Do cows drive off wildlife?

[Gammaboy]

I farm part of a quarter where 90 acres have never been broke. Hills, ponds, beavers, poplars throughout. Beautiful piece of scenery but not real useful to me outside hunting season.
Cows were pastured there till the 80's and its been idle since.

Sandy, hilly land north of Blackfalds where it "always" rains. If it gets refenced and grazed in the spring-fall will the cows drive the deer and moose away or do they co-exist?
(I'm not a cow guy, just looking to answer landowners questions).

Thanks
