Cover Story: Key combinations of topographic elements in rugged mountainous terrain of the Canadian Rockies support the formation of persistent fire refugia, where forest stands can survive multiple fires for centuries. In this example, high elevation, north facing slopes within side gullies and a large component of non-fuel (rocks) enabled stands to survive fires from 2016, 2001, 1926 and 1768. The origin of fire refugia patches is estimated to be prior to c. 1700. View the paper here.
