There are not many trees out on the Prairies except within cities, so places like Regina and Winnipeg still have lots of big old elm trees.

I looked through this thread again because of your post in the Canadian Neighbourhoods thread... and just a small correction... The beetles that spread Dutch Elm disease can fly, so the wrapping would do nothing to deter them (instead there is a moratorium on individually transporting firewood through or into the city).
What it does combat though are canker worms. In the spring the canker worms crawl up the trees into the canopy and feast on the leaves, then they string down and hang from the trees. So it's a pest in that it destroys the canopy, but also makes the infested area impossible to walk through without getting a face full of the sticky threads. The only problem is if just one person doesn't wrap their tree, the worms can infest all because the canopy is pretty much completely connected.
Definitely enjoyed looking through your photos again though. Might have to make a trip around this neighbourhood in the summer when the trees are in full effect.
