RE: Deer Travel 20 miles?
Deer yards are quite common in Ontario, as they are throughout the north.
We have a large deer yard near Loring in the Parry Sound district that was left as the only one viable in the area after a population crash and severe wolf predation in the early '60's. This deer yard has been known to hold as many as 25,000 deer, and distributes deer over a very large area - over a radius of 20 miles or more. In recent years some new yards have been starting up, so the size of this yard and distances travelled have been dropping.
