Incidence of root pathogens on Douglas-fir within the Reuben's Reserve, Nez Perce Indian Reservation, Idaho

Creator:: James, Robert L. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Root diseases were evaluated on the Reuben's Reserve, Nez Perce Indian Reservation, Idaho. Nineteen trees adjacent to two suspected root disease centers were pushed with a D-6 tractor to expose their root systems. Extent of root necrosis and decay was determined and related to level of crown thinning, chlorosis, and...

Douglas-fir tussock moth adult male survey north Idaho and western Montana, 1982

Creator:: Dewey, Jerald E., Livingston, R. Ladd, Kohler, Steve, and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Douglas-fir tussock moth populations are monitored annually in northern Idaho and western Montana to insure early detection of changes from endemic to outbreak population levels. Adult moth trapping in 1982 was intensified and expanded into additional areas from 1981 because of concern that with each passing year the probability of...

Suppression of cranberry girdler damage in beds of Douglas-fir seedlings, Coeur d'Alene Nursery, Idaho Panhandle National Forest, 1984

Creator:: Tunnock, Scott and United States. Forest Service. Northern Region
Abstract:: The cranberry girdler, Chrysoteuchia toparia Zeller, has caused increasing damage to tree seedlings in the Coeur d'Alene Nursery since 1980. Heaviest feeding has occurred on the tap roots of 2+0 Douglas-fir stock. By 1983, 8.2 percent of the seedlings examined in seedbeds were injured by this moth. A spray program...

Evaluation of a proposed dwarf mistletoe project, Stevensville Ranger District, Bitterroot National Forest, Montana

Creator:: Dooling, Oscar J., Wiegand, Robert, and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Residual Douglas-fir and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning of dense patches of regeneration, will reduce dwarf mistletoe intensity and increase future volume yields. Present net worth of the project is $0.50/acre. Benefit/cost ratio is 1.01/1....

Monitoring root disease mortality : establishment report

Creator:: Hagle, Susan K. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Two thousand and thirty-nine trees on 213 plots are being monitored yearly for root disease infection and mortality. Three compartments on the Fernan Ranger District of the Idaho Panhandle National Forests are the site of the project. Relationships between factors such as species, aspect, slope, elevation, habitat type, stand appearance...

Insects associated with black stain root disease of Douglas-fir in western Oregon

Creator:: Witcosky, Jeffrey John
Abstract:: The root systems of Douglas-fir trees infected with Verticicladiella wagenerii and assigned by crown color and terminal growth characteristics to several stages of decline were excavated at three widely separated sites in the Coast Range of Oregon. Data were gathered on insect species present, extent of colonization of the root...

Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...
