Four formations of the Cretaceous Nanaimo Group crop out on Galiano Island and on Parker and Gossip Islands, nearby. These formations are: early Campanian Geoffrey Formation which encloses a tongue of the Northumberland Formation; early Campanian to late Maestrichtian Spray Formation; and Maestrichtian Gabriola Formation. The stratigraphic succession has a...
A microclimatology study was conducted on a high elevation clearcut
near the summit of Mt. Ashland in southwest Oregon to evaluate the effects
of frost on Douglas-fir seedling growth and survival. Frost and low
temperatures cause seedling stress through frost damage, frost desiccation,
increased root resistance, and decreased rates of...
Carter Lake, a freshwater, coastal dune-margin lake,
was sampled at the beginning and end of the summer of 1986
to determine the sediment characteristics and benthic
macroinvertebrate abundance, biomass, variety, and
diversity. The distributions of major benthic habitats were
estimated by snorkeling in June and July, 1986. Water
temperature and...
Part of the responsibility of maintaining the sanitary quality
of individual water supply systems has been placed on the local sanitarian
of Oregon. Because of this, he must be knowledgeable about
individual water supply systems. One such source of knowledge has
been the supply of written reference materials available in...
The relationship between population and residential property taxes
is not well understood. This study is an attempt to discern the relationship.
The basic questions examined are: How does population affect tax
bills? What are the short-run and long-run relationships between population and taxes? What reasons lie behind the answers to...
Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...
