The "Breathing" Forest

Check out this video of a forest in Sacre-Coeur, Quebec, Canada, that shows how heavy winds make the forest floor looks like it's breathing.

The Weather Network interviewed arborist Mark Vanderwouw who explained:

"During a rain and windstorm event the ground becomes saturated, 'loosening' the soil's cohesion with the roots as the wind is blowing on a tree's crown," he said.

"The wind is trying to 'push' the trees over, and as the force is transferred to the roots, the ground begins to 'heave'. If the winds were strong enough and lasted long enough more roots would start to break and eventually some of the trees would topple."
