OWASHINGTON, D.C., JUNE 11, 2018—The USDA Forest Service today released a report that will serve as the scientific foundation for land management planning in western Washington, western Oregon, and northern California.

This report provides new cost estimates for carbon sequestration through afforestation in the United States. We extend existing studies of carbon sequestration costs in several important ways, while ensuring the transparency of our approach. We clearly identify all components of our cost estimates so that other researchers can reconstruct our results as well as use our data for other purposes. Our cost estimates have five distinguishing features: (1) we estimate costs for each county in the contiguous United States; (2) we include afforestation of rangeland, in addition to cropland and pasture; (3) our opportunity cost estimates account for capitalized returns to future development (including associated option values) in addition to returns to agricultural production; (4) we develop a new set of forest establishment costs for each county; and (5) we incorporate data on Holdridge life zones to limit afforestation in locations where temperature and moisture availability prohibit forest growth. We find that at a carbon price of $50/ton, approximately 200 million tons of carbon would be sequestered annually through afforestation. At a price of $100/ton, an additional 100 million tons of carbon would be sequestered each year. Our estimates closely match those in earlier econometric studies for relatively low carbon prices, but diverge at higher carbon prices. Accounting for climatic constraints on forest expansion has important effects on cost estimates.

Carbon storage and flux estimates for the two national forests in Alaska are provided using inventory data from permanent plots established in 1995–2003 and remeasured in 2004–2010. Estimates of change are reported separately for growth, sapling recruitment, harvest, mortality, snag recruitment, salvage, snag falldown, and decay. Although overall aboveground carbon mass in live trees did not change in the Tongass National Forest, the Chugach National Forest showed a 4.5 percent increase. For the Tongass National Forest, results differed substantially for managed and unmanaged forest: managed lands had higher per-acre rates of sequestration through growth and recruitment, and carbon stores per acre that were higher for decomposing downed wood, and lower for live trees and snags. The species composition of carbon stores is changing on managed lands, with a carbon mass loss for yellow-cedar but increases for red alder and Sitka spruce. On unmanaged lands, the Chugach National forest had carbon mass increases in Sitka spruce and white spruce, and the Tongass National Forest had increases in western redcedar and red alder.

Stem decays of living trees, known also as heart rots, are essential elements of wildlife habitat, especially for cavity-nesting birds and mammals. Stem decays are common features of old-growth forests of coastal Alaska, but are generally absent in young, managed forests. We offer several strategies for maintaining or restoring fungal stem decay in these managed forests that can be used to enhance specific types of wildlife habitat.

This handbook and financial app is a guide to help communities quickly determine if biomass energy projects might work for them so that this option is not overlooked. Its purpose is as a screening tool designed to save significant time, resources, and investment by weeding out those wood energy projects that may never come to fruition from those that have a chance of success. It establishes technical, financial, and social criteria and indicators to evaluate proposed biomass investment options. Through showcasing of successful projects using text, photos, video interviews, and diagrams, it facilitates virtual project planning and interaction with experts. The interactive wood energy financial app allows estimation of capital investment costs to facilitate project design and screening across a variety of wood energy options. The calculator can be accessed from the eBook or from the Web.

The Integrated Landscape Assessment Project (ILAP) was a multiyear effort to produce information, maps, and models to help land managers, policymakers, and others conduct mid- to broad-scale (e.g., watersheds to states and larger areas) prioritization of land management actions, perform landscape assessments, and estimate cumulative effects of management actions for planning and other purposes.

We developed a process to address terrestrial wildlife species for which management for ecosystem diversity may be inadequate for providing ecological conditions capable of sustaining viable populations. The process includes (1) identifying species of conservation concern, (2) describing source habitats, and other important ecological factors, (3) organizing species into groups, (4) selecting surrogate species for each group, (5) developing surrogate species assessment models; (6) applying surrogate species assessment models to evaluate current and historical conditions, (7) developing conservation considerations, and (8) designing monitoring and adaptive management. Following the application of our species screening criteria, we identified 209 of 700 species as species of concern on National Forest System lands east of the Cascade Range in Washington state. We aggregated the 209 species of conservation concern into 10 families and 28 groups based primarily on their habitat associations (these are not phylogenetic families). We selected 32 primary surrogate species (78 percent birds, 17 percent mammals, 5 percent amphibians) for application in northeastern Washington, based on risk factors and ecological characteristics. Our assessment documented reductions in habitat capability across the assessment area compared to historical conditions. We combined management considerations for individual species with other surrogate species to address multiple species. This information may be used to inform land management planning efforts currently underway on the Okanogan-Wenatchee and Colville National Forests in northeastern Washington.

The Aquatic and Riparian Effectiveness Monitoring Program focuses on assessing the degree to which federal land management under the aquatic conservation strategy (ACS) of the Northwest Forest Plan (NWFP) has been effective in maintaining and improving watershed conditions. We used stream sampling data and upslope/riparian geographic information system (GIS) and remote-sensing data to evaluate condition for sixth-field watersheds in each aquatic province within the NWFP area.

It highlights the importance of managing public and private lands sustainably to ensure these benefits continue into the future, and it closely aligns with the U.S. Forest Service (USFS) mission to "sustain the health, diversity, and productivity of the Nation's forests and grasslands to meet the needs of present and future generations.".

The Blue Mountains Adaptation Partnership was developed to identify climate change issues relevant to resource management in the Blue Mountains region, to find solutions that can minimize negative effects of climate change, and to facilitate transition of diverse ecosystems to a warmer climate.

This assessment evaluates the effects of future climate change on a select set of ecological systems and ecosystem services in Alaska’s Kenai Peninsula and Chugach National Forest regions. The focus of the assessment was established during a multi-agency/organization workshop that established the goal to conduct a rigorous evaluation of a limited range of topics rather than produce a broad overview.
