Abstract The performance of planted northern red oak (Quercus rubra L.), black walnut (Juglans nigra L.), and green ash (Fraxinus pennsylvanica Marsh.), with and without tree shelters, was evaluated 10 yr after planting. Northern red oak was planted in three harvested forest openings, and black walnut and green ash were planted in a cultivated field. Survival of northern red oak with tree shelters was significantly (P < 0.05) higher than northern red oak without shelters only for year 3. Survival differences between tree shelter treatments for black walnut and green ash were not significant. However, overall survival of green ash declined rapidly after year 5. Trees began to exit the 120-cm-tall shelters after 2 yr, but not in large numbers until the fourth year. Sheltered oaks were significantly taller than unsheltered oaks at year 10, and sheltered oaks had more height growth than unsheltered oaks at year 5, but not at year 10. Except for year 1, neither height nor height growth for black walnut was significantly different between tree shelter treatments. Green ash was taller and had more height growth with shelters than without shelters in year 1, but had more height growth without shelters than with shelters in year 5. Diameter growth at breast height did not differ between treatments for any of the three species. The greater height of sheltered northern red oaks compared to unsheltered northern red oaks could increase the opportunity of sheltered oaks to achieve dominant and codominant positions in the developing stands.

Abstract Survival and height of four hardwood species—black walnut (Juglans nigra L.), northern red oak (Quercus rubra L.), white oak (Q. alba L.), and black oak (Q. velutina Lam.)—were evaluated 4 yr after the trees were outplanted in a recently harvested hardwood site. The study evaluated the influence of numbers of first-order lateral roots (FOLR); preplanting-root treatments (RT) that included both separate and combination treatments of a biostimulant, Roots®, a moisture loss retardant, SuperSorb-F® (SS), and a water control; and tree shelters (TS) on seedling performance.Except for black walnut, 4 yr survival was significantly (P ≤ 0.05) higher with tree shelters than without them. However, survival was not affected by FOLR or RT. The number of FOLR significantly affected the 4 yr height growth of northern red oak and black oak, but they did not affect the height growth of black walnut and white oak. Four-year height growth for black walnut and northern red oak was greater for unsheltered trees than for sheltered trees; the reverse was true for white oak and black oak. First-order lateral roots, root collar diameter (RCD), and TS were significantly correlated with first-year height and/or 4 yr height growth. Root treatments did not affect height growth. The overall good survival and limited treatment effect indicate that the number of FOLR was of limited importance on this site for these tree species. However, treatment effects may have been different on a more stressful site. North. J. Appl. For. 17(2):45-50.

Abstract Seasonal effects on transplant establishment of balled-and-burlapped (B&B) shade trees are not well documented. Early post-transplant root growth and aboveground growth over a 3-year period were therefore determined for November-and March-transplanted northern red oak (Quercus rubra L.) and willow oak (Q. phellos L.). Survival of red oak was 100% for both treatments. Survival of November-and March-transplanted willow oak was 67% and 83%, respectively. No new root growth was observed outside or within the root balls of either species upon excavation in January. New root growth was evident when trees of both species were excavated in April, indicating that root system regeneration of November-transplanted trees occurs in late winter and/or early spring, not late fall and/or early winter. November-transplanted red oak, but not willow oak, grew more roots by spring bud break than March-transplanted trees. However, little difference in height growth and trunk expansion was evident between the November-and March-transplanted red oaks throughout the 3 years following transplant. While height growth of willow oak was nearly identical between treatments after 3 years, November transplants exhibited greater trunk diameter increase for all 3 years. Overall, season of transplant had little effect on height and trunk diameter increase of red oak, even though November-transplanted trees grew more roots prior to the first bud break following transplant. Among the willow oaks that survived, season of transplant had little effect on new root growth and height growth, but November transplanting resulted in greater trunk expansion. However, when the mortality rate of November-transplanted willow oak is taken into consideration, March may be a better time to transplant willow oak in climates similar to southwest Virginia.

