Interaction between the probability of collapse of different forms of hollow-bearing trees between 1997 and 2015 and the amount of fire in the surrounding landscape.

<p>The probability of collapse of trees in forms 6–8 increased with increasing amount of burned area in the surrounding landscape, whereas the probability of collapse of other tree form categories remained relatively unchanged with the increasing amounts of fire. The amount of harvesting is set at the mean value in the landscape.
