List of inventoried conifers in the United States

Silvics of North America (1991), a forest inventory compiled and published by the United States Forest Service, includes many conifers. It superseded Silvics of Forest Trees of the United States (1965), which was the first extensive American tree inventory. A variety of statistics on all of these trees are maintained by the National Plant Data Team of the US Department of Agriculture.

All of the conifers in the inventory except the larches and some bald cypresses are evergreens. Apart from two species in the yew family, all are in either the pine family (including firs, larches, spruces, pines, Douglas firs and hemlocks) or the cypress family (including junipers, redwoods, giant sequoias, bald cypresses and four genera of cedars).

Softwood from North American conifers has a variety of commercial uses. The sturdier timber is milled for plywood, wood veneer and construction framing, including structural support beams and studs. Logs can be fashioned into posts, poles and railroad ties. Less sturdy timber is often ground and processed into pulpwood, principally for papermaking. Resins from sap yield wood tar, turpentine or other terpenes. Some resins and other tree products contain dangerous toxins (not generally listed below).
