The big trees are exotics - redwoods, douglas fir, cypress, eucalyptus, etc - and were planted in the early part of the 20th century... There are still quite a few native species, as well... The place really looks and (because of the cool temps) feels more like a forest on the coast of Oregon or northern California...

You are right in that this might present an opporunity to plant native species... I may take a run up there in a couple weeks and take a look around...

Edited to add:

Here's a wikimapia link to the area that is burning (hope it works)... The clear area in the trees is the State Park and cabin... The fire burned around the cabin (the cabin was spared) and over into the area to the right (look for the switch-back road) and up to the skyline trail (the upper trail at the "Y" after the switch-backs)... You can use the sliding scale on the left side of the view window to zoom in and out...
