Out of control wildfire in Willmore

There is currently a fairly large wildfire burning in the back side of Willmore. They are currently fighting it from the air. Just wondering if anyone on here would know why on earth they are bothering to fight it rather than letting it take its course. I thought wildfires in the park not directly threatening Grande Cache on the west side of the park would be left alone? Do we have to put out every fire in the province? even in the Willmore. Doesn't make the least bit of sense to me but perhaps someone can fill me in on this one.
