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. Rernoval 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
