This report summarizes accomplishments of the McKenzie River Focus Watershed Council (MWC) in the areas of coordination and administration during Fiscal Year 2000. Coordination and administration consist of prioritization and planning for projects; project management and implementation; procurement of funding for long-term support of the Council; and watershed education/outreach program...
Water quality changes along hyporheic flow paths may have important effects on river water quality and aquatic habitat. Previous studies on the Williamette River, Oregon, showed that river water follows hyporheic flow paths through highly porous deposits created by river channel meandering. To determine water quality changes associated with hyporheic...
This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused...
The scientific literature on logging after wildfire is reviewed, with a focus on environmental effects of logging and removal of large woody structure. Rehabilitation, the practice of planting or seeding after logging, is not reviewed here. Several publications are cited that can be described as 'commentaries', intended to help frame...
This publication is aimed at watershed councils, government agencies, and specialists (foresters, wildlife and fisheries biologists) interested in riparian area silviculture or watershed restoration. It contains information on the ecology of riparian forests and a checklist of recommended practices and common mistakes made in restoring conifers to hardwood-dominated riparian forests....
By the early 1990s, the citizens of Tillamook County recognized that environmental problems facing Tillamook Bay threatened the very future of those residing here. Declining fish runs meant loss of income for commercial fishermen, tackle shops, hotel owners, and other fishing - dependent businesses. Decreasing water quality meant violations of...
For the past ten years, Douglas-fir on the Oregon and Washington coast has shown a progressive decrease in height and diameter increment as a result of Swiss needle cast, which is caused by Phaeocryptopus gaeumannii. In this contribution, we discuss the effects of silvicultural operations on Swiss needle cast and...
This report documents oceanographic and meteorological measurements made from instruments deployed on four moorings over the continental shelf west of Oregon, from spring through
summer, 1999. These moorings were a component of an observational and numerical modeling program to study the response of the coastal ocean to wind forcing.
The...
The purpose of this research is two-fold: to evaluate the success of the new emergency procedures promulgated in 1998 and to characterize the erosion event that precipitated the emergency during January, February and March 1999. These two purposes support each other and provide a holistic understanding of how emergencies arise...
Since their discovery in 1977, hydrothermal vent communities have offered scientists
a unique glimpse into a world that is supported primarily by chemically derived
energy rather than direct energy from the sun. Furthermore, studies of hydrothermal
vent ecosystems have introduced scientists to amazing animals that have successfully
adapted to living...
Equations for predicting height to crown base are presented for tree species from southwest Oregon. Equations for undamaged and damaged trees were estimated with weighted nonlinear regression techniques. The effects of specific damaging agents on the height to crown base were explored, and damage correction factors were estimated. The damage...
The 14-km long Netarts Littoral Cell, located on the northern Oregon coast, experienced episodic erosion as a result of the severe 1997-98 El Nino and 1998-99 La Nina. The erosion events led to the development of a unique partnership bridging scientists, stakeholders, and various planning agencies. To address these erosion...
In spring time, animals, goats and sheep in particular, prefer to eat flowers Pulsatilla multifida, and Iris tenifolia. Pulsatilla's flower contains sugar 20.33, starch 6.71, cellulose 19.15, lignin 6.50, and acid detergent fibre (ADF) 24.88, neutral detergent fibre (NDF) 32.55, hemicellulose 7.67, and protein 14.27 percent. Dry matter digestibility (DMD),...
Vegetation and geographic region including forest steppe in Khangai Range, mountain steppe in Mongol Altai, desert steppe in the Great Lakes Depression, the Valley of the Lakes and Gobi Altai Mountains and Zuungar and Trans-Altai Gobi were covered by the scope of the investigation. 181 samples of 123 plant species...

Desert, desert-steppe (Gobi) zone is the largest province by area (165,000 square kilometres) of Mongolia. The Gobi contains some 560 plant species, in 80 different vegetation associations (Swift, 1991). There are number of results of nutritive value of desert-steppe’s pasture grass. Mongolia’s dry climate means that pasture grasses have less...
In its quest to promote the wise utilization and conservation of the United States' ocean and coastal resources, the National Sea Grant Program sponsors a vast array of research and educational ventures. Much of this is published, either in print or electronically. Locating this information can be an adventure even...
The goal of the Oregon Plan is to restore wild coho and wild steelhead runs. Under the federal Endangered Species Act, wild coho salmon along the Oregon Coast are listed as Threatened and wild Oregon Coast steelhead are a candidate for listing. Although cormorants have been hazed at the Nehalem...
Much of the native riparian vegetation of the Willamette Valley, Oregon, has been replaced with agricultural crops or invasive non-native plant species. Detailed information about current Willamette Valley riparian vegetation is generally lacking. Plant specie composition data are useful in a variety of applications, including condition assessment, environmental monitoring and...
