Book Description
This summary report provides an overview of findings from the fourth annualized inventory of Iowa forests based on data collected from 2012 to 2018. Forest land area remained stable at 2.9 million acres, and 69 percent of forest land is in the oak/hickory forest-type group. Forests in the State continue to mature, with 72 percent in large diameter stands and 50 percent in stands older than 60 years of age. Total live-tree net volume on timberland is 4.4 billion cubic feet, and 69 percent of that volume is in growing-stock trees. Decreases in gross growth (7 percent) and mortality (2 percent) between 2012 and 2018 resulted in a 14 percent decrease in annual net growth of growing-stock trees to 61 million cubic feet. Additional information on land use change, fragmentation of forest land, ownership, urban forests, species composition, stand structure, forest carbon, down woody material, regeneration, invasive plants, forest pests, tree health, and timber products output are also presented. A detailed interactive report is available at https://doi.org/10.2737/NRS-RB-128-INT, and supplemental information, including (1) tables summarizing quality assurance, (2) a core set of tabular estimates for a variety of forest resources, and (3) user and database guides for P2 and P2+ protocols, can be accessed at https://doi.org/10.2737/NRS-RB-128.

Book Description
It is increasingly recognized that the economic value of forests is not merely the production of timber. Forests provide other key ecosystem services, such as being sinks for greenhouse gases, hotspots of biodiversity, tourism and recreation. They are also vitally important in preventing soil erosion and controlling water supplies, as well as providing non-timber forest products and supporting the livelihoods of many local people. This handbook provides a detailed, comprehensive and broad coverage of forest economics, including traditional forest economics of timber production, economics of environmental role of forests, and recent developments in forest economics. The chapters are grouped into six parts: fundamental topics in forest resource economics; economics of forest ecosystems; economics of forests, climate change, and bioenergy; economics of risk, uncertainty, and natural disturbances; economics of forest property rights and certification; and emerging issues and developments. Written by leading environmental, forest, and natural resource economists, the book represents a definitive reference volume for students of economics, environment, forestry and natural resource economics and management.

Book Description
From Iowa Territory’s nail-bitingly close referenda for statehood to the rise and subsequent erasure of German language media, Atlas of Iowa examines the state’s geography, demographics, agriculture, and political/cultural patterns. Drawing upon archival materials and synthesizing little-known secondary sources, the authors of this thematic atlas have pulled together a comprehensive map series that depicts Iowa’s complex, unique story of challenging human-environmental interaction. The narrative themes are conveyed both verbally and visually, allowing many of the state’s cultural debates to come alive. From Iowa’s rise to becoming a national leader in aspects of higher education and green energy development to its oft-critiqued social fabric, Atlas of Iowa reveals the rich, complicated, and diverse heritage of the Hawkeye State.

Book Description
Introduction to Forestry and Natural Resources, Second Edition, presents a broad, completely updated overview of the profession of forestry. The book details several key fields within forestry, including forest management, economics, policy, utilization and forestry careers. Chapters deal specifically with forest regions of the world, landowners, forest products, wildlife habitats, tree anatomy and physiology, and forest disturbances and health. These topics are ideal for undergraduate introductory courses and include numerous examples and questions for students to ponder. There is also a section dedicated to forestry careers. Unlike other introductory forestry texts, which focus largely on forest ecology rather than practical forestry concepts, this book encompasses the economic, ecological and social aspects, thus providing a uniquely balanced text. The wide range of experience of the contributing authors equips them especially well to identify missing content from other texts in the area and address topics currently covered in corresponding college courses. Covers the application of forestry and natural resources around the world with a focus on practical applications and graphical examples Describes basic techniques for measuring and evaluating forest resources and natural resources, including fundamental terminology and concepts Includes management policies and their influence at the local, national and international levels

Book Description
"My major goal in this book is to provide information on the natural history of the snakes and lizards of Iowa that will be useful to professional and amateur herpetologists, students, wildlife biologists, and all general readers interested in these fascinating creatures. I have combined general information with technical details about the morphology, distribution, ecology, behavior, and reproduction of each species and subspecies of snake and lizard found in Iowa"--

Book Description
In 2010, while editing a report on the effects of climate change in Iowa, ecologist Cornelia Mutel came to grips with the magnitude and urgency of the problem. She already knew the basics: greenhouse gas emissions and global average temperatures are rising on a trajectory that could, within decades, propel us beyond far-reaching, irreversible atmospheric changes; the results could devastate the environment that enables humans to thrive. The more details she learned, the more she felt compelled to address this emerging crisis. The result is this book, an artful weaving together of the science behind rising temperatures, tumultuous weather events, and a lifetime devoted to the natural world. Climate change isn’t just about melting Arctic ice and starving polar bears. It’s weakening the web of life in our own backyards. Moving between two timelines, Mutel pairs chapters about a single year in her Iowa woodland with chapters about her life as a fledgling and then professional student of nature. Stories of her childhood ramblings in Wisconsin and the solace she found in the Colorado mountains during early adulthood are merged with accounts of global environmental dilemmas that have redefined nature during her lifespan. Interwoven chapters bring us into her woodland home to watch nature’s cycles of life during a single year, 2012, when weather records were broken time and time again. Throughout, in a straightforward manner for a concerned general audience, Mutel integrates information about the science of climate change and its dramatic alteration of the planet in ways that clarify its broad reach, profound impact, and seemingly relentless pace. It is not too late, she informs us: we can still prevent the most catastrophic changes. We can preserve a world full of biodiversity, one that supports human lives as well as those of our myriad companions on this planet. In the end, Mutel offers advice about steps we can all take to curb our own carbon emissions and strategies we can suggest to our policy-makers.

Book Description
Assessing fifty years of the National Historic Preservation Act (NHPA), passed in 1966, this volume examines the impact of this key piece of legislation on heritage practices in the United States. The editors and contributing authors summarize how we approached compliance in the past, how we approach it now, and how we may approach it in the future. This volume presents how federal, state, tribal entities, and contractors in different regions address compliance issues; examines half a century of changes in the level of inventory, evaluation and mitigation practices, and determinations of eligibility; describes how the federal and state agencies have changed their approach over half a century; the Act is examined from the Federal, SHPO, THPO, Advisory Council, and regional perspectives. Using case studies authored by well-known heritage professionals based in universities, private practice, tribes, and government, this volume provides a critical and constructive examination of the NHPA and its future prospects. Archaeology students and scholars, as well heritage professionals, should find this book of interest.

Book Description
Wind, solar, geothermal, biofuel, hydro, and other non-traditional energy sources show promise as alternatives to fossil fuels and may provide a sustainable source of energy in increasingly uncertain energy markets. However, these new sources of energy face their own set of political, administrative, and legal challenges. Underexplored in both academic and policy settings, this book provides valuable insights on how existing regulatory regimes in the United States interact with the broad goal of developing green energy and curbing global climate change.
