Book Description
This report highlights key findings from a test (“pilot”) of an interior Alaska forest inventory design. The pilot inventoried the forests of the Tanana Valley State Forest (TVSF) and the Tetlin National Wildlife Refuge (TNWR) in the Tanana River Valley of interior Alaska, covering 2.5 million ac. The inventory consisted of a systematic grid of 98 field-measured plots integrated with NASA’s Goddard- LiDAR/Hyperspectral/Thermal (G-LiHT) imaging system. We summarize and interpret basic resource information such as forest area, ownership, volume, carbon stocks in trees, ground layers, dead wood, and soils; and vegetation community structure and composition. The black spruce forest type covered 49 percent of the forested area. Most of the aboveground live tree biomass was found in Alaska birch and black spruce forest types, but white spruce forest types had the highest mean aboveground live tree biomass per acre. Standing dead tree biomass was 8 percent of the amount in the live tree pool, with the greatest amounts in the white spruce forest type. Soil carbon per acre in the measured layers was highest in black spruce forests and lowest in aspen forests. Biomass of ground layers (i.e., moss and lichen mats) was almost twice as high on black spruce forests than on other forest types. Shrub and grass cover were comparable among units, but forb cover was greater on TVSF than on TNWR. The design and protocols tested during this pilot were refined for the implementation of the large-scale inventory of forests of interior Alaska that started in 2016.

Book Description
This guide to the animals and plants found in the Tetlin National Wildlife Refuge includes charts and checklists to indicate habitat, diet, phenology, classifications, and seasonal status. The "Miscellaneous" section includes a log of the Alaska Highway through the refuge, township designations for the upper Tanana Valley, Beaufort wind scale codes, and sky codes.

Book Description
This book collates, reviews and synthesizes information on how soil organic carbon (SOC) stocks differ among major terrestrial biomes of the U.S.A. Information on soil inorganic carbon (SIC) stocks for different terrestrial biomes of the U.S.A. will also be presented. The book deliberates options for increasing SOC stocks and enhancing SOC sequestration in terrestrial biomes by soil and land-use management practices. It concludes with an overview of terrestrial biomes of the U.S.A. where targeted soil and land-use management practices may result in the greatest increases in SOC stocks and enhancements in SOC sequestration.

Book Description
A valuable working resource for professionals. An excellent text for advanced forestry students . . . This unique book provides students and professionals with a broad-based knowledge of contemporary silviculture theory and practice.Throughout, the authors emphasize fundamental questions of edaphic,physiographic, and climatic site factors, as well as ecologicalrelationships and silvical characteristics of major tree species.Updated and expanded to reflect the many scientific, socioeconomic,and public policy trends that have had a profound impact onsilviculture over the past decade, this Third Edition of RegionalSilviculture of the United States: * Brings together the knowledge and expertise of fourteen leadingexperts from around the nation * Provides a rational framework with which to critically assessforest data and to develop innovative silvicultural solutions * Features region-by-region coverage of the eleven major foresttypes in the continental U.S. and Alaska * Offers a detailed look at practices that promote a wide range offorest resources--from wood production and outdoor recreation, towildlife habitat and range forage production * Now includes more in-depth coverage of such crucial themes asbiodiversity, endangered species, habitat fragmentation, foresthealth, landscape management, neotropical migrants, and more "...silviculture is not reducible to a series of rules; it must beflexible and adaptable to a variety of conditions. Much of it is anart as well as a synthesis of ecology and economics. There is nosingle best answer to how a stand should be managed. Andinstitutional and societal constraints must be considered." --fromthe Preface by John W. Barrett Regional Silviculture of the United States, Third Edition is not a"cookbook,"offering pat recipes for solving "typical" silviculturalproblems. Instead, it arms those responsible for the developmentand care of forests with something far more valuable--a rationalframework for the analysis of forest data and the development ofinnovative solutions tailored to specific forest types and theshifting politicoeconomic constraints under which silviculturalistsmust work. One way in which this book achieves that goal is by providingreaders with a broad-based knowledge of contemporary silviculturetheory and practice. In chapters organized according to the elevenmajor forest regions of the continental U.S., fourteen recognizedexperts from around the nation--each of them a specialist in aparticular region of operation--offer their valuable insights andobservations on silviculture in general and on varioussilvicultural practices with which they are familiar. Throughout,the authors are attentive to fundamental considerations of edaphic,physiographic, and climatic site factors, as well as ecologicalrelationships and silvical characteristics of major treespecies. This Third Edition of John W. Barrett's classic has been revisedand expanded to encompass a number of important themes which haverisen to prominence within silviculture over the past decade,including biodiversity, endangered species, habitat fragmentation,forest health, landscape management, and neotropicalmigrants. Timely, authoritative, and comprehensive in scope, RegionalSilviculture of the United States, Third Edition is a valuableresource for foresters, forestry students, ecologists,environmental scientists, and all those concerned with development,management, and preservation of our most valuable nationaltreasure.

Book Description
Balancing Greenhouse Gas Budgets: Accounting for Natural and Anthropogenic Flows of CO2 and other Trace Gases provides a synthesis of greenhouse gas budgeting activities across the world. Organized in four sections, including background, methods, case studies and opportunities, it is an interdisciplinary book covering both science and policy. All environments are covered, from terrestrial to ocean, along with atmospheric processes using models, inventories and observations to give a complete overview of greenhouse gas accounting. Perspectives presented give readers the tools necessary to understand budget activities, think critically, and use the framework to carry out initiatives. Written by a combination of experts across career stages, presenting an integrated perspective for graduate students and professionals alike Includes sections authored by those involved in both early and later IPCC assessments Provides an interdisciplinary resource that spans many topics and methodologies in oceanic, land and atmospheric processes
