A mature pine forest must burn to renew itself. When it is not allowed to burn things like the pine beetle infestation occur. The fires in BC this summer consumed thousands of ha of standing dead trees. The worst environmental disaster in Canada, all due to poor forest management.

The trees around Banff have not burned in over 100 years. The folks in the city will have a coronary when Mother Nature sends in fire or beetles. 

Logging can be a substitute for fire. Maybe they should put some horse loggers to work in Banff to make it more palatable.
