Wood decay elements include snags, down wood, root wads, tree stumps, litter, duff, broomed or diseased branches, and partially dead trees, all of which contribute to ecological processes and biodiversity of the forest ecosystem. Down wood can serve as reservoirs for moisture and mycorrhizal fungi beneficial to the health and growth of commercial tree species. Decaying wood, leaf litter, small twigs, and roots contribute nutrients and structure to humus and soil organic matter, and host microbes that play beneficial roles in nitrogen cycles and other processes. Snags and down wood provide nurse functions for tree and shrub species, and can aid in restoration of degraded forest environments. Various elements of wood decay provide habitat for many species of wildlife including invertebrates, amphibians, reptiles, birds, and mammals. Fire can influence the amounts and distributions of wood decay elements and enhance or detract desired ecosystem processes, depending on severity, charring, soil temperature, and other factors. Managing wood decay elements for ecosystem processes entails better understanding decay dynamics, the role of coarse wood in soil, the role of wood decay in carbon cycling and sequestration, and other considerations.

Since 1960, the Forest Service has been guided by the multiple-use concept, which recognizes five major uses for public lands-timber, water, range, recreation, and fish and wildlife habitat-and mandates that all five should be equally considered in management plans.

October 2012—When you hear the word “ecosystem,” what comes to mind? A forest? A river, maybe? Well, how about a city? It turns out, the green spaces in our urban areas can offer a range of ecosystem services, just like forests and rivers. Station scientists are working to better understand cities as ecosystems and demonstrate how nearby nature provides important benefits and services. (4:19)

A century of effective fire suppression has radically transformed many forested landscapes on the east side of the Cascades. Managers of dry forests critically need information to help plan for and implement forest restoration. Management priorities include the stabilization of fire regimes and the maintenance of habitat for the northern spotted owl and other old-forest associates.

The Northwest Forest Plan (the Plan) identifies adaptive management as a central strategy for effective implementation. Despite this, there has been a lack of any systematic evaluation of its performance.

A primary mission of the U.S. Department of Agriculture Forest Service is multiple resource management, and one of the emerging themes is forest restoration. The National Silviculture Workshop, a biennial event co-sponsored by the Forest Service, was held May 7-10, 2007, in Ketchikan, Alaska, with the theme of "Integrated Restoration of Forested Ecosystems to Achieve Multiresource Benefits." This proceedings presents a compilation of state-of-the-art silvicultural research and forestry management papers that demonstrates integrated restoration to yield multiple resource benefits. These papers highlight national perspectives on ecosystem services, forest restoration and climate change, and regional perspectives on forest restoration and silvicultural practices to achieve multiple resource benefits from researchers and forest practitioners working in a broad array of forest types in the United States.

This synthesis provides an ecological foundation for management of the diverse ecosystems and fire regimes of North America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Although a large amount of scientific data on fire exists, most of those data have been collected at small spatial and temporal scales. Thus, it is challenging to develop consistent science-based plans for large spatial and temporal scales where most fire management and planning occur. Understanding the regional geographic context of fire regimes is critical for developing appropriate and sustainable management strategies and policy. The degree to which human intervention has modified fire frequency, intensity, and severity varies greatly among different ecosystems, and must be considered when planning to alter fuel loads or implement restorative treatments. Detailed discussion of six ecosystems--ponderosa pine forest (western North America), chaparral (California), boreal forest (Alaska and Canada), Great Basin sagebrush (intermountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern United States)--illustrates the complexity of fire regimes and that fire management requires a clear regional focus that recognizes where conflicts might exist between fire hazard reduction and resource needs. In some systems, such as ponderosa pine, treatments are usually compatible with both fuel reduction and resource needs, whereas in others, such as chaparral, the potential exists for conflicts that need to be closely evaluated. Managing fire regimes in a changing climate and social environment requires a strong scientific basis for developing fire management and policy.

Conservation of biodiversity serves a number of human needs, including maintenance of ecosystem services that are critical to the sustainability of all life. Effective biodiversity conservation will require better landowner incentives for restoration and protection of ecosystems. Many services produced from healthy, functioning landscapes are not well recognized in current conservation incentive structures, including sequestering or storing carbon in trees and soil, providing fish and wildlife habitat, filtering water, and reducing damages from natural disasters. Most existing incentive programs pay landowners to protect and restore a specific service rather than the suite of services produced from well-functioning ecosystems.

The concept of ecosystem services has emerged as a way of framing and describing the comprehensive set of benefits that people receive from nature. These include commonly recognized goods like timber and fresh water, as well as processes like climate regulation and water purification, and aesthetic, spiritual, and cultural benefits. The USDA Forest Service has been exploring use of the framework of ecosystem services as a way to describe goods and services provided by federal lands and attract and build partnerships with stakeholders and nongovernmental organizations. More recently, the agency has sought place-based example applications of the ecosystem service framework to explore its possible use as a tool to guide forest management, and better illustrate the concept for policymakers, managers, and potential national forest partners.

The past decade has seen resurgence in interest in gathering wild plants and fungi in cities. In addition to gathering by individuals, dozens of groups have emerged in U.S., Canadian, and European cities to facilitate access to nontimber forest products (NTFPs), particularly fruits and nuts, in public and private spaces. Recent efforts within cities to encourage public orchards and food forests, and to incorporate more fruit and nut trees into street tree planting programs indicate a growing recognition among planners that gathering is an important urban activity.

The U.S. Forest Service has adopted the concept and language of ecosystem services to describe the beneficial outcomes of national forest management. We review the economic theory of ecosystem services as it applies to public lands management, and consider what it implies about the types of biophysical and other data that are needed for characterizing management outcomes as changes in ecosystem services. Our intent is to provide a guide to policymakers, managers, researchers, and others for evaluating and describing the tradeoffs involved in the management of public lands. Characterizing ecosystem services fundamentally is about explaining the benefits of national forests to the American public, with an emphasis on addressing their interests and concerns about how public lands are managed. Our hope is that this report will foster dialog about what people value about national forests and how public land management agencies might best go about securing those benefits.

We reviewed the literature to synthesize what is known about the use of fire to maintain and restore oak forests, woodlands, and savannas of the upper Midwestern United States, with emphasis on Minnesota, Wisconsin, and Michigan.

The ecosystem services concept describes the many benefits people receive from nature. 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.".

During September 19-20, 2006, a conference was held at the University of Washington Botanic Gardens, Seattle, WA, with the title "Meeting the challenge: invasive plants in Pacific Northwest Ecosystems." The mission of the conference was to create strategies and partnerships to understand and manage invasions of non-native plants in the Pacific Northwest. The audience included over 180 professionals, students, and citizens from public and private organizations responsible for monitoring, studying, or managing non-native invasive plants. This proceedings includes twenty-seven papers based on oral presentations at the conference plus a synthesis paper that summarizes workshop themes, discussions, and related information. Topics include early detection and rapid response; control techniques, biology, and impacts; management approaches; distribution and mapping of invasive plants; and partnerships, education, and outreach.
