Monitoring: Specifically for Tree Regeneration in Forests

# 18 Clearcut Studies
  • Objective:
    To monitor regeneration of birch trees growing on clearcut areas. The data collected provides an excellent demonstration of the financial and silvicutural capabilities of the management programs.
  • Objective:
    To determine the effects of 3 cutting and 3 seedbed treatments on white ash regeneration.
  • Objective:
    1) To document survival and development of regeneration with various characteristics, after overstory removal.
    2) To follow the survival, growth and development of individual spruce-fir.
  • Objective:
    1) To compare the establishment and growth of 10 species of forest plants under varying levels of light exposure and soil moisture.
    2) To isolate the effects of light exposure, soil moisture, temperature and soil chemical content so that the contribution of each can be determined.
  • Objective:
    To determine the effect of 4 levels of cutting on advanced regeneration present prior to cutting and on the establishment and growth of additional regeneration.
  • Objective:
    To establish the growth response obtainable from fertilization and the time duration that treatments affect production.
  • Objective:
    To consolidate into one study all existing regeneration records and to schedule periodic remeasurement of these plots to enable researchers to refine existing guidelines.
  • Objective:
    1) To determine long-term differences in the volume and value growth and yield of Allegheny hardwood stands under different management systems.
    2) To determine the effect of these management systems on the establishment of regeneration.
  • Objective:
    1) To determine the average deer density which will allow natural regeneration of desirable Allegheny hardwood timber species at adequate stocking levels in stands managed under even-age silviculture.
    2) To determine the effects of known herd-size on browse-use over a range of regeneration conditions in Allegheny Plateau cherry-maple stands.
    3) To determine if deer density impacts songbird, small mammal, shrub and herb communities.
  • Objective:
    To characterize a) growth of residual trees and stands and b) regeneration after thinning treatments involving differing levels of felling unmerchantable hemlock.
  • Objective:
    To observe long term impacts of forest regeneration under various overstory densities.
