Figure 4-2: Average trees per acre per diameter class within areas proposed for 

 harvesting in the proposed Fish Creek Salvage. Diameters presented are the 

 midpoints for a range of diameters (e.g., 8 inches dbh for 7 < dbh < 9).

4.3.3.2.1.2 Cumulative Effects of Alternative A: Deferred 



Harvest (No Action) 



Post-fire, there are currently an average of approximately 3.43 snags 

 per acre >21 inches dbh, which could serve as potential nesting and 

 roosting structures for pileated woodpeckers. However, because this 

 species generally prefers to nest and roost in late successional forest 

 structure, the current conditions within the project area may not 

 approach suitable conditions for pileated woodpeckers for at least 40 

 years. Additionally, the prevalence of the seed tree/shelterwood 

 silvicultural prescriptions on surrounding private industrial lands had 

 already reduced the availability of pileated woodpecker habitat in the 

 landscape, prior to the fire. Alternative A: No Harvest (No Action) 

 would merely promote an increase in available foraging substrate for 

 pileated woodpeckers, as standing snags (wood-boring beetle larvae), 

 and as coarse woody debris (carpenter ants) once snags begin to 

 topple. Thus, there would be low risk of cumulative effects for 

 pileated woodpeckers as a result of Alternative A: No Harvest (No 

 Action).
