Solomon. northern hardwood associations, contributing highly to the stand value on both agriculturally disturbed and dry or shallow-to-bedrock sites. Red oak regeneration in northern hardwood-oak stands is addressed under the section on even-age management. Mixed-wood stands are diverse, including 25 to 65Cited by: A significant increase occurred in the total number of seedlings and saplings from 2 to 5 years after felling. For Yellow Birch, residual stand densities of 30 and 50 sq. ft. b.a. gave a greater increase in % of stocked quadrats than did denser overstoreys. Residual stand density stand density Subject Category: PropertiesAuthor: T. W. Church. Data from three uneven-aged northern hardwood stands in New York State were analyzed to assess the effects of understory American beech (Fagus grandifolia Ehrh.) density on changes of small stems within the to cm diameter class during the first cutting cycle under single-tree selection gs show that the amount of understory American beech on a regeneration Author: Ralph D.

Old-Growth Characteristics in Northern Hardwood-Conifer Forests group selection, and SCE. Regeneration density and diversity can be limited by differing treatment effects on or interactions among light availability, competitive environment, substrate, and herbivory. Regeneration Responses to Management for Old-Growth Characteristics in Cited by: 8. Residual canopy cover did not significantly affect aspen density in 9-year-old regeneration (R2 = , P = ) but was negatively related to total height of 9-year-old codominant aspens (R2. 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.

About 20 acres was pure northern hardwoods with little hemlock influence; this section was used for the regeneration surveys. Harvesting occurred in the winter of , and stand conditions were similar to the clearcut. The residual basal area was about 40 ft2, ranging from about 20 to 80 ft2.

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
