On a walk in Edmonton’s river valley, I came across a large poplar snag. It had most of it’s bark sloughed off, and was riddled with insect holes. So many would think this wood is dead and useless.
But oh no, on the contrary, it is alive, and plays such a vital role in the ecosystem.
Insect larvae live here, woodpeckers forage here and build cavities, owls nest here, and flying squirrels roost here.
Next time you see a cavity in a snag, walk up to the tree and knock on it – you never know who might pop his head out in surprise.
