A 1976 National Academy of Science study evaluated the performance of wood products with respect to energy use and wood utilization. In the 1990’s the need to update and expand the environmental measures was recognized. An adhoc committee was formed resulting in a National Research Council Symposium and Proceedings ‘Wood in our Future, The Role of life-cycle Analysis’ suggesting a framework to collect and update massive amounts of data on forests and wood uses and their environmental impacts. CORRIM, a not for profit research consortium of 15 institutions was formed in 1996. DOE funded their development of an extensive research plan to look at the life cycle impacts of wood production and uses across supply regions and many products. Forest Service and private donor grants funded the research for the first of several special issue publications in 2005 reporting on the environmental performance of wood in building materials. Primary surveys of many mills and reliance on the USFS Forest Inventory Surveys are critical inputs. The impacts of recent updating efforts are revealed in changes in the hierarchy of displacement efficiencies for different forest management alternatives and many different wood uses. Scenarios characterize the potential impact of new innovations and carbon mitigation policies on wood carbon stores and fossil carbon emissions. The report focuses on the changes in life cycle impacts and the leverage to store more carbon in wood and displace more fossil emissions through forest management, wood and energy processing, wood uses, architectural design and effective carbon negative policies.

Southern Forestry Practices: Costs and Trends

Estimates of the costs of forestry practices in the South have been reported since 1952 from surveys distributed to forest landowners across the southeastern United States. Since 1982, the survey has been reported every two years. As a continuation of the survey, 650 questionnaires were mailed or emailed to private firms, public agencies, and individuals from 14 states across the South during the winter of 2016. The objectives of the survey are to better understand the costs of various forestry practices across the region for forest landowners. Representing the twenty-fourth version of this report, results of the 2016 survey are presented and compared to costs reported by prior surveys. For the 2016 survey, respondents were asked to report their cost for mechanical site preparation, planting, prescribed burning, chemical application, fertilization, fire protection, timber cruising, timber marking, precommercial thinning, and custodial management. Since 2012, the majority of costs decreased with the exception of chemical application, which increased by 20%. During this time, the producer price index also decreased by 8%, while the softwood lumber index increased by 14%. Adam Maggard, Auburn University.
The Magnitude of Variation in Results By Using Different Economic Contribution Analysis Approach Using IMPLAN

Economic contributions analysis of the forest products industries provides a snapshot of direct economic activity associated with given industries and other economic activities linked to those industries. These contributions have been estimated using various approaches in different states. This study demonstrates the magnitude of variation in results by using different methods in estimating economic contributions of forest products industries in Michigan. Results show that the simple multiplier approach overestimates the total economic contributions by 8% to 13%, compared to multi-industry approach.

Landslides in Coastal Oregon: How Geologic Conditions Affect Harvest Planning

Private timberlands in Oregon are subject to the standards of the Oregon Forest Practices Act. Following severe weather events of 1996 in which fatalities occurred as the result of landslides that originated on forest lands, studies were conducted regarding the relationship between forest conditions and slope stability. We address how rules for harvests on steep slopes evolved in response to concerns for public safety. This presentation will describe geologic conditions in the Oregon Coast Range and their influence on harvest planning. Paul Clements, Oregon Department of Forestry.

Following severe weather events of 1996 in which fatalities occurred as the result of landslides that originated on forest lands, studies were conducted regarding the relationship between forest conditions and slope stability. We address how rules for harvests on steep slopes evolved in response to concerns for public safety. An associated presentation will describe geologic conditions that influence harvest planning. This presentation will outline the current standards for commercial forestry operations where slope stability related public safety concerns are found to exist during harvest planning.

Use of Lidar-derived Forest and Topographic Characteristics to Classify Alternative Harvest System Options

As innovative harvest systems are developed, the extent to which they can be utilized on the landscape based on machine capabilities is often unclear to forest managers. In response, spatial decision support models may aid land managers in choosing appropriate logging systems based on topography and stand characteristics. Lidar and inventory data from 91 sample plots were used to model site characteristics for 2627 stands in the Slate Creek drainage on the Nez Perce Clearwater National Forest in North-Central Idaho, USA. Five harvest systems were then integrated into a decision support tool to characterize sites where use of these systems was feasible. Self-levelling shovel harvester-based logging systems were included to determine potential sites where use of the systems is possible based on landscape and stand conditions. Lidar-derived predictions for volume and trees per hectare were determined with model accuracies of 76.4% and 70.3%, and together with topographic characteristics it was determined that shovel harvester-based options were feasible for over 30% of the study area. Additionally, increasing operable slope for ground-based systems by 10% increased the area harvestable by 21%. Feasible harvest system classification using lidar-derived products allows managers to better evaluate operable capabilities of alternative harvest system options and may aid in evaluating potential application and impact of new logging systems at the landscape level as they evolve.
