How indigenous conservation protects Canada’s environment

In Canada, centring conservation with the country's indigenous peoples is allowing its original stewards to reconnect to their land and culture – and proving remarkably effective. Every year, when the frozen streams have melted and greenery emerges after months of winter stillness, Dolcy Meness knows it's time. Packing their truck, she and a colleague set off through the densely forested hills of Kitigan Zibi Anishinabeg territory, an Algonquin First Nation in the province of Quebec.

Saltwater lake in Kelowna losing salinity, putting rare ecosystem at risk

Saltwater lake in Kelowna losing salinity, putting rare ecosystem at risk

A fragile and rare ecosystem in Kelowna is changing forever as the community grows around it. Robert Lake, just south of the Glenmore landfill, is unique for the salt content in its water. It provides a refuge for birds and amphibians rare in the B.C. Interior. The lake has no outlet and used to completely dry up “quite regularly,” according to Ian Walker, the vice president of the Friends of Robert Lake Society and retired biology professor at UBC Okanagan. “You'd often go past and you can see these little roll winds of white salty dust kind of blowing around,” he said. But for the past four to five years that hasn’t happened and increasing water levels are creating problems for nearby property owners, the City of Kelowna and the animals that rely on the lake.

News Release - Government guidelines across North America, Europe fail to protect lakes from salt pollution human activities, including de-icing in winter

News Release - Government guidelines across North America, Europe fail to protect lakes from salt pollution human activities, including de-icing in winter

The salinity of freshwater ecosystems caused by road de-icing salts, agriculture fertilizers, mining operations and climate change is increasing worldwide and current water quality guidelines don’t do enough to address the issue, an international study led by Queen’s University and The University of Toledo has found. The research, conducted in collaboration with dozens of scientists across North America and Europe, shows significant damage is being done to freshwater lakes by salt concentrations that are below ranges government regulators have deemed safe and protective of freshwater organisms.

Warming ocean temperatures — especially in deep water — set more records in the Gulf of St. Lawrence in 2021, according to climate data released Tuesday by the Department of Fisheries and Oceans. "Everything about the Gulf of St. Lawrence was warmer in 2021," said federal research scientist Peter Galbraith, based at the Lamontagne Institute in Mont-Joli, Que.
