Download or read book Potential Vegetation Hierarchy for the Blue Mountains Section of Northeastern Oregon, Southeastern Washington, and West-central Idaho written by and published by . This book was released on 2007 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work described in this report was initiated during the Interior Columbia Basin Ecosystem Management Project (ICBEMP). The ICBEMP produced a broad-scale scientific assessment of ecological, biophysical, social, and economic conditions for the interior Columbia River basin and portions of the Klamath and Great Basins. The broad-scale assessment made extensive use of potential vegetation (PV) information. This report (1) discusses certain concepts and terms as related to PV, (2) describes how a PV framework developed for the broad-scale ICBEMP assessment area was stepped down to the level of a single section in the national hierarchy of terrestrial ecological units, (3) describes how fine-scale potential vegetation types (PVTs) identified for the Blue Mountains section were aggregated into the midscale portion of the PV hierarchy, and (4) describes the PVT composition for each of the midscale hierarchical units (physiognomic class, potential vegetation group, plant association group).

Download or read book Deep Canyon and Subalpine Riparian and Wetland Plant Associations of the Malheur, Umatilla, and Wallowa-Whitman National Forests written by Aaron Francis Wells and published by . This book was released on 2006 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide presents a classification of the deep canyon and subalpine riparian and wetland vegetation types of the Malheur, Umatilla, and Wallowa-Whitman National Forests. A primary goal of the deep canyon and subalpine riparian and wetland classification was a seamless linkage with the midmontane northeastern Oregon riparian and wetland classification provided by Crowe and Clausnitzer in 1997. The classification is based on potential natural vegetation and follows directly from the plant association concept for riparian zones. The 95 vegetation types classified across the three national forests were organized into 16 vegetation series, and included some 45 vegetation types not previously classified for northeastern Oregon subalpine and deep canyon riparian and wetland environments. The riparian and wetland vegetation types developed for this guide were compared floristically and environmentally to riparian and wetland classifications in neighboring geographic regions. For each vegetation type, a section was included describing the occurrence(s) of the same or floristically similar vegetation types found in riparian and wetland classifications developed for neighboring geographic regions. Lastly, this guide was designed to be used in conjunction with the midmontane guide to provide a comprehensive look at the riparian and wetland vegetation of northeastern Oregon.

Download or read book Bunchgrass Plant Communities of the Blue and Ochoco Mountains written by Charles G. Johnson and published by . This book was released on 2005 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: A classification of bunchgrass vegetation is presented for the Malheur, Ochoco, Umatilla, and part of the Wallowa-Whitman National Forests. It includes grassland vegetation as well as shrubland and forest land where the herbaceous layer is dominated by bunchgrasses. It is based on potential vegetation, with the plant association as the basic unit. Diagnostic keys and descriptions are presented for each type. Descriptions include information about plant species occurrence, environment and soils, states and transitions, forage productivity, management considerations, and relationships to other classifications.

Download or read book Douglas Fir written by Stephen F. Arno and published by Mountaineers Books. This book was released on 2020-10-01 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Westerners familiar with their forests may think they know the Douglas fir--but how well do they? Douglas firs are found in the continental northwest from British Columbia to as far south as Oaxaca, Mexico. They flourish in the Cascades, Rocky Mountains, Sierra, and other mountain ranges, as well as in desert valleys. Incredibly hardy, this tree adopts various strategies to occupy more kinds of habitats than any other native tree, even becoming an uncontrollable invader in some regions, crowding out ponderosa pines, western larch, aspen groves, and mountain grasslands. Yet the utility of this noble species is immense. Douglas firs yield more high-quality construction lumber than any other tree in the world. Most intriguing of all, perhaps, is that the story of the Douglas fir has gone untold. Douglas Fir fills this literary gap and presents an engaging profile of the Douglas fir and its relationship to people, commerce, culture, and wilderness.

Book excerpt: "This guidebook describes Forest Creeks Research Natural Area, a 164-ha (405-ac) area comprising two geographically distinct canyons and associated drainages. The two units have been established as examples of first- to third-order streams originating within a ponderosa pine (Pinus ponderosa) zone. The two riparian areas also represent examples of the mountain alder-redosier dogwood (Alnus incana-Cornus sericea ssp. sericea), and the redosier dogwood-mockorange (Cornus sericea ssp. sericea-Philadelphus lewisii) plant associations." --

Download or read book Green Fescue Rangelands written by Charles G. Johnson and published by . This book was released on 2003 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication documents over 90 years of plant succession on green fescue grasslands in the subalpine ecological zone of the Wallowa Mountains in northeast Oregon. It also ties together the work of four scientists over a 60-year period. Arthur Sampson initiated his study of deteriorated rangeland in 1907. Elbert H. Reid began his studies of overgrazing in 1938. Both of these individuals utilized high-elevation green fescue grasslands in different locations in the Wallowa Mountains for their study areas. Then in 1956, Gerald Strickler returned to the sites previously studied by Sampson and Reid to establish the first permanent monitoring points when he located and staked camera points they had used. He also established line transects where he photographed and sampled the vegetation to benchmark the condition of the sites. In 1998, on the 60th anniversary of the Reid camera points in Tenderfoot Basin, the author returned to document the changes in the vegetation on the Sampson and Reid sites establishing photographic comparisons and resampling the transects Strickler had established. When Sampson and Reid conducted their initial studies, domestic sheep had overgrazed the vegetation leading to severely eroded soils and weakened native vegetation. In recent years, the presence of domestic sheep had declined dramatically. As a result, vegetation trends were generally found to be static or upward on most of the sampled sites. The recent drought period (1985-92) and the high population of elk in the 1980s and 1990s contributed to the downward trend on some permanent monitoring sites. The use of repeat photography from permanent camera points and the use of permanent line transects for vegetation data acquisition provide the basis on which this comparative study and publication of findings was made possible.