Abstract Planting has been considered to be one solution to the problem of inadequate natural oak regeneration following harvesting in the Central Hardwood Region. Two types of tree shelters were used in two separate 3-year studies to determine their effects on the growth and survival of northern red oak seedlings planted in recently harvested forest openings, and to characterize shelter influence on microenvironmental factors. Sheltered seedlings planted in both trials exhibited significantly greater 3-year height growth as compared to the controls. There were no significant differences in survival rates. Relative humidity and carbon dioxide concentrations were increased significantly inside both types of shelters, while there were no differences between shelter exterior and interior daytime temperatures. Interior light intensities differed for the two shelter types and varied according to vertical location within shelters. Recommendations are given for using tree shelters as a possible means for improving oak planting success in recently harvested forest openings. North. J. Appl. For. 9(2):58-63.

Abstract Survival, height, and diameter growth of seedlings were evaluated for three years after planting using five types of tree shelters and seven species: green ash (Fraxinus pennylvanica), northern red oak (Quercus rubra L.), pin oak (Q. palustris), American sycamore (Platanus occidentalis), black walnut (Juglans nigra L.), flowering dogwood (Cornus florida), and eastern white pine (Pinus strobus). Differences in shelter environments were measured, including: light transmission measured as percent photosynthetic photon flux, ratio of red:far red (r:f-r) light from the red and far-red wavelengths, and air temperature inside the tubes. The differences seen in seedling survival were not significant (p < 0.05) for the presence or type of tree tube, with an average survival of 96% for all but two species. For most species, seedlings grown in high light-transmitting tubes with proportional r:f-r ratio light showed superior height growth (e.g., Miracle Tube, Tree-Pro, and Protex). Diameter growth generally decreased in shelters. Sycamore showed no significant benefit from the use of tubes. The lowest diameter increments were seen using Tubex brown and Mesh Guard shelters, which had low light transmission with high r:f-r ratio and mechanical damage, respectively. Light transmission in translucent tree tubes was within the ranges found in open canopy forest, but the proportion of growth-promoting far-red wavelength was generally lower. In tubes with higher light transmission, r:f-r ratio is closer to natural ranges for that light level. For tubes with lower light transmissivity, this information suggests that seedling height growth might be improved if red wavelengths were blocked more strongly.North. J. appl. For. North. J. Appl.

Abstract The use of tree shelters with naturally established red oak seedlings was studied in southern New England mixed-hardwood stands where deer browsing limited regeneration height growth. Seedlings of three size classes (basal diameters of 5 mm, 8 mm, and 15 mm) were cut off just above ground level during the dormant season to induce sprouting. Plastic tree shelters were placed over one group in each size class; another group was left without shelters but was protected from deer browsing by fencing. In the first growing season, seedling sprouts inside shelters in the two larger size classes had double the height growth (with some terminals growing out of the 150-cm tall shelters) but less diameter growth, compared to sprouts outside shelters. The height difference was maintained but not increased over the next 2 growing seasons. Height growth for sprouts from the smaller size class was not increased by shelters. The use of tree shelters with large diameter seedlings stunted by browsing may have potential for ensuring successful red oak regeneration without the costs of planting. North. J. Appl. For. 9(4):141-145.

Abstract A major concern in the management of northern red oak (Quercus rubra L.) is the difficulty in regenerating stands that have dense understories of shade tolerant species. A replicated study in southern Iowa indicated that over a 5 yr period, tree shelters have a major impact on establishment of underplanted, 1-0, northern red oak bareroot stock. Sheltered seedlings had increased height growth during the first 3 growing seasons. But during the next 2 growing seasons, annual height growth of sheltered seedlings declined to a level of annual height growth similar to that of nonsheltered seedlings. After 5 growing seasons, sheltered seedlings were approximately 30 cm taller than nonsheltered seedlings. Sheltered and nonsheltered seedlings were one-third to two-thirds the height of the shelters. At the end of the fifth growing season, total mortality for sheltered seedlings was 40 and 55%, whereas for nonsheltered seedlings, mortality was 26 and 28% at the McNay and Stephens sites, respectively. Tree shelters may be a viable alternative in open areas (e.g., clearcuts or plantations), but in this study, tree shelters reduced both growth and survival when used to protect underplanted, 1-0, red oak seedlings.

