Observations on the impact of western spruce budworm on the Nezperce National Forest, Idaho, 1972

Creator:: Ciesla, William M., Lood, Rudolph C., Bousfield, Wayne E., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Aerial surveys of the Nezperce National Forest in Idaho revealed 138,692 acres of aerially visible top kill and tree mortality due to repeated defoliation by western spruce budworm, Choristoneura occidentalis Freeman. A small ground sample indicates that up to 47 percent of the grand fir volume was affected by top...

Forecasting western spruce budworm defoliation in mixed conifer stands by counting hibernating larvae

Creator:: Tunnock, Scott and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: An attempt was made in January 1971 to relate the numbers of hibernating western spruce budworm larvae on a square foot of bark surface with subsequent shoot damage on Douglas-fir and grand fir in northern Idaho. Twenty-six plots sampled in January were also sampled in April to determine if larval...

Root disease survey on the Nezperce National Forest, Idaho

Creator:: James, Robert L., Stewart, C. A., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: An impact survey to determine extent and distribution of root disease centers was completed for the Nezperce National Forest, Idaho, in 1980. Lowlevel color infrared photography was used to delineate root disease centers within National Forest inventory subcompartments. Suspected root disease centers were ground checked to determine associated fungi and...

Population structure and incidence of Heterobasidion annosum in grand fir and Douglas-fir on the Nez Perce National Forest, Idaho

Creator:: Lockman, Irene Blakey
Abstract:: Annosus root disease (Heterobasidion annosum (Fr.) Bref.) is causing notable conifer mortality in grand fir habitat types in central Idaho. The most significant mortality is occurring in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco.) trees of all age classes. This project was designed to study some aspects of the general biology of...

Ground application of dimethoate (Cygon) for the control of cone and seed destroying insects of Douglas-fir and grand fir

Creator:: Dewey, Jerald E., United States. Forest Service. Northern Region. Forest Environmental Protection, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Two concentrations of dimethoate were applied with a hydraulic ground sprayer to cone-bearing Douglas-fir and grand fir trees. Single application (mid-June) and a double application (mid-June and mid-July) were compared. Three of the four treatments applied to Douglas-fir resulted in a significantly higher number of sound seeds produced per cone...
