I suspect the black-backeds could be there before the wood cools.
Certainly within a few months. In my experience, in Washington it's the
black-backeds that are most burn dependent, with three-toeds far less
partial to such adventitious habitats. I know of some burns that stayed
active with black-backeds for 3-5+ years, though the timing is likely
more influenced by how long it takes the salvage loggers to move in.
