The Influences Of Conventional And Low Density Thinning On Leaf Area, Growth, And Growing Space Relationships Of Eastern White Pine (Pinus Strobus L.), Christopher Henry Guiterman
The Influences Of Conventional And Low Density Thinning On Leaf Area, Growth, And Growing Space Relationships Of Eastern White Pine (Pinus Strobus L.), Christopher Henry Guiterman
Electronic Theses and Dissertations
Despite the commercial importance and widespread management of eastern white pine {Pinus strobus L.) in the Northeast, surprisingly little is known about the effects of thinning on even-aged stand development. To address this, patterns of leaf area, bole form, volume growth, and growth efficiency - defined as volume increment per unit leaf area - were examined over a 17-year period within a thinning study in central Maine designed to compare the conventional B-line and low density thinning regimes. At the tree-level, many of the effects of thinning were as expected. Heavier, low density thinning resulted in significantly larger and deeper …
A Case Study Approach For Assessing Operational And Silvicultural Performance Of Whole-Tree Biomass Harvesting In Maine, Charles E. Coup
A Case Study Approach For Assessing Operational And Silvicultural Performance Of Whole-Tree Biomass Harvesting In Maine, Charles E. Coup
Electronic Theses and Dissertations
In the Northeastern United States, re-emerging markets for renewable energy are driving interest in increasing the harvest of underutilized biomass material from Maine’s forest. These markets may offer opportunities for forest managers to implement silvicultural treatments that have previously been foregone due to their high cost. However, many operational challenges arise in using current harvesting systems to harvest biomass material profitably while simultaneously achieving silvicultrual objectives. This research uses a case study approach to analyzing some of the possibilities and obstacles in implementing biomass harvesting in Maine. The first three studies investigate a factorial silvicultural and operational case study involving …
