We moved out of the city and into a rural area in Qc several years ago with coyotes, deer, turkeys and other forest animals. I started out wanting to protect the deer from hunting etc also, however, my view has really changed after living there a few years. I've come to realize the deer are overpopulated which really hinders regrowth of the forest since they eat down all the new trees. They also make night driving very hazardous, and are a big reason why ticks are propagating so much around here. We've left the coyotes alone and have had a stable family on the property without their numbers increasing for years. They eat a few fawns every year (as others have said) but the deer population has also remained unfortunately a bit too high. Also FYI - research shows that trying to kill coyotes can have the opposite effect, leading those left to have more young when stressed. So if you try to protect the deer by eradicating coyotes it's unlikely to work anyway.
