apart but It does raise some interesting questions.

What I DON'T like is in their discussion of marten harvest they say that litter numbers or survival may be greater following years of higher beechnut production....and that COULD lead to higher juveniles in the harvest. But they never provide any age/sex breakdown on the marten harvest.

Also, I think it would be good to look at changes or restrictions on methods and means of trapping marten. Are trappers restricted to certain types of sets, or baits, or traps ? That would be consistent from year to year if no changes in regulations or trapper effort occurred during that time.... but I can't envision any critter turning up its nose at a fat chunk of beaver and eating a beechnut by preference.

Where I really started to question the whole exercise was where they said the Huntington Wildlife Forest is located @ 74* 15' N x 44* 00' W. I don't think so !

It is the reduced amount of UV light that enters the eye of an animal that triggers the priming process. Primeness is dictated by many factors previously mentioned. Carry on!

Scientific fact: something that a government study funded and has been repeated so many times that people actually believe it. It is a fact that in areas of northern Maine SEP & OCT BEAR FUR QUALITY differs greatly year to year. Maybe all of the beechnuts create more shade and less light reaches the bears. These same shading beechnuts also affect weasels & snowshoe hares. That's all I have to say about that.

Fur QUALITY and fur PRIMENESS are two seperate things.

Fur can be PRIME, and of low QUALITY.

Temperatures, hot or cold, will not speed up nor slow down the timeline in which an animals fur primes.

Temperatures can speed up the decline of fur (damage wise) on the backside. Warm falls and winters, no or little snow almost always means damage starts to show up earlier and with greater magnitude, at least in canines.

Last year we were unseasonably warm through November and early December. No coincidence I started seeing some significant damage on Dec 10th. I was expecting it. When I should have been killing the BEST coyotes of the year, most were damaged to some extent. Prime, but quality was low.

Even if fur quality varies, that does not mean that the priming process has been altered. The available nutrients that an organism ingests definitely can affect hair quality. It will not affect available uv radiation.

Quality can be affected year to year greatly by outside factors. Notably, age of animal, nutrition, and genetics of the population.

Primeness is photoperiod.

So the photoperiod controls the rate of hair growth?

The photo period triggers the entire process. The RATE of hair growth could depend on the things Boone mentioned as well as latitude. An Alabama coyote probably does not experience the same RATE of hair growth that a MN. coyote does.

This is a fact: every other year (call it the beechnut effect) in northern Maine, Bear's fur grows longer & thicker, sooner. This happens in year's of LOW FOOD SUPPLY. It is obvious to those of us that operate there (N 46.5, W 68.5). Even Captain Obvious knows it. I'll add something else, during these years of low food supply the bears den-up early & the 'coon go with them.

Well IF that is in fact the case, then I would say something else is going on in that environment that has not been noticed. The apparent correlation with beechnuts may be nothing more than coincidental
