I have finally secured a copy of the 2013 Western Hudson Bay mark-recapture study produced by Environment Canada.
The pertinent figure is below: as you can see, there was no declining trend in Western Hudson Bay polar bears between 2000 and 2011. Click to enlarge.
I have relatives visiting so I don’t have time to do an in-depth summary but the report’s opening “Summary” is copied below and a pdf provided. More later when I have had time to look at it more closely. Background on the issue here.
Summary from the report, click to enlarge:
