Seal River Watershed: The case for conservation

The Seal River Watershed in northern Manitoba is a 50,000 km2 area that is 99.97% intact and serves as one of Canada's largest free-flowing drainage basins. The report highlights its critical role in biodiversity, storing 1.7 billion tonnes of carbon and supporting species at risk such as polar bears and barren-ground caribou. Economically, the watershed provides at least CAD 214 million in annual ecosystem goods and services (EGS), including ecotourism and caribou harvesting, while the stored carbon is valued at CAD 314.5 billion. The document advocates for the creation of an Indigenous Protected Area (IPA) led by the Sayisi Dene, Northlands Denesuline, Barren Lands First Nation, and O-Pipon-Na-Piwin Cree Nation to prevent threats from mining, hydroelectricity, and road development. It suggests the Manitoba government implement interim protections, establish a feasibility committee, and provide technical support for Indigenous Guardians programs.

• The Seal River Watershed is an exceptionally intact ecosystem, with 99.97% of its 50,000 km2 area remaining unaltered.
• The watershed is a critical biodiversity hub, supporting an estimated 250 bird species and 350 other taxa, including 48 mammal and 26 freshwater fish species. It provides a summer refuge for over 16,000 beluga whales and is essential for the Qamanirjuaq barren-ground caribou herd, which has seen numbers decline by 2% annually since 2008.
• The watershed acts as a massive carbon sink, storing approximately 1.7 billion tonnes of carbon (equivalent to 6.2 billion tonnes of CO2), which is roughly eight years of Canada's total 2018 greenhouse gas emissions.
• The annual economic value of ecosystem goods and services (EGS) in the watershed is estimated at a minimum of CAD 214 million. This includes CAD 10.97 million from ecotourism, CAD 9.56 million in mental health benefits, and CAD 192 million for the conservation of beluga whales, barren-ground caribou, and northern pintails.
• The monetary value of the CO2 stored within the Seal River Watershed is estimated at at least CAD 314.5 billion, a figure exceeding the GDP of Manitoba by more than four times.
• Proposed developments pose significant risks to the watershed: an all-weather road could disrupt caribou migration and increase wildfire risks; the Kivalliq Hydro-Fibre Link transmission line would disturb wildlife; and hypothetical hydropower diversion could flood 39 km2 of forest and release methane.
• Indigenous Protected and Conserved Areas (IPCAs) are defined as lands and waters where Indigenous governments lead protection through their own laws and knowledge. The report notes that IPCAs often have a higher likelihood of long-term conservation success than other models.
• The report recommends the Government of Manitoba take three specific actions: implement interim measures to protect the area from commercial extraction (such as withdrawing mineral staking), establish a feasibility committee for the IPA, and provide technical support for Indigenous Guardians programs.
