|Florida scrub, and dry sands where planted outside of its native range, for instance widely planted in pulp plantations in FL and s. GA, experimentally planted as far north as NC (and persisting and naturalizing).
|FL Panhandle, S. AL, south to s. FL; planted and naturalized further north in GA, SC, and NC Coastal Plain and further west in s. MS.
|Shortleaf Pine, Rosemary Pine, Yellow Pine
|Dry to dry-mesic upland forests and woodlands, rocky ridges and slopes, glades, bluffs, Coastal Plain sandhills, old fields, riparian forests, generally in rather xeric sites and on acid soils, but also occurring in mesic to even wet sites and on mafic or subcalcareous rocks.
|Widespread in se. North America, north to s. NY, NJ, s. PA, s. OH, s. IL, s. MO, and e. OK, perhaps reaching its greatest importance in dry, sandstone landscapes, such as the Cumberland Plateau of WV, KY, TN, and AL, and the Ozarks and Ouachitas of AR, MO, and OK.
|Native in wet pine flatwoods and maritime forests, also extensively planted (over a broader distribution than the natural one, as in GA, SC, NC, w. LA, e. TX) in silvicultural plantations on a wide variety of soils, many of them unsuitable for its successful growth.
|P. elliottii ranges natively from e. SC south to c. peninsular FL, west to e. LA. P. elliottii has been extensively planted throughout the Coastal Plain of Georgia, North Carolina, and South Carolina, where it now occupies tens of thousands of hectares.
|Spruce Pine, Walter's Pine, Cedar Pine
|Bottomland forests, rich, moist soils, also upland in calcareous areas, such as calcareous bluffs.
|SC south to n. FL and west to se. LA
|Longleaf Pine, Southern Pine
|Formerly throughout the Coastal Plain, Sandhills, and lower Piedmont, on a wide variety of soils (sandy, loamy, clayey, or peaty), from very dry to very wet conditions, in pine savannas, pine woodlands, and pine forests affected by relatively frequent natural (lightning caused) fires (likely augmented by native Americans), now reduced to less than a tenth of its former abundance by a variety of forces, including turpentining, timbering, free-range hogs, fire suppression, and ‘site conversion’ by foresters to other trees, now extremely rare in VA and north of the Neuse River in NC, still occurring in some abundance in the outer Coastal Plain from Carteret County, NC south into GA, in the Bladen Lakes area of Bladen and Cumberland counties, and in the Fall-Line Sandhills of Harnett, Hoke, Scotland, Richmond, Moore, Anson, and Montgomery counties, NC and south into GA.
|A Southeastern Coastal Plain endemic: se. VA south to FL and west to se. TX; it extends slightly into the Piedmont in most states where it occurs, and further into the Piedmont and low mountains in GA and AL.
|Maritime Pine, Cluster Pine
|Planted and naturalized on barrier islands.
|Native of Mediterranean Europe. P. pinaster is reported by Brown (1959) to be "introduced from Mediterranean region and planted on sand-flats in vicinity of Corolla, Currituck Banks, Bodie and Hatteras Island 1936-1940…". Now producing seeds and becoming naturalized near Cape Hatteras Lighthouse.
|Table Mountain Pine, Bur Pine, Prickly Pine, Hickory Pine
|Dry ridges, cliffs, shale barrens, usually requiring fire for its reproduction, occurring at least up to 1550 m.
|A Central and Southern Appalachian endemic: n. NJ, through se. PA, w. MD, WV, w. VA, w. NC, and e. TN to nw. SC and ne. GA. Occasionally planted outside its natural distribution, as in NY.
|High elevation forests, in pine plantations, and persisting after silvicultural planting.
|This species is native as far south as WV (Pendleton and Hardy counties) and PA (Luzerne, Wyoming, Tioga, and Centre counties).
|Pitch Pine, Black Pine
|Southward primarily on dry ridges, more or less requiring fire for its reproduction, less commonly in peat soils of mountain bogs (and then often at elevations of 800-1000 m), northward (as in NJ) in acidic sandy and peaty soils near sea level, and also scattered through a variety of forest types. It is abundant near sea level in the Pine Barrens of NJ, but in NC is limited to the mountains and upper Piedmont; it is replaced in Coastal Plain fire-maintained wetland communities by the related Pinus serotina.
|S. Canada and s. ME south to n. GA.
|Pocosin Pine, Pond Pine, Marsh Pine, Black Pine
|Peaty soils of pocosins, swamps of small blackwater streams, sometimes a component of very wet pine savannas over an herbaceous groundlayer, but usually associated with dense pocosin shrubs.
|A Southeastern Coastal Plain endemic: s. NJ south to n. FL and se. AL, restricted to the Coastal Plain.
|Eastern White Pine
|Moist to dry forests, bottomlands, dry, rocky ridges in humid gorges.
|Widespread in ne. North America, south to VA, w. and (rarely) c. NC, nw. SC, n. GA, e. TN, KY, IN, n. IL, e. IA, and MN. In NC, a notable relict and disjunct stand of P. strobus occurs on bluffs of the Deep River in the eastern Piedmont of Chatham County; in VA P. strobus is widely but irregularly distributed in the lower Piedmont.
|Pinus sylvestris var. sylvestris
|Cultivated and sometimes escaped or long persistent in settings where not obviously planted.
|Native of Europe. Introduced and at least weakly naturalized south to MD (Kartesz 1999) and e. WV (Morton et al. 2004).
|Loblolly Pine, Old Field Pine, Yellow Pine
|Dry to dry-mesic upland forests and woodlands, riparian forests, maritime forests, sandy rises in bottomland forests, pine flatwoods, roadsides, pine plantations, disturbed areas, especially in acid soil, much more abundant and widespread than formerly, and occurring farther inland than as a native.
|Native from s. NJ, DE, and e. MD south to n. peninsular FL, west to e. TX and se. OK, primarily on the Coastal Plain, but inland to s. TN; this distribution now expanded by forestry plantation northward.
|Japanese Black Pine
|Planted and persisting, sometimes appearing native, on barrier islands.
|Native of Japan.
|Virginia Pine, Scrub Pine, Jersey Pine, Possum Pine, Spruce Pine
|Dry forests and woodlands, especially on slopes and ridges, also common in certain areas as a weedy successional tree on nearly any kind of site, such as rocky, sandy, or clayey successional old fields or blowdowns.
|Primarily a Central and Southern Appalachian endemic: s. NY, NJ, and PA, south through VA, WV, s. OH, s. IL, KY, TN, and NC to nw. SC, n. GA, n. AL, and ne. MS.
|Reported as possibly naturalized in WV (Harmon, Ford-Werntz, & Grafton 2006).
|Native of Europe.
|South Florida Slash Pine
|Restricted to c. and s. peninsular FL. Falsely reported by Small (1933) for GA.
|Italian Stone Pine
|A single report from Graham County, NC on EDDMapS; of uncertain reliability and rejected unless corroborated.
