General recommendations from operative worksite.

	Damage degree 1	Damage degree 2	Damage degree 3
Felling	Unproblematic (= fewer spores in the air)	Expected peak of spore production, uncertainty about hidden amount of spores under the bark (= protective measures strongly recommended)	Felling without bark after spore release (= no spore production without bark)
Processes after felling	Shredding, rotting on site in the undergrowth, combustion, removing of bark	steaming, burning on site, covered transport	high loss of timber value due to fungal degradation
Fire wood storage	Guaranteed fast drying of the split wood is important to prevent further fungal growth	not recommended	without bark possible but less value due to severe wood degradation
Protective measures for forest workers	Working during rainy periods with fewer spores in the air, wear filter mask	Felling should only be carried out under consideration of traffic safety and the risk of falling over. Mechanical felling, breathing or protective clothing, as the highest spore load is to be expected	Consider risk of breakage.
