Book Description
The second full annual inventory of Iowa's forests (2004-2008) reports more than 3 million acres of forest land, almost all of which is timberland (98 percent), with an average volume of more than 1,000 cubic feet of growing stock per acre. American elm and eastern hophornbeam are the most numerous tree species, but silver maple and bur oak predominate in terms of live tree volume. Iowa's forest land is comprised of 65 percent sawtimber, 19 percent poletimber, and 16 percent sapling/seedling or nonstocked size classes. Average annual net growth of growing-stock trees on Iowa's timberland increased during the past decade to the current estimate of nearly 105 million cubic feet. This report includes additional information on forest attributes, land use change, carbon, timber products, and forest health. A DVD included in this report includes 1) descriptive information on methods, statistics, and quality assurance of data collection, 2) a glossary of terms, 3) tables that summarize quality assurance, 4) a core set of tabular estimates for a variety of forest resources, and 5) a Microsoft Access database that represents an archive of data used in this report, with tools that allow users to produce customized estimates.

Introduction to Forestry and Natural Resources
Author: Donald L. Grebner
Publisher: Academic Press
ISBN: 0128190760
Category : Technology & Engineering
Languages : en
Pages : 513
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

The Emerald Horizon
Author: Cornelia F. Mutel
Publisher: University of Iowa Press
ISBN: 1587297477
Category : History
Languages : en
Pages : 329
Book Description
In The Emerald Horizon, Cornelia Mutel combines lyrical writing with meticulous scientific research to portray the environmental past, present, and future of Iowa. In doing so, she ties all of Iowa's natural features into one comprehensive whole. Since so much of the tallgrass state has been transformed into an agricultural landscape, Mutel focuses on understanding today’s natural environment by understanding yesterday’s changes. After summarizing the geological, archaeological, and ecological features that shaped Iowa’s modern landscape, she recreates the once-wild native communities that existed prior to Euroamerican settlement. Next she examines the dramatic changes that overtook native plant and animal communities as Iowa’s prairies, woodlands, and wetlands were transformed. Finally she presents realistic techniques for restoring native species and ecological processes as well as a broad variety of ways in which Iowans can reconnect with the natural world. Throughout, in addition to the many illustrations commissioned for this book, she offers careful scientific exposition, a strong sense of respect for the land, and encouragement to protect the future by learning from the past. The “emerald prairie” that “gleamed and shone to the horizon’s edge,” as botanist Thomas Macbride described it in 1895, has vanished. Cornelia Mutel’s passionate dedication to restoring this damaged landscape—and by extension the transformed landscape of the entire Corn Belt—invigorates her blend of natural history and human history. Believing that citizens who are knowledgeable about native species, communities, and ecological processes will better care for them, she gives us hope—and sound suggestions—for the future.
