On World Water Day, the Canadian Parks and Wilderness Society (CPAWS) is amplifying the call to save Lake Winnipeg by highlighting the fundamental need to ensure the nutrient filtration capacity of boreal forests and wetlands is a primary consideration in land use decisions within its watershed. As approximately 75% of the water that enters the lake is initially filtered through the boreal forests and wetlands of Manitoba, maintaining these ecosystems is key to meeting the provincial target of a 50% reduction in the phosphorous that plagues the lake.
