Book Subalpine Wetlands

Download or read book Subalpine Wetlands written by Sunni Marie Heikes-Knapton and published by . This book was released on 2009 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subalpine region throughout the western US is increasingly pressured by land use changes. Consequences of these changes often involve major alteration to the original function of the landscape, particularly concerning wetland and riparian areas. In southwest Montana, large developments have recently been created or expanded in the subalpine environment. Wetlands in these regions bear a particularly unique structure, and often are influenced by the effects of development. The alteration to structure can result in disturbance to the original hydrological, ecological, and biogeochemical functions of wetlands. Restoration efforts attempt to mitigate for development influences, but the monitoring and success criteria do not wholly address the functional attributes of these features. At the same time, little is known about the structure of undisturbed subalpine wetlands and how environmental drivers influence the undisturbed structure and hydrological, ecological, and biogeochemical functions. Knowledge of these natural processes is necessary to ensure appropriate management decisions and future restoration success. This study examines small subalpine wetlands in an elevation range of 2256-2316 m located in southwest Montana. Study sites include two wetland types, in undisturbed and restored conditions. This research examines physical, chemical, biological, and hydrological attributes of wetlands in varying conditions, to define and compare wetland characteristics, determine primary environmental drivers of wetland ecological and biogeochemical functions, and compare response to human perturbation. Comparisons of our data indicate significant differences in all categories of parameters, and include metrics of biodiversity, primary productivity, hydrologic regime, and physical and chemical properties of the soil. Several environmental drivers are identified, with the primary driver of vegetation and redox response variables being depth to water and persistence of saturated conditions. The depressional wetland type is characterized by a distinct hydrologic regime, with these conditions being significantly related to a greater number of ecological and biogeochemical functions than the linear wetland type. Restoration data indicate that the restoration methods employed are sufficient in establishing the primary wetland characteristics used in wetland definition. However, the trajectory of restored wetlands indicates that long term recovery may result in wetlands exhibiting different structural and functional attributes than intended.

Book An Ecological Characterization of Rocky Mountain Montane and Subalpine Wetlands

Download or read book An Ecological Characterization of Rocky Mountain Montane and Subalpine Wetlands written by and published by . This book was released on 1986 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document has been prepared to provide a comprehensive review of Rocky Mountain wetlands. It draws on all types and sources of scientific information and is both an analysis and synthesis. We recognized from the outset that large gaps exist in the scientific literature on Rocky Mountain wetlands. An attempt has been made to identify and delineate these gaps in order to estimate the magnitude of research needed to narrow them. Therefore, this document is both a state-of-the-art and state-of-the-science of Rocky Mountain wetlands as of December 1985. This report is intended to provide information for the assessment, planning, and permitting activities of Federal and State agencies. It is also an educational source document for anyone interested in the ecological functioning and value of high-elevation wetlands.

Book Deep Canyon and Subalpine Riparian and Wetland Plant Associations of the Malheur Umatilla and Wallowa Whitman National Forests

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.

Book Invertebrates in Freshwater Wetlands of North America

Download or read book Invertebrates in Freshwater Wetlands of North America written by Darold P. Batzer and published by John Wiley & Sons. This book was released on 1999-03-15 with total page 1122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are crucial ecosystems that help filter a great number of toxicants out of the earth's waters. They must be managed and occasionally even built from scratch, including all of the flora and fauna that grows there. Invertebrates play a key role in the wetland food chain. This comprehensive resource is the first dedicated solely to the ecology and management of invertebrates.
