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.

The 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.

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

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.

"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"--
