List of inventoried conifers in the United States
Silvics of North America (1991) is a forest inventory published by the U.S. Forest Service. It updates the earlier 1965 edition and, like the whole set, is supported by statistics from the National Plant Data Team of the U.S. Department of Agriculture.
Key facts about inventoried conifers
- Most conifers are evergreens, but a few are not, such as larches and some bald cypresses.
- They are mainly in two families: the pine family (which includes pines, firs, larches, spruces, Douglas firs, and hemlocks) and the cypress family (which includes junipers, redwoods, giant sequoias, bald cypress, and four genera of cedars). A couple of species in the yew family are also noted.
- Uses of North American conifer wood are broad: strong timber is milled into plywood, wood veneer, and construction framing (beams and studs); logs can become posts, poles, and railroad ties; lighter timber is often processed into pulpwood for papermaking; resins from the sap yield products like wood tar and turpentine. Some resins and related products can contain toxins.
Geography and distribution (in brief)
- Conifers are found across the continental United States and Alaska. Hawaii has no conifers listed in the 1991 inventory.
- They are most common in the western states, especially the Pacific Northwest and the Rocky Mountains, with extensive stands in Alaska and in parts of the western and southwestern U.S.
- They are present in many eastern states as well, though distribution and species vary by region.
- The inventory provides detailed, state-by-state information on species, sizes, growth rates, and uses, reflecting how conifers occur across different landscapes and climates.
