"An exhaustive federal study of Canada's largest national park concludes almost every aspect of its environment is deteriorating.
The 561-page report on Wood Buffalo National Park says industry, dams, climate change and natural cycles are sucking the watery lifeblood from the vast delta of northeastern Alberta's Peace and Athabasca rivers.
It was prepared after concerns were raised over the park's UNESCO World Heritage status and backs most of them up.
"The (Peace-Athabasca Delta) depends on recharge of its lakes and basins in order to retain its world heritage value," concludes the study released to The Canadian Press.
"Currently, hydrologic recharge ... is decreasing. Without immediate intervention, this trend will likely continue and the world heritage values of the (delta) will be lost.""
