Data gaps prevent assessment of most Canadian watersheds: WWF report

Spotty research and inconsistent monitoring have made it impossible to evaluate the health of most Canadian watersheds, a study has found. “It’s still largely unknown,” said Elizabeth Hendricks of the World Wildlife Fund, which has just released its second evaluation of the condition of Canada’s freshwater environments. Hendricks said the report points to the need for standardized, national water monitoring done by local communities.
