In the eastern Mediterranean, tree rings tell of a shift toward stand-replacing fire?

In a Greek forest, tree rings telling a familiar story – a history of surface fire, but a trend toward much more destructive blazes:

the size of the area burned as well as the type of fire seem to have changed, with the 2007 event being the most extended crown fire encountered so far. Our study has provided additional evidence that P.nigra is indeed a fire-resistant tree species provided that it is exposed to surface fires, even if they are recurrently occurring. Shifts from this pattern may lead to local extirpation of the species, as in the case of severe and extended crown fires.
