Ministry of Environment, biologist Christian Engelstoft and Hitomi Kimura, a biological technician at Vancouver Island University in Nanaimo; a second will contain Neville Grigg and Pattie Whitehouse of the Highlands Stewardship Foundation, a volunteer citizen group that promotes the health of local lakes; and a third will bear the interlopers — myself and photographer Deddeda.
