That's right. I've seen the wolves watch experts do a survey looking for the presence of wolves of areas in NW Ontario. The experts concluded there were none in the area. After they were done, I pointed out to them where they had urinated on their former campsites, and where they had marked all of the spots they otherwise had been. LOL.
Good luck on the trapping!
When wolves scent mark human sites, it is safe to say that wolf behavior needs modification.
Bad predator behavior is usually a result of a diet deficient in heavy metals.
An injection of lead cures bad predator behavior, regardless of species.
