Total U.S. forestland has remained stable at around 751 million acres over the last 100 years even though U.S. population tripled during the same period.  It is important to note that the 751 million acres do not include forest cover in and around urban areas. Although some urban forests when viewed by remote sensing, meet the criteria of forest (minimum tree cover and area) on-the-ground inspections indicate they are used primarily for non-forest purposes. However, trees in urban forests continue to sequester carbon, reduce energy use, and increase human health and well-being.
