The climates of North America according to a new classification. Average snowfall varies from little to none in the South to 2,540 mm (100 in) or more in the mountains of West Virginia, southeastern New York, and southern North Carolina (25). USDA Forest Service, Research Paper NE-195. The pignut hickory is a plant specific to the eastern United States, ranging from eastern Texas through southern states like Mississippi and Alabama, and into central Florida. Since the two ranges seem to overlap, the distributions have been mapped together as a Carya glabra-ovalis complex (11). Natural range of Carya glabra Tree with catkins and galls made by Phylloxera sp. The fruit ripens in September and October, and seeds are dispersed from September through December. Many hickories are used as den trees by several species of squirrels. Hickory is one of several host species of the twig girdler (Oncideres cingulata). Smalley, Glendon W. (1990). On average, Hickory is denser, stiffer, and harder than either White Oak or Hard Maple. These species are rated as intermediate in nitrogen deficiency tolerance and consequently are able to grow with lower levels of nitrogen than are required by "nitrogen- demanding" white ash (Fraxinus americana), yellow-poplar (Liriodendron tulipifera), and American basswood (Tilia americana). This plant has no children Legal Status. The taxonomic position of red hickory is controversial. Washington, DC. Washington, DC. 1970.

It also grows north of the Gulf Coast through Alabama, Mississippi north to Missouri and extreme southeastern Iowa, and the Lower Peninsula of Michigan . Pignut hickory grows in the moist, fertile soils of oak hammocks, bottomland hardwoods, upland slopes, and ridges in association with other oaks and hickories. Price Code: $14.50/$18.50/3'-4'(3 gal) Status: Limited Supply. The pistillate flowers appear in spikes about 6 mm (0.25 in) long on peduncles terminating in shoots of the current year. On Beanfield Mountain in Giles County, Virginia, the former chestnut-oak complex has changed to an oak-hickory association over a period of 50 years. This site is the most xeric habitat on the mountain because of high insolation, 70 percent slopes, and medium- to coarse-textured soils derived from Clinch sandstone. Figure 1. Washington, DC. The catkins usually emerge before the pistillate flowers. Pignut hickory makes up a small percentage of the biomass in low-quality upland hardwood stands that are prime candidates for clearcutting for chips or fuelwood as the first step toward rehabilitation to more productive stands. The species grows in central Florida and northward through North Carolina to southern Massachusetts. The rachis is slender, smooth, and glabrous. area along western Lake Ontario, and southward along the northern shore of Lake Erie and pockets of extreme southwestern Ontario. Hickory has a relatively high heating value and is used extensively as a home heating fuel. The hickories as a group are classed as intermediate in shade tolerance; however, pignut hickory has been classed as intolerant in the Northeast and tolerant in the Southeast. These may coalesce and cause widespread blotching. p. 262-272. Society of American Foresters, Washington, DC. It has pear-shaped fruits with thin husks. These soils are derived from a variety of parent materials-sedimentary and metamorphic rocks, glacial till, and in places varying thickness of loess-which vary in age from Precambrian to Quaternary. This association is dominated by pignut hickory with an importance value of 41.0 (maximum value = 300), northern red oak (36.0), and chestnut oak (25.0). The stem canker (Nectria galligena) produces depressed areas with concentric bark rings that develop on the trunk and branches. Plant Habit or … The range of pignut hickory encompasses 7 orders, 12 suborders, and 22 great groups of soils (24,25). Infested trees and seedlings are not only damaged severely but become ragged and unattractive. Northeastern Forest Experiment Station, Upper Darby, PA. 21 p. Eyre, F. H., ed. Washington, DC. Usually less than half of the seeds are sound (2,3), but 50 to 75 percent of these will germinate. Washington, DC. It is typically found growing in dry, well drained sandy upland ridges and sloped woodlands from southern Ontario, Canada, and in the United States east to … It ranges from Ontario to central Florida and from the east coast to the Mississippi River from southern Michigan to Mississippi. Yields of mixed oak stands (5,7,19) and of hickory stands (2) have been reported. The range of pignut hickory covers nearly all of eastern United States (11). Crude protein, phosphorus, and calcium contents are generally moderate to low. Carya glabra is a tall-growing deciduous tree that can reach a height of 100'. 1). Pignut hickory frequently grows on dry ridgetops and sideslopes throughout its range but it is also common on moist sites, particularly in the mountains and Piedmont. Images are provided in galleries and are available by common name, scientific name, family, ecosystem, and wetland indicator status. Hogs were observed consuming the nuts in colonial America, lending the species its common name. While Smooth hickory is completely restricted to acidic soils, Red Hickory has been found numerous times regenerating on Ordovician Limestone/Shale residuum soils of +6.8PH. The false powderpost beetle (Xylobiops basilaris) attacks recently felled or dying trees, logs, or limbs with bark in the Eastern and Southern States. Each leaf has 5, rarely 7, lance-shaped leaflets that are 4 to 6 inches long by 2 to 3 inches wide. The principal difference is in the husk of the fruit, opening late and only partly, or remaining closed in C. glabra but promptly splitting to the base in C. ovalis. The sessile leaflets usually have glabrous, dark yellowish-green upper surfaces while the underneath surface is paler and glabrous, occasionally pubescent along the midrib. 235 p. Hepting, George H. 1971. The leaves are pinnately compound, alternately arranged, and deciduous. A. Roach. The Index of Plant Diseases in the United States lists 133 fungi and 10 other causes of diseases on Carya species (4,9). The bole is often forked. Pignut hickory is also found in Canada in southern Ontario. Throughout its range, precipitation is rated adequate during all seasons. The hickories grow in mixture with other hardwoods in deep fertile soils. 82 Loblolly Pine-Hardwood Pignut hickory may have potential value for use on some types of disturb-ed sites. Pignut makes up much of the hickory harvested in Kentucky, West Virginia, the Cumberland Mountains of Tennessee, and the hill country of the Ohio Valley. Sweet. On average, Hickory is denser, stiffer, and harder than either White Oak or Hard Maple. Sweet symbol: CAGL8 Leaf: Alternate, pinnately compound, 8 to 12 inches long, with 5 (sometimes 7) leaflets, leaflets are lanceolate and serrate, rachis slender and glabrous, green above and paler below. Dover Publications, New York. The male flowers are dropping catkins yellow-green in color, with 3 hanging from 2 to 3-inch-long stalks. Growth and yield predictions for upland oak stands 10 years after initial thinning. Carya Nutt. Pignut Hickory (#11) Common in the eastern United States and native to Georgia, this tree is considered a “soil improver” because the leaves have a relatively high calcium content. 754 p.

