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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Before any other influences began to fashion life and its lavish diversity, geological events created the initial environments--both physical and chemical--for the evolutionary drama that followed. Drawing on case histories from around the world, Arthur Kruckeberg demonstrates the role of landforms and rock types in producing the unique geographical distributions of plants and in stimulating evolutionary diversification. His examples range throughout the rich and heterogeneous tapestry of the earth's surface: the dramatic variations of mountainous topography, the undulating ground and crevices of level limestone karst, and the subtle realm of sand dunes. He describes the ongoing evolutionary consequences of the geology-plant interface and the often underestimated role of geology in shaping climate. Kruckeberg explores the fundamental connection between plants and geology, including the historical roots of geobotany, the reciprocal relations between geology and other environmental influences, geomorphology and its connection with plant life, lithology as a potent selective agent for plants, and the physical and biological influences of soils. Special emphasis is given to the responses of plants to exceptional rock types and their soils--serpentines, limestones, and other azonal (exceptional) substrates. Edaphic ecology, especially of serpentines, has been his specialty for years. Kruckeberg's research fills a significant gap in the field of environmental science by connecting the conventionally separated disciplines of the physical and biological sciences. Geology and Plant Life is the result of more than forty years of research into the question of why certain plants grow on certain soils and certain terrain structures, and what happens when this relationship is disrupted by human agents. It will be useful to a wide spectrum of professionals in the natural sciences: plant ecologists, paleobiologists, climatologists, soil scientists, geologists, geographers, and conservation scientists, as well as serious amateurs in natural history.
