Flathead River Valley

One of the most biodiverse ecosystems in North America, the Flathead River Valley is a Noah’s Ark of predator-prey relationships.

Tucked away in the southeastern corner of British Columbia, in the traditional territory of the Ktunaxa First Nation, the valley remains one of the last wild river-basins in Canada.

The Flathead River Valley is a cradle for many species, like the grizzly bear, who have lost habitat elsewhere. It is a wildlife refuge rich in plant species and it’s the last piece needed to complete the Waterton-Glacier International Peace Park.

As global warming impacts multiply, the Flathead will also serve as a key component of the international wildlife corridor stretching from the Yellowstone National Park to the Yukon through BC.

“I’ve spent the past 35 years visiting the great mountain ranges of the world. I can say without exaggeration that the Flathead River Valley in B.C. is something truly special.”  — B.C. mountaineer Pat Morrow (the first person in the world to summit the highest peaks on all seven continents.)

Thanks to the help of more than 15,000 Friends of the Flathead, we’ve managed to get a ban on mining and energy development in the area, but it’s still threatened by plans for industrial logging, new road access, decorative rock quarrying and trophy hunting of grizzlies.

Let’s connect and protect it!

Creating a Flathead National Park and Wildlife Management Area is more urgent than ever before, as the range of many plant and animal species shifts due to climate change. It’s time to follow Montana and Alberta’s lead and connect the Flathead to the Waterton-Glacier International Peace Park.
