Contains ground-truthed wetland maps and scores representing ecosystem services of a large portion of the wetlands in Juneau, Alaska. LiDAR imagery was used extensively.
The Juneau Wetland Management Plan (JWMP), Volume 1, provides results of wetlands mapping and wetland functional assessments for currently undeveloped parcels within the City and Borough of Juneau (CBJ). The study areas were selected for their potential for future development based on low elevation and proximity to existing infrastructure. During...
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...
Because studies of forestry effects on wetlands have been so infrequent in the Pacific Northwest, each section in this report drew heavily from studies of forestry impacts to streams and riparian zones. After assembly and synthesis, that information was extrapolated, mostly in the form of hypotheses, to the very different...
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...
This report documents vegetation monitoring and mapping conducted by Green Point Consulting during summer 2006 at six tidal wetland restoration and reference sites in the Siletz Bay National
Wildlife Refuge of Oregon, and the upper Yaquina River estuary (near Toledo, Oregon). Vegetation at all sites except one had been monitored...
The use of Landsat data has historically been constrained to spectral and spatial information derived from a carefully selected image or set of images. However, free and open access to Landsat imagery combined with advances in data storage and computing are revolutionizing how the Landsat temporal domain is used to...
This report is divided into several sections. The first provides information
on the current status of wetlands, the Corps' regulatory role, its statutory
enforcement authority, and its interpretation of that authority. The next
section describes the Portland District's enforcement structure and procedures.
A case study detailing the District's treatment of...
Despite holding substantial ecological value, wetlands in the United States have experienced a significant decline in both area and function over the past century with the majority of freshwater wetland loss attributed to agricultural conversion. Agriculture is the second largest industry in the State of Oregon and the State places...
Marsh, bog, swamp, slough, fen–these are just a few
of the names commonly applied to the class of
natural habitats called "wetlands." Broadly defined,
wetlands are land areas that have a prolonged high water
table or at least are covered with shallow water. As a transition
habitat between dry land...
