In a study of hardwood regeneration, experimental plots were treated to produce residual densities of 40, 60, 80, and square feet of basal area per acre w 45, and 60 percent sawtimber. After 9 years, numbers of stems and percent stocking were estimated for each species and they were rated for reproductive potential under different residual densities.

Most regeneration of hardwood forests occurs naturally--that is, without planting trees--but many factors can affect forest regeneration. To regenerate naturally, the current forest must produce seedlings, stump sprouts, and root suckers that will become the next forest following a.
would allow the stand to be carried at satisfactory stocking and must be regenerated. Because of the past ﬁhigh gradingﬂ cutting practices or wildfires, many upland hardwood stands are under-stocked with desirable trees, contain many ﬁcullﬂ trees and need regeneration.

While the same regenerating stand, containing to competitive saplings of a high valued species provides the basis for reaping significant benefits in the future. The goal for hardwood regeneration is to ensure that 10 to12 years after the regeneration harvest the stand contains adequate numbers of saplings, typically between and In tolerant hardwood forests of eastern North America, multiple-aged silvicultural systems rely on advanced regeneration to restock the forests.
Evaluation of the long-term influence of advanced regeneration on the mature stand is critical for improving management by: 2. A second possible explanation for the high regeneration densities could be related to the residual density of overstory seed-producing trees.

Stand will undergo an overstory removal on roughly 60% of the stand to release the outstanding regeneration in areas with a slowly failing overstory.
Areas that still have a quality overstory will continue to be managed all aged using single tree selection. Sale establishment will occur in High grading is the removal of the most commercially valuable trees from the stand, often leaving a residual stand composed of trees of poor quality, poor species composition, or both.
A high-graded stand often has little or no future economic value with regard to timber. Product : Robert Bardon. However, subsequent browsing damage combined with the negative influence of the residual overstory cover can limit the longer-term benefit of understory herbicide treatments.
Subsequent removal of the overstory and browsing-control measures may be needed to promote sugar maple regeneration over beech in similar northern hardwood by: 4. Wood exchanges moisture with air; the amount and direction of the exchange (gain or loss) depend on the relative humid-ity and temperature of the air and the current amount of water in the wood.

Description Influence of residual stand density on regeneration of northern hardwoods FB2
Traditionally, legacy-tree retention has been primarily applied as a modification of even-aged regeneration methods (e.g., clearcutting with reserves, irregular shelterwoods); however, recent work in northern hardwood systems is highlighting the value of applying this approach within group selection openings to meet biodiversity conservation.
northern hardwood forests, we conducted a regeneration survey of twenty-nine (29) small clearcuts in central New Hampshire and western Maine. We measured fourteen (14) whole-tree harvested (WTH) and fifteen (15) conventionally harvested (CH) sites and compared the productivity of the 10–14 year old Size: KB.Key Words: Northern hardwoods, stocking, structure, growth.
When marking a northern hardwood stand for uneven-aged management through individual-tree or small-group selec- tion, the manager comes face-to-face with the question of how much basal area to leave in the residual stand and how much of this basal area should be in sawtimber-sized trees.Canopy transmittance and residual stand structural features were measured inha circular plots established in recently harvested stands in 12 locations across northern Ontario.
For both trembling aspen- and white birch-dominated residual stands, canopy transmittance exhibited a negative exponential relationship with basal area Author: William C Parker, Mahadev Sharma.