Mortality and growth rates of trees in various crown classes and size classes were analyzed from 40-year permanent plot records of slope and ravine forest dominated by chestnut oak (Quercusprinus L.) and northern red oak (Quercusrubra L.). Average 5-year mortality rates for suppressed trees ≥2.5 cm dbh of chestnut oak and red oak in the slope forest were 26 and 45%, respectively. None of the suppressed red oaks survived the 40-year period, compared with 14% of the chestnut oaks and 33% of the red maples (Acerrubrum L.). Mortality of oak trees in the intermediate crown class was less than half that of suppressed trees, but still much higher than that of maples and birches on the tracts. Survival was reasonably high for oaks as long as the top of the crown was receiving direct sunlight, but the expected 40-year survival rate of red oaks in such a position is only 20%, with an average growth rate of 1.0 mm in diameter per year. Curves and equations expressing average mortality and growth rates at various levels of competition are presented for each species.

Previous research by the authors found simulated acetochlor (with atrazine) and s-metolachlor drift to white oak at the leaf unfolding stage caused loss of interveinal tissues (leaf tatters). Reports of leaf tatters in the landscape and nursery settings are more common on white oak (Quercus alba L.) than on northern red oak (Quercus rubra L.). Our objectives were to determine if white and northern red oak differed in susceptibility to chloroacetanilide herbicides, if injury varied between chloroacetanilide herbicides, and if adding atrazine increased leaf injury. Two-year-old seedlings at the leaf unfolding stage were treated with acetochlor, s-metolachlor, and dimethenamid-P alone or combined with atrazine at 1%, 10%, and 25% of the standard field use rate. Within 6 days, all chloroacetanilides at 10% and 25% field use rates, alone or combined with atrazine, caused leaf tatter injury in both species. Acetochlor, s-metolachlor, and dimethenamid-P caused a similar type of leaf injury. Atrazine did not cause loss of leaf tissues or increase injury from chloroacetanilides. At 1% field use rate, only acetochlor, acetochlor + atrazine, and dimethenamid-P caused leaf injury to northern red oaks. The white oaks were not injured by all of the chloroacetanilide treatments at 1% field use rate. The northern red oaks were slightly more susceptible to chloroacetanilides compared with the white oaks. A second study found acetochlor only injured northern red oak when applied at the leaf unfolding stage and only at 25% of field use rate. Acetochlor at 1% field use rate did not injure red oak. Research is needed to explain the greater frequency of leaf tatters on white oaks than on northern red oaks in the landscape and to develop strategies to avoid tree injury.

Abstract Two procedures were evaluated for assessing tree susceptibility to Anoplophora glabripennis. In the first procedure, adult beetles were caged with a section of sugar maple, northern red oak, white oak, honeylocust, eastern cottonwood, sycamore or tulip poplar wood. Results showed that females laid viable eggs on sugar maple, red oak, white oak and honeylocust. Oviposition did not occur on cottonwood, sycamore, or tulip poplar. Eighty-seven percent of the first instar larvae survived in white oak, followed by sugar maple (82%), honeylocust (50%), and red oak (39%). In the second procedure, first instar larvae were manually inserted into potted sugar maple, green ash, and red oak trees and allowed to feed for 60 or 90 days. Significantly more larvae survived for 90 days within the red oak (67%) compared to green ash (17%). Larvae recovered from red oak weighed significantly more than larvae from sugar maple or green ash. Larval survival was positively related to height of insertion. These results indicate: 1) controlled laboratory and greenhouse-based procedures can be used to assess tree suitability to A. glabripennis and 2) A. glabripennis will oviposit and larvae can develop in northern red oak for up to 90 days, suggesting that this species may be a potential host.

Abstract Sulfometuron (Oust®) and glyphosate (Roundup®) were applied separately and as tank mixes to plots direct seeded with northern red oak, white ash, and white pine. Treatments included applications of glyphosate, sulfometuron (low and high rate), sulfometuron (low and high rate) + glyphosate, and an untreated control. Results after 2 years showed no effect of sulfometuron at either rate on the emergence of northern red oak and white ash. Emergence of white pine was reduced by both rates of sulfometuron alone or in combination with glyphosate. Sulfometuron at the higher rate alone or in combination with glyphosate reduced the height growth of northern red oak and white ash, and increased first-year mortality of northern red oak. Height growth and first-year survival of white pine was not affected by either rate of sulfometuron. Glyphosate alone or in combination with sulfometuron at the lower rate had no adverse effect on the emergence or seedling growth of northern red oak, white ash, or white pine. North. J. Appl. For. 8(1):9-11
