The first Christmas tree farm in the United States is believed to have begun in 1901 when 25,000 Norway Spruce trees were planted by W. V. McGalliard in Mercer County, near Trenton, New Jersey. The trees were sold seven years later for US$1.00 each. Despite the early pioneers of the industry, by the late 1940s 90 percent of all natural Christmas trees sold in the United States were still harvested from forests. The most popular species during that era, Balsam Fir, Douglas-fir, Black Spruce and White Spruce, were all readily available from forests.
