Mp761: Considerations And Recommendations For Retaining Woody Biomass On Timber Harvest Sites In Maine, Jeffrey G. Benjamin
This report and associated guidelines focus on the amount and type of woody biomass that should be retained in the forest after a harvest operation to protect soil productivity, water quality, and site-level biodiversity. Woody biomass, defined from a forest operations perspective, is comprised of logging residues, previously unmerchantable stems, and other such woody material harvested directly from the forest typically for the purposes of energy production. In the broadest sense woody biomass is the total mass of roots, stem, branches, bark and leaves of all tree and shrub species (live and dead) in the forest. Under the broad definition ...

Mathematics, Physics, and Computer Science Faculty Articles and Research
Light Detection and Ranging (LiDAR) systems can be used to estimate both vertical and horizontal forest structure. Woody components, the leaves of trees and the understory can be described with high precision, using geo-registered 3D-points. Based on this concept, the Effective Plant Area Indices (PAIe) for areas of Korean Pine (Pinus koraiensis), Japanese Larch (Larix leptolepis) and Oak (Quercus spp.) were estimated by calculating the ratio of intercepted and incident LIDAR laser rays for the canopies of the three forest types. Initially, the canopy gap fraction (GLiDAR) was generated by extracting the LiDAR data reflected from the canopy surface, or ...

The Effects Of The 1996 U.S.-Canada Softwood Lumber Agreement On The Industrial Users Of Lumber: An Event Study, 2009 University of British Columbia
The Effects Of The 1996 U.S.-Canada Softwood Lumber Agreement On The Industrial Users Of Lumber: An Event Study, Nisha Malhotra, Sumeet Gulati
In this article, we analyze whether the Softwood Lumber Agreement between the United States and Canada imposed significant economic costs on industries that use softwood lumber in the United States. To ascertain this impact, we use an event study. Our event study analyzes variations in the stock prices of lumber-using firms listed at the major stock markets in the United States. We find that the news of events leading to the Softwood Lumber Agreement had significant negative impacts on the stock prices of industries using softwood lumber. The average reduction of stock prices for our sample of firms was approximately ...
