A study at Logan had some interesting results. If up to 60% of a coyote population was removed- it would take 1 year (until pups were raised) to get the population back to pre harvest levels.
If 60+ % of the population was removed, it took 2 years.
If 70+%, 3 years.
If 80+%, almost 4 years and if 90+% it would take almost 5 years to get back to pre harvest levels.
The study also concluded that to reduce the population over 70% was logistically improbable, because the territorial boundarys break down and normal pattens no longer occur.
The study alos detrmined that from 15-35% of a given coyote population was non territorial.

Boy does that answer a lot of questions.

Yes- so that might be the couple you take right away...and those tracks that hang back are the homebody....

Here I go again p-----g and moaning about our defunked coyote snaring program in Maine! The biologist had told us that to reduce the coyote population you had to eliminate 70% every year. Year after year. It was obvious with our vast woodland that this never could be accomplished. Not to mention all the stumbling blocks the biologist and do gooders tossed at us! The program under animal damage control was set up to help the deer herd in areas that had low and falling populations of deer. Northern, Eastern Maine mostly. Southern Maine Is over run with deer. Many biologist where against the program and when the season was over they would toss this 70% Information to the public that our efforts where doing no good what so ever. They never showed how snares like Dan Glidden or Dave Toby and many others where getting 50 to 100 plus coyote each. Sometimes out of just one deer yard.
In Maine the PRO wolf group want to reintroduce the wolf to the area. I say we already got a better wolf living here. He came un protected , hunted and trapped as he spread out through the state, it’s proven he has wolf DNA in his makeup. A Canadian study points to possibly being interbred with their Lorintide (SP) wolf. A member of the red wolf , or off shoot of the red wolf?? They sudgest that this may be why the eastern coyote seems to prey on deer more than his western cousin?? Somehow the early residents drove or eliminated the wolf from the state In a matter of a short time. With all our knowledge , skill and modern equipment. We could never drive the coyote out I don’t believe. But don’t I like to see one of those 40+lb.ole boys fighting a trap or wrapped around a sapling with the snare jussssst behind his ears!! Get all hot and bothered just thinking about It!

, They sudgest that this may be why the eastern coyote seems to prey on deer more than his western cousin?? Hornhunter, I am in agreement with all you are saying. Could the quoted statement above be 'cause the eastern 'yotes are much bigger ? Just curious. Paul

Paul, I thought the eastern ki-yute was a smaller version of the timber wolf I remember reading that somewhere. that's why they are bigger then them western ones. ;D

"They sudgest that this may be why the eastern coyote seems to prey on deer more than his western cousin"
In my area it is because the yotes ar able to use snowfall to their advantage.
Wheres my original post?

They do that in NH too Edge, in the spring when you get a few warm days to put a crust on the snow, the yotes run on top, the deer ( especially pregnant does) are easy pickins, they and domestic dogs put a real hurtin on the deer at that time of year, so much so, that there was a law when I lived there that said anyone who witnessed a dog in the act of running deer could shoot the dog on sight.

so would the 15 to 35% that are nonterritorial nomadic?
or do they stay in a core area but not mark it/defend it as territory?

woody,
I honestly don't know if this is so or not.
Some of the 'yotes up here get some size to them.
Would be interested to know.
Does anyone have any facts on this ?

the way I understood th study is that these cooytes wer nomadic...but that doesn't mean they were constantly on the move. kind of drifters to use the cowboy slang..here a few days...there a few days...
kind of like we were before the wife, kids....LOL

But are they different strains ?
And why the wide range of color variations ?
Sure would be interested in knowing.

Wiley once told me this would make a very interesdting Masters thesis- the dna of cooytes in last 200 years.
Enough Indian furs, etc available from them to provide a base...
any takers?

Post by dj88ryr on Jul 7, 2004 21:33:05 GMT -6
I am sure we have a diverse enough group here that could provide enough furs from enough different areas for todays yotes, you could probably get some Indian Furs donated for the cause, the only question is, who has enough money, or the connections to get the DNA testing done?

trappnman,
Not here.
Once was enough and that was 35 years ago !!
Sure would make an interesting study though.

I for one would love to see the difference in the coyote dna in Edges part of the state where there have traditionally always been coyotes and my area where the coyote is a newer arrival
there have been studies of the bobcats in both areas and they have been found to be different, enough so that it can be determined where the cat came from by the DNA, very useful in cases against poachers.

I don't think the studies are siding with a true timberwolf as being the wolf/coyote mix. the timberwolf Is a moose hunter. The red wolf preyes on deer. Lack of the orininal dna from the wolf that Inhabitted Maine Is a problem with Identification. I'd have to find the article again to make sure, but I think the wolf they refer to Is called a Canadian wolf?? Bob Noonan had a story in Maines Nothern Sportman's Journal called "Coyote soup" Or something like that?? he was In canada At an auctin house I think It was. He was told some of the small wolves where actually Coyote, And some of the large graded coyote where actually wolves. Maines report tells of a 25 lb. coyote having mostly wolf dna, and an 80lb. coyote having mostly coyote dna??

Hornhunter,
So am I correct in understanding you to say they are interbred ?
Would that be possible and with what strain of wolf ?
Help me with this please.#nosmileys

So size isn't going to determine anything, but the color variations must have something to do with ancestry and breeding pedigree.
