Thankfully, the one large community was Prince George. Its whole urban forest was lodgepole pine, and it all came down in about the year 2000. I remember the logging trucks sitting in the town as they were carting away, literally, the urban forest to the mill.
The key there is to replace them, obviously, with another species. Stopping that infestation is really difficult. I don't know. It's on such a huge scale that it's really difficult. I can't even provide advice as to how to do that, to be honest. I'm sorry.
