Pukaskwa National Park's encouraging people to help discover the diversity of species in the park over the next day.
Visitor Experience Manager Amy Mackey explains a "BioBlitz" will be held to find and identify as many species as possible.
Mackey says Pukaskwa's first BioBlitz (in August 2018) focused on a small section of the park's "front country".
Mackey emphasizes that the BioBlitz doesn't mean any closures for the park - in fact, people are encouraged to come out and participate, joining in hikes with experts and learning about the park's biodiversity - even if you've been a longtime visitor.
The BioBlitz runs from 12 noon today (Tuesday, July 9th) to 12 noon tomorrow (Wednesday, July 10th).
