Reduction in growth of pole-sized Ponderosa pine related to a Pandora moth outbreak in central Oregon

Creator:: Cochran, P. H.
Abstract:: A pandora moth (Coloradia pandora Blake) outbreak began in 1991 in a ponderosa pine (Pinus ponderosa Dougl. ex. Laws) spacing study area that also included scattered sugar pine (P. lambertiana Dougl). The relation of defoliation to five tree spacings (with and without understory vegetation) was examined, and stand growth reduction...

Effects of environment and genetics on western pine shoot borer, Eucosma sonomana, infestation levels in ponderosa pine plantations of central Oregon

Creator:: Prueitt, Sara C.
Abstract:: Infestations of the western pine shoot borer (Eucosma sonomana Kearfott) in young stands of ponderosa pine (Pinusponderosa Lawson), were surveyed on the Deschutes National Forest. Elevation, slope, aspect, tree height, tree diameter, number of shoots in the terminal whorl, stand density, stand age and plant association for each stand were...

Pine butterfly (Neophasia menapia) outbreak in the Malheur National Forest, Blue Mountains, Oregon : examining patterns of defoliation

Creator:: DeMarco, Ariadne T.
Abstract:: The pine butterfly (Neophasia menapia C. Felder & R. Felder) (Lepidoptera: Pieridae) is a relatively host-specific defoliator of ponderosa pine (Pinus ponderosa Dougl. ex Laws). From 2008 to 2012, the Malheur National Forest was subject to an outbreak of pine butterfly in ponderosa pine, peaking at ~100,000 ha of forest...

Chemical applications for control of armillaria root rot of Ponderosa pine

Creator:: Filip, Gregory M.
Abstract:: Root rot caused by Armillariella mellea creates roughly circular disease centers of infected dead and dying trees in the younggrowth ponderosa pine forest under study. Research objectives concerning chemical control of the disease were: 1) to test the effectiveness of certain chemicals in protecting living pines adjacent to disease centers...

Infection of stressed ponderosa pines by Armillariella mellea from indigenous and artificial inoculum sources

Creator:: Fuller, Lloyd Randolph
Abstract:: Armillariella mellea (Vahl. ex Fr. ) Karst. was grown aseptically in hazel stems (Corylus cornuta var. californica) which were used in the forest to infect 290 ponderosa pines (Pinus ponderosa Laws.) which had been "stressed" in five different manners plus two control groups. All trees were inoculated twice giving a...

Stress response as a basis for disease susceptibility in Ponderosa Pine

Creator:: Koonce, Andrea
Abstract:: Trees stressed by artificial and natural means were sampled for response in growth and vigor, carbohydrate content, resin pressure characteristics, and water relations. Tree response was found to reflect both the severity and type of stress imposed. Crown color and appearance were reliable indicators of prolonged stress and advanced decline...

Anatomical studies of Pinus ponderosa Laws : infested by Elytroderma deformans (Weir) Darker

Creator:: Wirtz, Felicia Pietrykowski
Abstract:: Pine needle blight of Pinus ponderosa Laws. caused by Elytroderma deformans (Weir) Darker is recognized by changes in the needles, in the bark and in the development of the branches. Anatomical studies of the host-parasite relation have been made previously on young pine tissue up to four years of age...
