Book Synopsis Flora of the Pacific Northwest by : C. Leo Hitchcock
Download or read book Flora of the Pacific Northwest written by C. Leo Hitchcock and published by University of Washington Press. This book was released on 2018-09-17 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flora of the Pacific Northwest, first published in 1973, became an instant classic for its innovative style of providing species descriptions in the identification keys, and for its comprehensive illustrations of nearly all treated taxa (species, subspecies, and varieties). Students rely on it as an essential primer, while veteran botanists and natural resource managers use it as the definitive reference for the region�s flora. This completely revised and updated edition captures the advances in vascular plant systematics over the decades since publication of the first edition. These advances, together with significant changes in plant nomenclature, the description of taxa new to science from the region, and the recent documentation of new native and nonnative species in the Pacific Northwest required a thorough revision of this authoritative work. Flora of the Pacific Northwest covers all of Washington, the northern half of Oregon, Idaho north of the Snake River Plain, the mountainous portion of western Montana, and the southern portion of British Columbia. It accounts for the wild-growing native and introduced vascular plants falling within those boundaries and includes: Treatment of 5,545 taxa (more than 1,000 taxa added from the first edition) Illustrations for 4,716 taxa (1,382 more than the first edition) Nomenclature changes for more than 40 percent of the taxa included in the first edition These enhancements make this new edition the most comprehensive reference on Pacific Northwest vascular plants for professional and amateur botanists, ecologists, rare plant biologists, plant taxonomy instructors, land managers, nursery professionals, and gardeners.

Book Synopsis Nonnative Invasive Plants of Pacific Coast Forests by : Andrew N. Gray
Download or read book Nonnative Invasive Plants of Pacific Coast Forests written by Andrew N. Gray and published by . This book was released on 2011 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonnative plants affect the composition and function of natural and managed ecosystems and have large economic effects through lost or degraded land use and eradication costs. In spite of their importance, very little comprehensive information on the abundance, distribution, and impact of nonnative invasive plants is available. The objective of this study was to prioritize a list of nonnative invasive plants affecting forest lands in the Pacific coastal states of California, Oregon, and Washington, and provide enough detail in nontechnical language and photos of different stages of plant development to allow reliable identification in the field. Information was synthesized from a variety of national, regional, and state lists, assessments, and botanical guides. The final list was designed to capture species believed to be most prevalent or problematic and to be used for strategic forest inventories like the Forest Inventory and Analysis Program. Identification of the several hundred nonnative invasive species present in the region requires substantial taxonomic experience; a prioritized short list of species with practical identification tips can be a good place for novice botanists and large-scale monitoring efforts to start.

Book Synopsis Research Natural Area Needs in the Pacific Northwest by : C. T. Dyrness
Download or read book Research Natural Area Needs in the Pacific Northwest written by C. T. Dyrness and published by . This book was released on 1975 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Natural Areas are examples of typical and distinctive natural ecosystems and habitats reserved for scientific and educational use. This outline of the minimal Research Natural Area system needed to provide adequate field laboratories for ecological, environmental, and land management research was developed by an interinstitutional, interdisciplinary working group. Natural area needs were first described on the basis of individual organisms, habitats, or ecosystems which should be represented. These "cells," the basic building blocks in defining the total scope of the system, considered terrestrial and aquatic environments as well as rare and endangered species. Identified cells were matched against existing Research Natural Areas to determine which were already filled. The remaining, unfilled cells were then tentatively grouped as units which were listed as Research Natural Area needs. A minimal Research Natural Area system for Oregon and Washington requires approximately 360 tracts which, in turn, incorporate over 770 individual cells (ecosystems, habitats, or organisms). Since 60 Research Natural Areas are already established, about 300 additional areas are needed. These remaining needs were assigned a priority (low, medium, or high) based on importance and degree to which they are endangered, as well as identified as to the Federal, State, or private agency or institution most likely to be able to provide a tract of that type. The purpose of Research Natural Areas, their place in land planning, history of Research Natural Area activities in the Pacific Northwest, and general observations and recommendations on unresolved problems are also outlined.
