Acorn production in northern red oak stands in northwestern Pennsylvania / L.R. Auchmoody, H. Clay Smith, Russell S. : L. R. Auchmoody. of red oak or production of acorns. Soil textures range from sandy loam to silty clay loam; the effective soil depth ranges from about 24 to 30 inches. Humus types are duff mull. Each of the even-aged stands originated after clearcutting and is dominated by northern red oak in the overstory. SiteCited by: acorn damage, magnitude of acorn crops per tree, and time of acorn fall, within a stand of mature northern red oak, Quercus rubra. Materials and Methods In the fall of , we received a sample of northern red oak acorns from the Watauga Seedling Seed Orchard in the U.S.D.A. Forest Service Cherokee National Forest near Mountain City, TN.
The study was conducted in a 40 ha even-aged stand of the white pine-northern red oak-red maple forest cover type (type 20; Eyre, ) in central Massachusetts. Healy () reported the short-term effects of thinning on acorn production in a sample of dominant and co-dominant oaks, half of which grew in a 15 ha part of the stand that had. For this reason, red oak group acorns are a more available food source through the winter than white oak group acorns. Acorn Production Variability. Overall, acorn production is highly variable among trees even in good seed years. Some trees are always poor producers while others are always good producers. Oaks in the red oak family typically have a heavier acorn crops every years. Red oak acorns take two years to develop. Environmental conditions, such as heavy spring rains, flooding, drought, and unusually high/low temperatures, can cause poor acorn pollination, acorn crop abortion, and complete acorn crop failures. acorn production in trees of the red oak group is not as closely synced, and acorn production by individual trees within a stand will often vary drastically. Also, only a small percentage of trees in a stand of either oak group is capable of heavy acorn production in any given year. Studies have.
Using the fourth quarter report for northwestern Pennsylvania provided in this publication (Table 8 on page 17) we see that red oak is selling for $ per thousand board feet (MBF), white oak for $ per thousand, red maple for $ per thousand, and yellow-poplar for $ per thousand, and we use the miscellaneous hardwood price for. Northern Red Oak Northern Red Oak: Leaves: Alternate, simple, 4”-9” long, to 6” wide, with bristle-tipped lobes, sinuses between lobes extend half-way to the mid rib. Smooth, dull green above, paler with small tufts of reddish-brown hair in vein-axils (i.e., where the side veins join the mid-rib) beneath. Twigs: Greenish-brown to. the red oak group (containing tannic acid). Another difference between the groups is that acorns from the white oak group mature in one year, while acorns from the red oak group mature two years after the flowers are pollinated. As a result, red oak acorn production can be affected by conditions that occurred over two years of weather events. Quercus rubra L.. Northern Red Oak. Fagaceae Beech family. Ivan L. Sander. Northern red oak (Quercus rubra), also known as common red oak, eastern red oak, mountain red oak, and gray oak, is widespread in the East and grows on a variety of soils and topography, often forming pure te to fast growing, this tree is one of the more important lumber species of red oak .
