Effects of alternative silvicultural practices on oak regeneration in the southern Appalachians
The regeneration in oak-dominated stands following five silvicultural treatments was examined on four sites in the mountains of Virginia and West Virginia. Treatments included: silvicultural clearcut, leave-tree, commercial clearcut, shelterwood, and group selection. The effects of harvesting were …

Oak regeneration after clearcutting on steep slopes in the ridge and valley province of southwest Virginia
The development of oak stems of advance regeneration and stump sprout origin was studied during a two-year period following clearcutting and whole-tree removal in eight midslope stands in the Ridge and Valley Province of southwestern Virginia. Oak regeneration was also characterized in several …

Overstory density and its effect on oak regeneration abundance and oak understory height growth in the Missouri Ozark Highlands
This study examined how overstory density affects regeneration abundance and understory height growth in the Missouri Ozark Highlands. Data were collected on three different treatment types, no harvest management, uneven-aged management, and even-aged management. The probability of obtaining …

Long-Term Study of Prescribed Fire Effects on Stand Dynamics and Oak Regeneration Potentials in Degraded Upland Oak-Hickory Stands in Northwestern Arkansas
<p>Upland oak-hickory forests in the Ozark Mountains of northwestern Arkansas and south central Missouri were impacted by oak decline during the early 2000s. This decline event was caused by predisposing (e.g., mature, dense stand conditions), inciting (i.e., drought), and contributing (e.g., red …

Silvicultural Methods for Improving Hardwood Management on Non-Industrial Private Forest land in Virginia
… increases in volume after three years. When oaks are harvested or a major disturbance occurs, the number of oaks that regenerates is less than there were previously (Smith 1992). Therefore, oak regeneration is a problem and methods are needed to facilitate oak regeneration (Smith 1992). One …

Effects of gypsy moth defoliation on acorn production and viability, litterfall, and litter layer depth and biomass in north-central Virginia and western Maryland
… on acorn production (the seed source for oak regeneration), and the forest floor regeneration environment were investigated. Parameters measured included: acorn quantity, weight, development, and viability; litterfall; and forest floor depth and biomass. Nineteen plots in north-central …

Floristic dynamics of Appalachian pine-oak forests over a prescribed fire chronosequence
… among the sapling and shrub strata. Pine and oak regeneration abundance was not affected by fire but shade tolerant tree seedlings decreased, and shade intolerant seedlings increased in importance as a result. Percent cover and richness of herbaceous species increased, partly due to the …

Fungi associated with northern red oak (Quercus rubra ) acorns
Poor regeneration of northern red oak is widespread in the central hardwood region. A two-part study was conducted to determine what fungi are associated with and cause cotyledon discoloration of northern red oak acorns. The field study determined that simulated small mammal notching, surface …

Forest Composition, Regeneration, and Tree Quality in the Southern Appalachian Mountains of Virginia: Selective Cutting vs. Shelterwood
… (SC) and the first shelterwood (SW) cut in oak (Quercus)-dominated forests of western Virginia. The specific attributes compared were: (1) tree species composition; (2) seedling, sapling, and overstory tree density; (3) overstory tree quality and size; (4) sapling crown class; and (5) canopy …

Impacts of oak-focused silvicultural treatments on the regeneration layer nine years post-treatment in the southern Appalachian Mountains of North Carolina
Oaks (Quercus spp.) are an important part of the forested landscape in the eastern United States. Although oak is increasing in standing volume, an oak regeneration bottleneck has occurred throughout its range in recent decades. Subsequently, as oak overstory is being harvested, rarely is oak …

Effects of Tornado Damage, Prescribed Fire, and Salvage Logging on Oak (Quercus Spp.) Saplings in Upland Oak Forests in Northern Mississippi
… folloby long periods of fire suppression, oak dominated forests, woodlands, and savannahs are being replaced by an unprecedented forest ecosystem. In Mississippi, these new forest systems are dominated in the mid- and understory by mesophytic species such as red maple (Acer rubrum L.) and …

Savanna Restoration Through Prescribed Fire: Demographic and Physiological Responses of Oak and Hickory Seedlings and Saplings to a Changing Light Environment
… tool for restoring and maintaining degraded oak savannas in the Midwest. Long-term success of restoration and maintenance ultimately depends upon new individuals entering the canopy. However, little is known about seedling and sapling response to this periodic disturbance. This study …

Effects of understory vegetation manipulation on hardwood regeneration recruitment and growth in southern Appalachian forests
The successful regeneration of mature oak (<i>Quercus</i> spp.) forests is thought to be dependent on the presence of oak advance regeneration. However, the advance regeneration must be of sufficient size and density for oak to be competitive and become a dominant species after harvest. The …

The Fungal Connection: Characterizing the Ectomycorrhizal Community and Belowground Response to Restoration Treatments in Northern Mississippi.
… plot also had the greatest canopy openness and oak regeneration, suggesting that this greater spatial autocorrelation could be related to oak seedling facilitation. The restoration treatments did not have a strong impact on fungal community structure except in the Tallahatchie plots, where there …

Perspectives on oak savanna restoration in Minnesota: a dendroecological approach
… disturbances have diminished the extent of oak savannas throughout the Midwest and altered what few remnants remain. Although oak savanna restoration is of great interest to the public and reserve managers, scientists do not fully understand the intricate dynamics of the ecotone, leaving …

Negative Effects Of ComMycorrhizal Networks And Roots On Upland Oak Seedlings In Open-Canopy Woodlands And Closed-Canopy Forests
After extensive logging and fire suppression many oak dominated woodlands or forests are in danger of being replaced by a mix of non-pyrogenic and shade tolerant tree species that benefit from fire suppression. Successful advanced regeneration by oaks in forests and woodlands depends both on the …
