Bizarre clip shows Quebec forest ‘breathing’

“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,” arborist Mark Vanderwouw told The Weather Network.

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.”
