In the first picture, you see some curling on the ends of the branches of some bigger trees:
In a driven crown fire, the ends of green branches on bigger trees will curl from the intense heat before the foliage actually burns.
Also, you see a lot of younger trees blown over with rootwads still attached - you see that a lot in running ground fire in conjunction with a
driven crown fire - blowing younger trees over in the direction the fire's headed.
On the soil - you see several areas in those pictures where the top of the soil is very clean with newly green patches popping up where water
has collected - there are two or three species of Lichens that begin growing immediately in carbon-dense, nutrient poor top soil that's been
partially sterilized by fire, after heavy rains. You see a lot of that in stand replacement fire areas in the northwest.
That's why I mentioned planting Ceanothus and Salal - these are Nitrogen-fixing plants that grow well in nutrient poor, carbon-dense soils.
Manzanita is a good soil stabilization shrub. Manzanita and Pacific Madrone also promote a forest floor symbiotic relationship with mycorrhizas -
beneficial fungus types which exchange nutrients with several conifer species.
