280 METHODS OF TIMBER ESTIMATING 



REVERSE SIDE OF BLANK 

 Forest types, Lower slope 

 Age classes, 1-60 

 Condition of timber, Immature 



Thrifty 95 per cent 



Mature 2 per cent 



Decadent 3 per cent 



Fire killed per cent; damaged, 5 per cent 



Insect killed per cent; damaged, - per cent 



Other killed per cent; damaged, 2 per cent 



Name of disease, Bark disease 



Species affected, Chestnut 



Quality of timber (give by log grade; percentage of tall, medium or short clear boles; 

 or number of clear logs of stated minimum length and diameter): 



80% tall; 15% medium; 5% short 



Logging factors: 



Undergrowth; light-medium-dense, Light 



Windfall; light-medium-dense, None 



Bowlders and broken rock; numerous; occasional; absent, Absent 



Other factors, Easy gradient. Logging conditions ideal as skid and wagon 

 roads can be constructed anywhere 



Replacement: Species Per cent 



No replacement, 



Ground one-third stocked, 



Ground two-thirds stocked, 



Ground fully slocked, Chestnut, 50%; white, 5%, red, 5%, 

 black, 20%, and chestnut oaks, 10%; white, 1%, 

 pitch, 2%, and scrub pines, 2%; gum, 2%; sourwood, 

 1%, and maple, 2% 100% 



The stand shows an absence of poplar due to grazing 



Additional Notes: This is a stand which was cut over for charcoal during the war 

 and since then was culled for chestnut ties and poles. Bark infested chestnuts 

 should be cut as well as suppressed chestnut for extractwood. The few mature 

 ''wolf" trees left from former cuttings should be removed as well as some of 

 the scarlet and black oaks where the stand is too dense. Removal of the 

 latter can be made for ties. The dead and down timber from the laps in the 

 tie and pole cuttings should be removed for extractwood
