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...
After 14 years, chloropicrin, Vapam and Vorlex continue to effectively
control internal decay of pressure-treated Douglas-fir
transmission poles, but 6 years after application of methylisothiocyanate
(MIT) some poles are becoming reinfested by decay fungi
although NIT residues remain high in these poles. The closed-tube
bioassay, developed through our research, is...
This fifth annual Cooperative Pole Research Program report
outlines our progress in the six project objectives.
Improved Fumigants
Sampling of previously established field tests revealed that
Vorlex and Chloropicrin continued to perform well after 15 years,
while Vapam was slightly less effective. Solid methylisothiocyanate
(MIT) also performed well in the...
ABSTRACT
Improved Fumigants
Chioropicrin, Vorlex and Vapam continue to control internal decay of
pressure-treated Douglas-fir poles 12 years after application. Fungitoxic quantities
of chloropicrin are present in the wood as high as 2.4 m (8 feet) above
the groundline. Solid methylisothiocyanate (MIT), which goes directly to a vapor,
is somewhat...
ABSTRACT
Fumigants. Chioropicrin, Vapam and Vorlex continue to control Internal
decay of Douglas-fir poles 11 years after application.
Methylisothiocyanate (MIT), which was melted and poured into holes in
Douglas-fir poles 3-years ago and goes directly from a solid to a gas in the
wood, appears promising In controlling decay fungi....
ABSTRACT
Improved Fumigants
After 13 years, chioropicrin, methylisothiocyanate (MIT), Vapam, and
Vorlex continue to effectively control internal decay of pressure-treated
Douglas-fir transmission poles. The estimated retreating schedules for
application of these fumigants to treated wood may be as long as 10 years
for Vapam and 15 years for the others....
Salmon recovery requires restoration of spawning habitat to improve egg-to-smolt survival. Private lands play a crucial role. Funds for restoration are available from both federal appropriations and legal settlements for dam mitigation. Federal agencies responsible for recovery are often limited in their ability to work on private lands however, not...
A multidisciplinary team of scientists (Appendix 1) examined 10 of the 16 environmental benchmarks that are tracked by the Oregon Progress Board. The intent of the environmental benchmarks is to provide a fair assessment of the status and trends of Oregon's environmental health. The scientists were asked to clarify benchmark...
This dataset was digitized from a list of waterways identified by the Oregon Parks and Recreation Department as "state scenic waterways" in accordance with the Scenic Waterways Act.

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...
