white sturgeon Fraser River

The battle to protect the heart of the Fraser River

Considered one of the most productive channels in the world, the lower Fraser and its unique islands provide important nurseries for juvenile fish, including endangered Chinook and prehistoric white sturgeon. But these islands are being bought, logged, diked and developed at a pace scientists and conservationists fear will upend the entire ecosystem

At 1,375 kilometres, the Fraser River is the longest in British Columbia. Much of the province’s population is situated along the river’s meandering basin. 

Its waters are home to countless species, including the prehistoric white sturgeon. 

The 80-kilometre stretch between Mission and Hope, known as ‘the heart of the Fraser,’ is one of the most productive river channels in the world.

Yet the small islands in the heart of the Fraser, known as island nurseries for juvenile fish, are being logged and developed for agriculture in a manner scientists fear could be the undoing of this unique and fragile ecosystem. 

This collection of photos is curated from the newly released book, The Heart of the Fraser, by Ken Ashley, director of the BCIT Rivers Institute

The book, which includes a collection of essays, outlines the importance of this stretch of river for locals residents and Indigenous communities who are already witnessing the impact of climate change in its waters.

Large, clear pools of water pools can become disconnected from the river’s main stem during winter months and serve as important spots for juvenile fish. This particular patch of water is hemmed in between a logged island and the TransCanada highway. Photo: Fernando Lessa

Chinook Fraser River

Chinook salmon (Oncorhynchus tshawytscha) are the biggest species of Pacific salmon. The Fraser River watershed is known for being the largest producer of Chinook in Canada, but due to overfishing, habitat loss and climate change, their numbers are diminishing. Of the thirteen wild Fraser River Chinook salmon populations assessed by DFO, only one is not at risk. Photo: Fernando Lessa

You’ve read all the way to the bottom of this article. That makes you some serious Narwhal material.

And since you’re here, we have a favour to ask. Our independent, ad-free journalism is made possible because the people who value our work also support it (did we mention our stories are free for all to read, not just those who can afford to pay?).

As a non-profit, reader-funded news organization, our goal isn’t to sell advertising or to please corporate bigwigs — it’s to bring evidence-based news and analysis to the surface for all Canadians. And at a time when most news organizations have been laying off reporters, we’ve hired five journalists over the past year.

Not only are we filling a void in environment coverage, but we’re also telling stories differently — by centring Indigenous voices, by building community and by doing it all as a people-powered, non-profit outlet supported by more than 3,300 members

The truth is we wouldn’t be here without you. Every single one of you who reads and shares our articles is a crucial part of building a new model for Canadian journalism that puts people before profit.

We know that these days the world’s problems can feel a *touch* overwhelming. It’s easy to feel like what we do doesn’t make any difference, but becoming a member of The Narwhal is one small way you truly can make a difference.

We’ve drafted a plan to make 2021 our biggest year yet, but we need your support to make it all happen.

If you believe news organizations should report to their readers, not advertisers or shareholders, please become a monthly member of The Narwhal today for any amount you can afford.
