A new study paints a picture of what Haida Gwaii might have been like 57,000 years ago.
Rolf Matthewes is a professor of biological sciences at Simon Fraser University, and one of the authors of the study.
He says they made several discoveries about Haida Gwaii that they previously didn’t know.
By using a new technique, they now know when the second to last ice age over the islands took place.
They believe during that time Haida Gwaii was a treeless, tundra-like arctic climate by examining pollen grains in a peat layer.
Matthewes also made a major find in a peat layer.
He says he discovered a type of spore that colonizes animal dung, the first time it’s been seen on Haida Gwaii.
Those animals include large caribous and mammoths.
They also discovered pollen spores from plants that likely managed to survive the last two ice ages into the present day.
The study was released in the Canadian Journal of Earth Sciences, and was chosen as an Editor’s Choice.
