Western Red Cedar 



Some average deductions for cedar: 



Spike tops - 1-2 logs in old growth and 8' in 

 2nd growth. 



Schoolmarms - 1-2 logs below fork in old growth, 

 8' in 2nd growth. 



Knees 



Butt Rot 



- Indicate rot extends 1 log up and 

 1 log down from knee. (Generally 

 joins other defect either above or 

 below in tree. 



- 1-2 logs in old growth, 

 growth. 



8' in 2nd 



Defect in old-growth stand determined by: 



A. Tree vigor as indicated by: 



1. Bark appearance 



2. Crown foliage (color & amount) 



3. Top (dead spike or alive) 



4. Limbs - cluster of dead ones 

 in green crown. 



B. Hollow Butts - These may be determined by 

 sounding with ax, or seen through open 

 cracks . 



G. Schoolmarm tops & deformed trunks. 

 D. Cat faces (Fire Scars). 



Defect in second-growth stand determined by: 



A. Hollow Butts - Defect usually plays out in 

 about 8". Sometimes takes whole tree if 

 tree vigor is unusually poor. 



B. Schoolmarm tops, deformed trunks, spike 

 tops. Deduct from 8' to 2 logs, rarely 

 whole tree. 



C. Cat faces, defect generally plays out within 

 a few feet of exterior sign. If a cedar is 

 vigorous, it will outgrow a cat face quicker 

 and with less loss than our other species. 



Notes on Cedar, plicata 



Best old-growth cedar found on good, moist, well-drained sites. 

 Rot is greatest on trees occupying low, flat, poorly-drained sites. 

 The age of the trees is also an important factor regarding rot. 



Old-growth climax stands are nearly always heavily infected with 

 Poria weirii (yellow laminated rot). The fruiting body is located 

 near root collar and is very hard to detect. Because conks are diffi- 

 cult to detect, rules for deductions on this basis cannot be made for 

 cedar. This rot often causes the hollow butts of cedar, often runs 

 into the second log and sometimes extends throughout the tree. So 

 severe are the losses, caused largely by this fungus, that some climax 

 stands (over mature) have been found to be about 65% defective on the 

 stump. 



Rot, in old-growth cedar that is forked within 30' of the butt, 

 nearly always extends to the ground. 



Defect will generally run 1-2 logs past exterior sign in old 

 growth and 4-8' in second growth.
