My college years were spent in S. Dakota. The antelope population was quite good.....winters there can be terrible but I don't remember a big kill off from weather or coyotes. Fences can be a problem, unlike deer which can jump over a fence, a antelope tends to go thru or under.

They are fast..........

Hope the planting, works out.
