Tubing Damage Study


Please have a close look at the thirteen colour photographs presented.  Many of them represent damage by different wildlife species; others likely represent different examples from the same species.  We have purposely not labelled each example with the wildlife species that caused the damage because in most cases, we do not have definitive proof.  This is precisely why we will be looking to various wildlife experts in different agencies in Ontario to provide us with their expert opinions.  As you know, in most cases it is extremely rare to actually encounter the wildlife species creating the damage.

If you have tubing with a different type of damage, please contact Bob Gray at
