- •
We modeled spatial patterns of bark beetle-killed forest patches after a storm.
- •
Simulation models including beetle aggregation gave best fit with empirical data.
- •
Beetles used most of the windthrows the two first seasons after the storm.
- •
Later on new attack patches with hard-to-predict sizes developed outside windthrows.
- •
Removal of windthrows the two first seasons may prevent a patch-driven outbreak.
