This is a magnificent short video on the Fraser River courtesy of Dr Marvin Roseneau of SFU and Mark Angelo of BCIT. It is really a must see for youngsters as well.
From the BCIT Rivers Institute on the Heart of the Fraser initiative, one of Canada's most important conservation campaigns aimed at protecting one of the most productive stretches of river on Earth. This particular story focuses on a quest for knowledge - and the applied research now taking place aimed at quantifying the values of key off-channel habitats along this stretch.
