Summary of polar bear population status per 2010

A status table was first discussed and published at the 11th meeting of the PBSG in Copenhagen in 1993. The present table was discussed and concluded upon in Copenhagen in 2009, and some small updates on the comments was done in March 2010. The comments will be printed below the table when clicked.
