Effects of pre-sowing soil treatments on root colonization of 1-0 ponderosa and lodgepole pine seedlings by potentially-pathogenic fungi, USDA Forest Service Lucky Peak Nursery, Boise, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Healthy-appearing 1-0 ponderosa and lodgepole pine seedlings were assayed for root infection and colonization by potentially-pathogenic fungi following pre-sowing soil treatments which included methyl bromide/chloropicrin (MBC) fumigation, fallowing with or/without periodic cultivation, and amending soil with mushroom composts or undecomposed sawdust. Levels of root colonization by Fusarium spp. on both...

Prescribed fire in a ponderosa pine stand in the Blue Mountains, Oregon : relationships among post-fire scolytidae incidence, delayed tree mortality, snag decay dynamics, and woodpecker snag use

Creator:: Kangas, Michael
Abstract:: Delayed tree mortality is an unpredictable occurrence when prescribed burning is implemented. Fire scorched trees may die as the result of crown scorching, stem charring, root injury, bark beetle attack, or through a combination of these factors. This study examined ponderosa pine mortality and the incidence of two bark beetle...

Diseases associated with whitebark pine seedling production, USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., Burr, K. E., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Whitebark pine is an important reforestation species in the northern Rocky Mountains for enhancement of wildlife habitat. Production of container-grown whitebark pine seedlings at the USDA Forest Service Nursery in Coeur d'Alene, Idaho has been increasing the past several years. Diseases continue to be an important limiting factor in seedling...

Climate-growth relationships of western juniper and ponderosa pine at the pine-woodland ecotone in southern Oregon

Creator:: Knutson, Kevin C.
Abstract:: Pinyon-juniper woodlands throughout the western U.S. have expanded rapidly following European settlement during the late 19th century. In central and eastern Oregon, western juniper (Juniperus occidentalis var. occidentalis Hook.) encroachment has been previously documented in the sagebrush steppe and upper elevation aspen communities. While these vegetation changes and dynamics have...

Field classification of white pine blister rust stem-cankers on resistant western white pine in northern Idaho and determination of respective tissue damage through tree ring analysis

Creator:: Eckert, Amy I.
Abstract:: Western white pine historically dominated northern Idaho’s forested landscape and was the Inland Empire’s most economically important tree. White pine blister rust, caused by the exotic fungus Cronartium ribicola, played a principal role in the decline of western white pine. The pathogen causes branch and bole cankers, which usually girdle...

Effects of preplant soil treatments on Fusarium and Trichoderma populations and fungal root colonization of 2-0 nondiseased western white pine seedlings - USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Preplant soil treatments were implemented to determine effects on populations of potentiallypathogenic Fusarium and potentially disease-suppressive Trichoderma spp. as well as root colonization by these and other selected fungi on healthy-appearing, bare root 2-0 western white pine seedlings at the USDA Forest Service Nursery, Coeur d'Alene, Idaho. Soil treatments included...

Effects of spring applications of dazomet on root diseases and performance of Douglas-fir and western white pine transplants, USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L., United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Tests were conducted at the USDA Forest Service Nursery, Coeur d'Alene, Idaho to evaluate effectiveness of spring fumigation with dazomet to improve survival and performance of Douglas-fir and western white pine transplants. Spring fumigation greatly reduced populations of potentially pathogenic Fusarium and Pythium spp. Disease levels of container (plug+1) and...

Cone and seed insects and their impact on whitebark pine

Creator:: Kegley, Sandy, United States. Forest Health Protection, and United States. Forest Service. Northern Region
Abstract:: Whitebark pine, Pinus albicaulis Engelm. is an important but declining high-elevation tree species in western forests. Regeneration of this species has been difficult and the impact of cone and seed insects unknown. Seven sites selected from the geographical range of whitebark pine in Idaho, Montana, Washington, Oregon, and California were...
