In 2002, in the United States, 21,904 Christmas tree farms covering 447,000 acres (1,809 km2) of cropland accounted for the 20.8 million Christmas trees cut. Of those farms, 686 harvested 100 acres (0.4 km2) or more, which accounted for over 196,000 acres (793 km2) of the total area of trees harvested. That same year, there were only three U.S. Christmas tree farms with more than 10,000 acres (40 km2) of cropland in production. The total U.S. crop in 2004 was valued at $506 million with $143 million attributed to the nation’s leading producer in 2004, Oregon. Oregon was followed in production numbers by North Carolina, Washington, and Michigan.
