Seismic Lines Helped Butterflies Survive Fort Mcmurray Wildfire, Study Shows

Even as Alberta’s fierce wildfire raged in and around Fort McMurray in 2016, plants and butterflies were surviving in narrow strips of forest that remained green and undamaged.

Even as Alberta’s fierce wildfire raged in and around Fort McMurray in 2016, plants and butterflies were surviving in narrow strips of forest that remained green and undamaged.

Seismic lines, used to locate underground oil reserves, provided refuge from the blaze, said University of Alberta researcher Federico Riva, who outlined his recent findings after studying the area a year later.

Because the cleared corridors provided little fuel for the fire, they stayed almost intact, allowing plants and butterflies to survive “even when the surrounding forest was almost completely burned,” said Riva, a post-doctoral fellow.

Of 107 plant and 46 butterfly species Riva observed, most were found to be more common in these corridors than in the neighbouring scorched forest,where fire had substantially reduced their abundance.
