This propublica story has a lot of detail on the fires. They estimate that there are ~20 million acres overdue for burn and the fires this year are burning about a million acres. If I understood it correctly a million acres burning a year is about what's required for stasis, but the 20 million acre backlog will need to be burned too.

At this point over 3 million acres [1] have burned in CA alone. So, seems like some of the 20 million acre backlog is getting burned through this year.

OK, so in three equivalent years, 50% of what needs to go will be gone - and that will give "herd immunity" to the unburned parts - 'till those get large again, say in 5 more years.
