Hydrographic and optical measurements were made in situ in the Congo River and the Angola Basin during May 1978. These measurements were made by members of the optical oceanography group at Oregon State University in cooperation with scientists from the Netherlands Institute for Sea Research. The data taken by the...
Sixteen understory plant communities in the riparian zones of small streams are identified and described. They range from pioneer communities on gravel and rock to well-developed shrub communities on flood
plains and terraces. Several other vegetation types are discussed. Distribution of communities within the riparian zone is also discussed. A...
This three page report details a shark attack on a surfer that tooks place on November 27, 1979 off Cannon Beach, Oregon. The bite marks on the surfboard are detailed including x-rays showing the teeth marks.
This report is one of a series prepared by the Oregon Department of Fish
and Wildlife (ODFW) which summarizes the physical and biological data for
selected Oregon estuaries. The reports are intended to assist coastal planners
and resource managers in Oregon in fulfilling the inventory and comprehensive
plan requirements of...
1. Defoliation by cankerworms in 1979 was significantly less in 1978 treated shelterbelts than in untreated shelterbelts. 2. Most shelterbelts treated in 1978 retained enough foliage by late June 1979 so that adjacent crops were protected from wind. 3. Aerially applied Bt at a rate of 1/2 lb./acre provided shelterbelt...
During December 1978 and January 1979, temperatures reached all-time lows in some parts of Montana. Overwintering mountain pine beetle populations were sampled at 11 sites during February and March 1979. Effects of the extreme cold varied from site to site, with larval mortality ranging from 6 percent to 100 percent....
Mountain pine beetle populations developed to epidemic level in 1970 on the Hebgen Lake Ranger District. Infested acreage increased from 78,000 in 1977 to 79,061 in 1978. More than 4 million trees (238 MMBF) were killed in 1978. Cold temperatures during December 1978 may cause a significant decline in the...
Over the continental shelf at 15°S off Peru, sigma-t is a well-defined
function of temperature (Figure 1) and hence temperature alone may be used
to monitor the changes in stratification, to test the thermal wind equation,
and to monitor the hydrographic response to wind events. In this report we
present...
A multistage sampling survey to measure annual and cumulative mortality of lodgepole
pine by mountain pine beetle was conducted
on the Beaverhead and Gallatin National
Forests, 1978-79. The survey area, 270,000
acres, was stratified into three intensity classes
from aerial sketchmapping. This was followed
by large scale (1:6,000) aerial photography,...
CONIFER simulates water, carbon, and energy dynamics of a coniferous forest. The model consists of 29 nonlinear difference equations. Measured driving variables include air temperature, dew point temperature, precipitation, solar radiation, and wind speed. Water and energy variables are updated
daily; carbon variables are updated weekly. This report contains a...
We conducted a combination road/plot impact survey for dwarf mistletoe in lodgepole pine on six East Side National Forests in 1978. The road survey showed infestation percentages ranging from 28.2 on the Custer to 52.4 on the Beaverhead. The plot survey showed annual cubic foot volume losses ranging from 106M...
Based on per acre costs, plantation establishment is one of the most expensive silvicultural practices (Pfister 1976), but only token studies have been done on frequency and causes of seedling injury and mortality in Region 1 plantations (Wenner 1976). Therefore, we conducted a survey in 1978 on four National Forests...
The larch casebearer, Coleophora laricella (Hubner) was first reported attacking western larch, Larix occidentalis, in Idaho in 1957 (Denton, 1958), 71 years after its introduction into Massachusetts from Europe. The apparent successful regulation of this insect in the eastern U.S. by introduced parasites prompted biological control attempts in the West....
This report contains a brief history of selected mountain pine beetle infestations and the potential for infestations in high hazard stands on the Tally Lake Ranger District. Management alternatives to lessen the severity, or reduce the possibility, of infestations are discussed.
Preliminary analysis of data from this study in the mountains southwest of the Anaconda Copper Smelter, an industrial source of SO2 and heavy metal particulate, reflects a complex pattern of pollutant impact. The differential effect of smelter emissions on plant life in the study area is best explained by the...
This report contains an overview of the present mountain pine beetle infestation in lodgepole pine stands on Federal, State, and private lands on the Plains Ranger District. Particular emphasis is placed on the potential for beetle mortality in the Thompson River drainage where recent ground surveys show more than 21...
