Grey Squirrels are a danger to native plant and animal species. They often strip the bark from a
young oak tree and cut out the embryonic root in acorns they collect, preventing germination. They
feed on native lily bulbs, such as Camas, and are particularly dangerous to the fragile Garry Oak
ecosystems. As well, Grey Squirrels prey on nesting birds, eating bird eggs and nestlings. They raid
backyard feeders for seed and compete with native bird species for tree cavities.

Some folks quite enjoy them but others consider them foreign rats with fluffy tails and I'm afraid
I have to agree with them!
