How might drought-stricken forests impact Canada’s fall colours?

Canada’s signature fall foliage might not have the same vibrant pop this year.

After a hot, dry summer, many trees are stressed and their leaves are already turning brown.

Instead of transforming into brilliant reds, yellows and oranges, some may simply drop early.

Biology professor Susan Dudley from McMaster University says drought stress isn’t the only factor. Chemicals in wildfire smoke can also cue leaves to die sooner, adding to the duller display.

But there’s still hope. If September brings cooler, rainy days followed by a bright, crisp October, experts say we could still see some of the spectacular colour that draws people outdoors each fall.
