Wetlands of the Colorado Plateau that receive water from irrigation can, by their functions, support several societal values. For example, their capacity for removing nitrate and perhaps pesticides from nonpoint source runoff might be considerable. However, relatively little research has been conducted in irrigated wetlands, and their ability to alter...
It can be reasonably assumed that lamprey eel harvesting has systematically and periodically occurred along the Siletz River and its tributaries for as many hundreds, or thousands, or tens of thousands of years that human families and lamprey eel populations have coexisted in the Siletz Valley ecosystem. This report is...
Surveys of flora and fauna were conducted in riparian areas of six streams in the general vicinity of the Iron Mountain mine near Redding, California. The surveys were intended to provide part of the information needed for a natural resource damage assessment (NRDA), should such an assessment be desired at...
Potentially relevant literature for the years 1990-1999 was identified by (a) conducting keyword searches of computerized bibliographic databases, especially CAB Abstracts and Aquatic Sciences and Fisheries Abstracts, (b) reading through the tables of contents of a few especially relevant journals, (c) searching the internet for pertinent bibliographies, and (d) to...
This report and especially the accompanying Detail Files and MapFiles provide relatively detailed information on status, trends, distribution, limiting factors, and conservation needs of all of the Willamette’s wildlife species, listed plants, and vulnerable habitats. Data on habitat suitability for each species is provided by watershed (170 HUC6s), elevation (6...
This document is primarily a review of Best Available Science applicable to Island County wetlands, as needed for categorizing wetlands for regulatory actions and determining widths for buffers (setbacks) that protect the functions of wetlands. The number of technical papers and reports published on these topics is enormous, and none...
This report is intended to provide a foundation for eventually developing one module of the Michigan Rapid Assessment Method (MiRAM). Specifically, it provides information on specific attributes of wetlands that can be used, along with information on species ranges, to help predict the assemblage of wildlife species most likely to...
Working waterfronts across the nation are under pressure. Land use priorities of local governments are changing in response to population growth, new economic pressures, and shifting policy and politics. In Oregon, the decline of fisheries and timber in economic importance followed by the growth of tourism and retirement services has...
The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence....
In a series of Willamette Valley wetlands, standardized protocols were used in 2009 and 2010 to primarily assess (a) vegetation species composition and (b) relative levels of ecosystem services. Of the 60 wetlands visited in one or both years, 34 were classified as riverine and 26 as flats. Of the...
