Effects of Phellinus weirii on plant community composition and succession of mature and old-growth Douglas-fir forests

Creator:: Holah, Jennifer C.
Abstract:: Disease is often overlooked as a natural disturbance agent in plant communities. This study examines what effects, if any, a disease-mediated disturbance has on the plant community as a whole in old-growth and mature forests of western Oregon. Phellinus weirii (Murrill) Gilbertson (Family: Hymenochaetaceae) is a native root-rotting pathogen that...

Taper, crown, and volume responses of a coastal Oregon Douglas-fir stand to sulfur treatments for control of Swiss needle cast

Creator:: Younger, Nicole L.
Abstract:: For nearly two decades, foresters in the Oregon Coast Range have been witnessing a substantial decease in Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) vigor and growth, caused by Swiss needle cast (Phaeocryptopus gaeumannii). Currently, no solutions are in sight but aerially-applied sulfur may alleviate Swiss needle cast and its...

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...

Potential Douglas-fir tussock moth damage in northern Idaho in 1974 based on a 1973 fall egg mass survey

Creator:: Tunnock, Scott and Livingston, R. Ladd
Abstract:: An epidemic of Douglas-fir tussock moth was detected in northern Idaho in 1972. In 1973, aerial surveys showed that nearly 100,000 acres contained various degrees of visible defoliation. An egg mass survey of five reporting units made in the fall of 1973 determined potential for damage in 1974. Based on...

Tree vigor and the susceptibility of Douglas-fir to armillaria root disease

Creator:: Rosso, Pablo H.
Abstract:: The main objective of this thesis was to determine the influence of tree vigor on susceptibility to Armillaria root disease. First, the effect of thinning, fertilizing and pruning on tree vigor of four young Douglas-fir (Pseudo tsuga menziesii var. menziesi,) plantations was explored. Tree vigor was calculated by measuring wood...
