New Map Shows Dramatic Time Lapse of Tar Sands Deforestation

A time-lapsed map released today by the World Resources Institute using satellite imagery from Global Forest Watch shows how much forest is being lost in Northern Alberta to make way for major industrial operations, mainly to extract oil from the tar sands, also referred to as the oilsands.

According to the data compiled by Global Forest Watch, industrial development and forest fires in Canada's tar sands region have cleared or degraded almost 2 million acres (775,000 hectares) of boreal forest since 2000.

The pink regions depict forest loss. Watch what happens at year 2010:

The World Resources Institute and Global Forest Watch have been researching the world's boreal forests since 1990. According to their research, Canada holds the vast majority, 54 per cent, of the world's total boreal forest across a region of 500 million hectares or 14 times the size of California. Boreal forests hold twice as much carbon dioxide as tropical forests. 

Another map shows tree loss in the tar sands region between 2000 and 2012.

Another year of keeping a close watch
Here at The Narwhal, we don’t use profit, awards or pageviews to measure success. The thing that matters most is real-world impact — evidence that our reporting influenced citizens to hold power to account and pushed policymakers to do better.

And in 2024, our stories were raised in parliaments across the country and cited by citizens in their petitions and letters to politicians.

In Alberta, our reporting revealed Premier Danielle Smith made false statements about the controversial renewables pause. In Manitoba, we proved that officials failed to formally inspect a leaky pipeline for years. And our investigations on a leaked recording of TC Energy executives were called “the most important Canadian political story of the year.”

As the year draws to a close, we’d like to thank you for paying attention. And if you’re able to donate anything at all to help us keep doing this work in 2025 — which will bring a whole lot we can’t predict — thank you so very much.

Will you help us hold the powerful accountable in the year to come by giving what you can today?
