Book excerpt: 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.
Download or read book Forest and Shade Trees of Iowa written by Peter J. van der Linden and published by University of Iowa Press. This book was released on 2011-07-15 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Back in print at last in a third edition, the classic Forest and Shade Trees of Iowa now has a wealth of full-color photographs and updated, reorganized information that will please both new and returning readers. Part 1 of this guide focuses on identification, with user-friendly keys to both summer and winter trees and illustrated descriptions of more than one hundred common species. The trees are arranged according to similarities in foliage; each entry includes a large scan of a leafy branch along with two or three smaller photos of buds, flowers, fruits, and winter twigs. The text contains a description of the species, its geographical distribution, and notes on how to distinguish it from similar species. Part 2 is divided into conifers and flowering trees and includes all trees native to Iowa, trees that are widely planted, invasive species, some less commonly planted trees, and tall native shrubs that might be mistaken for trees. The authors provide information about the natural history of individual trees, their ecological requirements, pests and diseases that affect them, and their usefulness for such different purposes as windbreaks, landscaping, wildlife plantings, fuel, lumber, and food. Following these two main parts, three shorter sections describe the planting and care of trees, Iowa’s forest communities, and good places to see trees in the state; a glossary and a bibliography are also included. A complete guide to Iowa’s trees, both native and introduced, full of hundreds of color photos, this new edition of Forest and Shade Trees of Iowa will be immensely useful to arborists, foresters, horticulturists, landscape architects, gardeners, and all Iowans and midwesterners who appreciate the beauty and value of trees and want to learn more about them.
