Since 1984, the city of Cannon Beach has used a 7 ha, two-cell red
alder/twinberry/slough sedge palustrine wetland to treat chlorinated

In this work software is developed to take an ecosystem management tool used by the US Forest Service, the Ecosystem Management Decision Support (EMDS) system, and enhance its utility by capturing the results of an ecosystem assessment and saving them in a format that facilitates importation into other management tools,...
The Corvallis "urban area" has been selected for the

Across the U.S. there are tens of thousands of quarries and sand and gravel pits, the majority of which are left abandoned or with minimal reclamation efforts....
The western United States is experiencing significant changes in wildfire and snow regimes as a result of warming temperatures. An amplification of wildfire activity and reduction in snow water equivalent, snow covered area, and earlier spring snowmelt are documented trends that are projected to continue into the future. With an...
