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.

Download or read book Representativeness Assessment of Research Natural Areas on National Forest System Lands in Idaho written by Steven K. Rust and published by . This book was released on 2000 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A representativeness assessment of National Forest System (N FS) Research Natural Areas in ldaho summarizes information on the status of the natural area network and priorities for identification of new Research Natural Areas. Natural distribution and abundance of plant associations is compared to the representation of plant associations within natural areas. Natural distribution and abundance is estimated using modeled potential natural vegetation, published classification and inventory data, and Heritage plant community element occurrence data. Minimum criteria are applied to select only viable, high quality plant association occurrences. In assigning natural area selection priorities, decision rules are applied to encompass consideration of the adequacy and viability of representation. Selected for analysis were 1,024 plant association occurrences within 214 natural areas (including 115 NFS Research Natural Areas). Of the 1,566 combinations of association within ecological sections, 28 percent require additional data for further analysis; 8, 40, and 12 percent, respectively, are ranked from high to low conservation priority; 13 percent are fully represented. Patterns in natural area needs vary between ecological section. The result provides an operational prioritization of Research Natural Area needs at landscape and subregional scales. Objective ranking criteria provide clear accounting of priority assignments that are easily updated to reflect changing information or conditions.

Download or read book Establishment Record for the Wellner Cliffs Research Natural Area written by Dennis E. Ferguson and published by . This book was released on 2006 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is the establishment report for Wellner Cliffs Research Natural Area (RNA), located on the Priest River Experimental Forest, Idaho Panhandle National Forests. The RNA features vegetation on dry cliffs that are embedded in mid-elevation moist western hemlock/western redcedar/grand fir forests. Immediately below the cliffs is riparian habitat that supports many wetland species, including a disjunct west coast moss, Ulota megalospora, whose first known occurrence in Idaho is in this RNA. This establishment report documents the boundaries of the RNA, the objectives for the RNA, its features, description of values, and management prescription.

This book was released on 1990 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes each of 68 ecological surveys conducted from 1975 through 1988 on candidate and established Research Natural Areas in the Pacific Southwest Region of the USDA Forest Service. These surveys represent an important but largely unknown contribution to the ecological literature of California. For each summary, information on location, target elements, distinctive features, physical characteristics, association types, plant diversity, and conflicting impacts is provided. Comparisons are made between similar vegetation types at different sites. Tables and appendices summarize the plant communities, target elements, rare plants, and trees occurring on all areas. Maps of all areas and photographs of most areas are included.

Download or read book This Land written by Robert H. Mohlenbrock and published by Univ of California Press. This book was released on 2006-03-15 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part armchair travelogue, part guide book, this projected three-volume series—divided into the western, central, and eastern United States—will introduce readers to all 155 national forests across the country. This Land is the only comprehensive field guide that describes the natural features, wildernesses, scenic drives, campgrounds, and hiking trails of our national forests, many of which—while little known and sparsely visited—boast features as spectacular as those found in our national parks and monuments. Each entry includes logistical information about size and location, facilities, attractions, and associated wilderness areas. For about half of the forests, Robert H. Mohlenbrock has provided sidebars on the biological or geological highlights, drawn from the "This Land" column that he has written for Natural History magazine since 1984. Superbly illustrated with color photographs, botanical drawings, and maps, this book is loaded with information, clearly written, and easy to use. This volume covers national forests in: Arkansas, Colorado, Louisiana, Minnesota Missouri, Montana, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Wyoming
