Mated with wolves - humans had destroyed wolf habitats, so those populations moved

It’s the warmest part of the GLSL on the Canadian Shield, because:
- Most southern
- Lower elevation

- Yes

- Cloudy eyes indicate it’s going to shed its skin
- Small keels(?) on scales for grip
- Threatened in Frontenac Axis, endangered in Carolinian

Pitch Pine
- pine tree with large cones
- benefit from fire, but isn’t dependent on it

Why can calciphilic ferns grow in the Frontenac Axis?
Marble/crystalline limestone provide calcium
What does the A2A group do?
Try to maintain the forest between Algonquin and Adirondack
Name one animal that came to ON via the “corridor” formed by the Frontenac Axis.

Canadian Shield