Oak-hickory. The following height growth of pignut hickory seedlings was reported in the Ohio Valley in the open or under light shade, on red clay soil (2): Hickories sprout readily from stumps and roots. Ecology 34:44-54. Growth and yield- Pignut hickory often grows 24 to 27 m (80 to 90 ft) tall and occasionally reaches 37 m (120 ft), with d.b.h. At other times, damage may be confined to the killing of a single tree or to portions of the tops of trees. The nuts are tough and extremely hard to crack. North Central Forest Experiment Station, St. Paul, MN. During drought periods in the Southeast, outbreaks often develop and large tracts of timber are killed. U.S. Department of Agriculture, Agriculture Handbook 436. Crude fiber is very low. The gray bark is deeply furrowed between narrow, interlacing ridges, which are often scaly at the surface.

Carya glabra, commonly called pignut hickory, is a medium to large, deciduous tree with a straight trunk and rounded crown that typically grows 50-80’ (less frequently to 100’) tall. Stump sprouting is not as prolific as in other deciduous trees species but the sprouts that are produced are vigorous and grow fairly rapidly in height. A., and S. F. Gingrich. 79 Virginia Pine In much of the area covered by mixed oak forests, shade-tolerant hardwoods (including the hickories) are climax, and the trend of succession toward this climax is very strong. Even-aged silviculture for upland central hardwoods. Its relatives include the pecan (Carya illinoinensis) and black walnut (Juglans nigra), two of the most important native nut trees in North America. It is thick-walled, unridged, and encased in a thin husk that only splits half way open. Carya glabra (pignut hickory) is a tree in the Juglandaceae or Walnut family.

"Carya glabra". The best development of this species is in the lower Ohio River Basin. The deciduous, 8- to 12-inch long leaves create a coarse, oval canopy, and the strong but irregularly spaced branches resist breakage in storms, making it useful as a shade tree. The hickory is particularly beautiful when winter buds open in late spring; the bud scales fold back, petal-like, as new foliage emerges. Campbell, W. A., and A. F. Verrall. 80 Loblolly Pine-Shortleaf Pine Other common names include sweet pignut, smoothbark hickory, swamp hickory, and broom hickory.
