The goal of this project is to recommend a broadly-acceptale efficient and effective methodology for characterizing streamside riparian attributes in forested settings at the site grain for regional monitoring. The authors consider monitoring design in the context of three interacting constraints: ecological functions, capabilities of technologies, and user needs. The...

These four items document the 2010-2011 permitting process to stabilize the eastern edge of the Hatfield Marine Science Center property. During late 2006, erosion forced the closure of the HMSC public estuary trail. In March 2007, an erosion control project using a gravel beach or "dynamic revetment" resulted in the...
Artificial substrates colonized by diatoms from Yaquina Estuary, Oregon, were exposed to solar visible radiation and three levels of ultraviolet radiation (UV-B, 290-320 nm). Flow-through microcosms were constructed inside a glasshouse to serve as chambers for the artificial substrates. The artificial substrates were sampled during three spring/summer experiments. Chlorophyll a...
Aerial photography taken of waste plumes from Kraft pulp mill ocean outfalls was shown to be an effective tool in the study of waste disposal sites. This technique is not limited by sea conditions and permits monitoring and evaluation of outfall sites throughout the year. Photography taken at one instant...
Ecologically sound practices often cost landowners more than less environmentally friendly tactics. However, some consumers are willing to pay more for the assurance of production practices they value. Third-party certification is a way to acknowledge sustainable production practices beyond what is required by law.
The market for such products is...
