I agree with bigbulls, ticks may have devastating effects on the moose population especially in drought years when there is less water for the moose to keep the ticks off of them. In my region of saskatchewan the moose have died out really bad over the last 3 years. 2 years ago while shed hunting my friend and i discovered 5 dead moose dead in fenclines within a 3 mile radius of my farm. One died so close to my farm we could smell it when there was a south wind. It just looked like these critters had layed down to sleep and never woke up. How many were dead that we never did find? As a result they lowered the hunting pressure on the moose here but its still not enough, the rifle season should be closed down completely. I remember when i first started trapping in the spring which was about 6 years ago, i could not go a day without seeing a moose in the river flats where i trap. For the past 2 years i have only spotted 1 moose on my land. I am not to say that wolves will not take a moose down but most likely these moose have died of ticks or they have been weakened enough by the parasites that they become an easy prey for the wolves. If the wolves would not prey on a tick infested moose the mooses survival would still be very questionable.
