During the period 1960-1973 total production of domestic tree nuts nearly doubled and the value of production more than tripled. Pecans, walnuts, and almonds each comprise about 30 percent of the total production; filberts and Macadamia nuts account for the remainder. Marketing agencies have declined in number but increased in size during the past 13 years. Marketing channels and outlets have remained about the same, except that prepared dry cereals are a new outlet for almonds and pecans, and gift packs have become more important for all tree nuts.
