A historical reconstruction and land use history of six tidal wetlands in Oregon

Creator:: Hennessey, Jennifer T.
Abstract:: This Master's Degree project is intended to document historical ecological conditions and land use histories during the past 150 years for selected Oregon watersheds and tidal wetland sites. The sites are the subject of current research into the ability of tidal wetlands to provide rearing habitat and prey for juvenile...

Evaluating design and verifying compliance of wetlands created under section 404 of the Clean Water Act in Oregon

Creator:: Gwin, Stephanie E. and Kentula, Mary E.
Abstract:: Permit specifications, construction plans, and field measurements were used to examine the correlation between design and conditions "as-built" in a population of 11 palustrine emergent marshes created in the metropolitan area of Portland, Oregon, between 1980-1986. The projects ranged from six months to almost seven years in age. Data on...

Hydrologic and vegetation responses associated with restoration of wetlands in the Willamette Valley, Oregon

Creator:: Coleman, Gregory A.
Abstract:: I examined hydrological and plant community changes associated with the implementation of a restoration management plan in two riparian meadows located within an agricultural landscape of the central Willamette Valley, Oregon. I established exclosure fencing (a form of passive restoration) in one agricultural field and established fencing and plugged a...

Value assessment of Jackson-Frazier Wetland, Benton County, Oregon : a case study

Creator:: Marshall, John L. (John Lee), 1952-
Abstract:: A growing realization that wetlands are potentially valuable resources has recently stimulated efforts towards their protection. While a foundation for wetland management exists, decision makers still lack adequate tools for addressing issues of wetland preservation vs. development. Wetland preservation values are often neglected in traditional market analyses and in the...

Hydrology and delineation in four wetlands in the Oregon Cascades

Creator:: MacLeod, Norman A.
Abstract:: Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

The stratigraphy, hydrology, and redoximorphic character of the Jackson-Frazier wetland

Creator:: D'Amore, David V.
Abstract:: Transitional areas between upland and aquatic habitats, commonly known as wetland, were once viewed as unproductive areas and were drained for farming or pasture. Wetlands are now accepted as significant ecological resources, and their protection is a mandate of federal, state, and local land managers. Due to the diversity of...

Plant community dynamics in remnant and restored Willamette Valley wetland prairies

Creator:: Schwindt, Rachel A.
Abstract:: Invasion by exotic species can pose a major challenge for developing native plant communities in wetland restoration projects. Often native plant communities do not develop as anticipated in restored wetlands due to colonization by exotic species that dominate the native plant community. Despite the time and expense to restore wetlands,...
