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 It superseded Silvics of Forest Trees of the United States (1965), which was the first extensive American tree inventory.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 used for plywood, wood veneer and construction framing, including structural support beams and studs. Milled 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.

These are often divided up into:
 * A column of five states just west of the river: AR IA LA MN MO (including the parts of LA and MN that are east of the river)
 * A column of six states that overlap the Great Plains: KS ND NE OK SD TX
 * The continental Western United States: AK AZ CA CO ID MT NM NV OR UT WA WY
 * Another useful division is the South Central states: AR LA OK TX
