PORTLAND - Hazelnut operations have declined by almost 5 percent, while hazelnut acres have declined by about 3% since 2001, according to the 2004-2005 Hazelnut Tree Survey. The declines in acreage have been mainly attributed to damage caused by the Eastern Filbert Blight.
The 2004-2005 Hazelnut Tree Survey reported 28,400 hazelnut acres, while the same survey conducted in the years 2000-2001 reported 29,140 acres, indicating a decrease of 740 acres in the last four years. Hazelnut operations were reported as numbering 648 in the 2004-2005 survey and 681 in 2000-2001, indicating a decrease of 33 operations.
Ranked by county tree inventory, Oregon's leading hazelnut producing counties also experienced a decline and include Yamhill with a decrease of 1 percent, Marion with a decrease of 12.7 percent, Clackamas with a decrease of 18 percent and Washington with a decrease of about 5 percent. Washington state figures were discontinued in 2001.
