- Landowner behavior is a major determinant of land use and land cover changes. an important consideration for policy analysts concerned with global change. Study of landowner behavior aids in designing more effective incentives for inducing land use and land cover changes to help mitigate climate change by reducing net greenhouse gas emissions. Afforestation, deforestation, reforestation, and timber harvest are the most frequent land management practices that influence forest carbon stocks and flux. Research studies provide estimates of how private landowners respond to market signals and...AuthorsRalph AligKeywordsSourceSilva Fennica. 37(4): 511-527Year2003
- The STHARVEST computer application is Windows-based, public-domain software used to estimate costs for harvesting small-diameter stands or the small-diameter component of a mixed-sized stand. The equipment production rates were developed from existing studies. Equipment operating cost rates were based on November 1998 prices for new equipment and wage rates for the Pacific Northwest. There are four ground-based and two cable harvesting systems. Harvesting costs can be estimated for both clearcutting and partial cutting for an average tree size ranging from 1 to 80 or 150 cubic feet...AuthorsRoger D. Fight, Xiaoshan Zhang, Bruce R.

- The paper presents an approach for delimiting communities in the Northwest Forest Plan (NWFP) region of the Pacific Northwest that responds to the need to assess impacts and issues associated with broad-scale ecosystem management. Census block groups are aggregated to provide an alternative to more commonly used geographic delimitations of communities, specifically census places. With the block group aggregation approach, census data can be applied to almost 1.5 million more people in the NWFP region than would be represented by using census places. The delimitation of community boundaries...AuthorsEllen DonoghueKeywordsSourceGen. Tech. Rep. PNW-GTR-570.

- Improved understanding of the relationships between human communities and forests is necessary to understanding how alternative forest management policies and practices can affect different communities. This knowledge also enhances our ability to formulate plans that are responsive to the needs and concerns of local communities, thus reducing polarization and related social and economic costs. In December 1997, an interdisciplinary panel representing academic backgrounds in sociology, anthropology, geography, psychology, economics, and recreation gathered in Oregon to discuss relationships...AuthorsLinda E.

- The Hidden Forest Values Conference brought together a diverse assemblage of local, state, and federal agencies, tribal governments, traditional users, landholders, cottage enterprises and other nontimber forest products (NTFP) related businesses, scientists, and experts. The purpose of this forum was to exchange information, cooperate, and raise awareness of issues on sustainable and equitable, environmentally and economically viable opportunities for NTFP in Alaska. This discourse sought a balance of development and sustainability, with respect for traditional uses. Nontimber forest...Authorscomps Alaska Boreal Forest CouncilSourceGen. Tech. Rep. PNW-GTR-579.

- Determining the specific mix of fire-fighting resources for a given fire is a necessary condition for identifying the minimum of the Cost Plus Net Value Change (C+NVC) function. Current wildland fire management models may not reliably do so. The problem of identifying the most efficient wildland fire organization is characterized mathematically using integer-programming techniques. This mathematical exposition is then solved using the LINGO optimization language. Sensitivity analysis is conducted on model inputs to demonstrate the flexibility of the model architecture. Further, the model...AuthorsGeoffrey Donovan, Douglas B. RideoutSourceForest Science. 49(2): 331-335Year2003
- This handbook is a companion to the Handbook to Strategy 1 Fungal Species in the Northwest Forest Plan, Gen. Tech. Rep. PNW-GTR-476, published in October 1999. It includes 73 record-of-decision (ROD)-listed fungal species not contained in the first handbook, as well as updated site, field, and collecting forms; an expanded set of artificial keys to all fungal species from both handbooks; and an updated, partially illustrated glossary. The main purpose of this handbook is to help facilitate the survey, collection, and handling of potential ROD-listed fungal species by USDA Forest Service...AuthorsMichael A.

- As it becomes increasingly apparent that human activities are partly responsible for global warming, the focus of climate change research is shifting from the churning out of assessments to the pursuit of science that can test the robustness of existing models. The questions now being addressed are becoming more challenging: Can water-use efficiency of plants keep up with rising temperatures? Will we see a greening period for some decades, even a century, before facing a rapid browndown as threshold temperatures are reached? Or could the threshold be reached much sooner because of interacti...AuthorsSally DuncanSourceScience Findings.

- The summer of 2001 brought the second-worst drought on record in Oregon, resulting in historically low streamflows and reservoir levels, stressed aquatic ecosystems, and even dramatic confrontations between irrigators and federal resource agencies in the Klamath basin. These events underscore the critical and growing importance of water availability and allocation in the Pacific Northwest. Yet at the scale of large river basins, such as the Willamette River in western Oregon, we have an imperfect picture of how much water of what quality is available where and when. Having accurate...AuthorsSally DuncanSourceScience Findings. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. December (49): 1-5Year2002
- The question has risen over whether forested wetlands in southeast Alaska are suitable for sustainable timber production. A significant factor limiting forest productivity in this region is excess soil moisture. Very little is known about the soil conditions that influence tree growth on forested wetlands. A research study was completed to provide information on the growth of trees on these lands, resulting in an administrative decision to leave 100,000 acres of forested wetland in the timber base on the Tongass National Forest.The forested wetland research provided information about soil...AuthorsSally DuncanSourceScience Findings.
