The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...
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...
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...
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,
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....
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....
