Acknowledgements and Authorities Contacted

I would like to thank all the people who offered Western Painted Turtle records to museums or agencies over the years; particularly significant contributions were made by Mike Oldham, J. Bakowski, and Jeff Robinson in Ontario, Mike Sarrell in B.C., and Dana Shock in Saskatchewan.  I also appreciated the support of all government employees, especially those who were contacted repeatedly: Mike Oldham (Ontario’s NHIC), James Duncan (Manitoba CDC), Jeanette Pepper (Saskatchewan CDC), Richard Quinlan (Alberta Species at Risk Program), Marta Donovan (B.C. CDC), Laura Friis (B.C.’s central MWLAP), and Ross Clarke (B.C.
