Major tree nuts

According to the U.S. Department of Agriculture, the total U.S. value of utilized nut production is around $1.91 billion, an increase of about 26 percent from 2001. Major varieties grown in the U.S. are almonds, walnuts, pecans, pistachio, hazelnuts, macadamia nuts and a few specialty products like pine nuts and hickory nuts.

We're talking only of tree nuts here, which excludes peanuts.

Many nut growers are members of cooperatives, which buy, process and market their members' nuts. Diamond Walnut, the biggest grower of walnuts, was formed in 1912, and now sells more walnuts than any other groups. It has 1,900 grower-owners, mostly on relatively small family farms. The co-op has expanded beyond walnuts, adding hazelnuts, pinenuts, almonds, pecans, and macadamia nuts, and is currently the leading walnut supplier to 80 percent of the nation's ingredient buyers.

Will current nut orchards be able to keep up with demand? According to the Tree Nut Assn., sales look pretty strong, but more trees are coming on line, and some of the new varieties bear earlier and are more prolific.
