Beavers have been mowing down trees in the artificial spawning habitat on Burnaby's Byrne Creek. While the Byrne Creek Streamkeepers are all for urban biodiversity, we felt we had to protect the trees in the habitat that provide crucial shade for the spawning channel in the summer, so we had a tree-wrapping session this morning. We use chicken wire, and it's effective in keeping Canada's national symbol at bay :-).

A view of some of the damage.

Here I am going at it with chicken wire and cutters.
