Fisher research

We set out to determine why the fisher had made such a remarkable recovery in Ontario. We have used 2 radio telemetry studies, genetic studies, and assessments of live trapping and fur harvest data. Some aspects of the research are ongoing, but it appears that the fisher recovery has been largely driven by population growth in the southern portions of their range. In particular, we found considerable immigration into Ontario from Adirondack Park. More recently we have used our fisher genetics dataset in the development of landscape genetics analytical methods.
