We have had tons of moisture , perhaps Buzz will chime in with some info.
I would suspect the area is recovering well but depends on the severity of the fire, how hot it burned.
This fire burned about as hot as a fire can burn, as would be expected given the drought and wind conditions that spawned it. fine ash goes down to mineral soil, I dug thru some 16-18" deep and hiked miles without passing a living tree or bush. Moisture aint gonna do squat here except cause erosion. This one is going to be a wasteland for quite some time. Even the burn from 2-3 yrs back re-burned which was a bummer as it was a "good burn" leaving a good mix of green/black behind.
Of course there are edges where this is not valid info, but the heart of this fire was brutal, best to look elsewhere in the near-medium future.
Back in the day re-seeding may have been attempted but given todays politics i doubt it.
