I have heard this figure before but can't remember what it is, but how many coyotes do you have to kill to actually hurt the population? I maybe way off based but is it something like you have to kill 70% or 80% of the population in that area to hurt them? any thoughts on this?

No, that's close to what I have heard, but I take it on faith. I assume those that do the research can back it up?
Good hunting. LB

Jeremy, there have been many studies conducted on control and suppression of relative densities. Each one produced a similar model.
Here are a few,
Pyle-1972 showed that annual kill rates of about 40% of the pups, 45% of the yearlings, 36% o the two year olds,26% of the three year olds,and 20% of the four to eleven year olds would hold the population steady. Seems like that would be hard to prove.
Sheriff-1976 found that mortality rates of 78% for pups and 50% for adults would reduce the population by 50% over 25 years.
Connally and Longhurst-1975 said that their coyote population could withstand an annual kill rate of 70% but not 75%. But even at 75% the population persisted for more than 50 years.
The manner in which the coyote recovers from low densities after control measures is astonishing.

thanks for the info Rich...that's pretty interesting stuff, any idea how big of area these studies covered?
