1 Lumber trade practice specifies white ash and brown ash. The former is cut from the white-ash tree 
and the latter from the blaclc-ash tree. White ash {Fraxinus aviericana) is cut principally in the Central 
States. Green ash (F. lanceolata) is cut principally in Southern States. Black ash (F. nigra) is cut in 
the Lake States and northeastern folates. Reel ash (F. pevnsylvanica) is cut in limited quantity in the 
Eastern States. Oregon ash (F. oregrma) is cut in the Pacific Northwest.
