Modeling Blister Rust Incidence in Whitebark Pine at Northern Rocky Mountain Alpine Treelines: A Geospatial Approach
… (Cronartium ribicola) that causes white pine blister rust in five-needled pines. Originally thought to be limited to moderate environments, the disease is now found extensively throughout colder and dryer regions east of the Continental Divide, including alpine treeline. My research objective …

Landscape pattern and blister rust infection in whitebark pine (Pinus albicaulis) at alpine treeline, Northern Rocky Mountains, U.S.A.
… and is threatened by the fungus white pine blister rust (Cronartium ribicola). This disease affects all five-needled white pines, but has caused particularly widespread mortality in whitebark pine. Objectives of this research were: 1) to characterize the landscape structure of the treeline …

Ecological Process and the Blister Rust Epidemic: Cone Production, Cone Predation, and Seed Dispersal in Whitebark Pine (Pinus albicaulis)
… fungal pathogen, Cronartium ribicola (white pine blister rust), infects whitebark pine and kills cone-bearing branches and trees. Blister rust has spread nearly rangewide and damage and mortality are highest in the northwest US and southwest Canada. Mortality caused by mountain pine beetle …

Geospatial Variation of an Invasive Forest Disease and the Effects on Treeline Dynamics in the Rocky Mountains
… treelines. The manifestation of white pine blister rust in the cold and dry treelines of the Rockies, and the subsequent infection and mortality of whitebark pines raises questions as to how these extreme environments harbor the invasive disease, and what the consequences may be for treeline …

Mountain pine beetle outbreaks in high elevation whitebark pine forests: the effects of tree host species and blister rust infection severity on beetle productivity
… ribicola, which causes the disease white pine blister rust (WPBR). This study examines MPB productivity in whitebark pine compared to that in lodgepole pine, and also in whitebark pine of varying WPBR infection severities to determine if either of these host factors contributes to the current, …

Time series analysis of limber pine (Pinus flexilis) health in the U.S. Rocky Mountains in response to white pine blister rust (Cronartium ribicola) and bark beetles
… health trends in response to white pine blister rust (WPBR) and bark beetles (including mountain pine beetle, "MPB", and Ips spp., "Ips") over time. These plots were subsequently measured in 2011-2013 and again in 2016-17 to form a time series analysis of limber pine health. Data were …

Population Structure and Biophysical Density Correlates of Whitebark Pine (Pinus albicaulis) at Two Treelines in the Northern Rocky Mountains
… in the northern Rocky Mountains is white pine blister rust, caused by the exotic fungal pathogen Cronartium ribicola. In this study, I aim to: 1) assess population structure and regeneration within two geographically different treelines experiencing contrasting levels of infection, and 2) …

ASSESSMENT OF WHITEBARK PINE SEEDLING SURVIVAL FOR ROCKY MOUNTAIN PLANTINGS
… pervasive non-native fungal disease (white pine blister rust), mountain pine beetle infestation, and successional replacement by shade-tolerant competitors following decades of fire exclusion have severely reduced whitebark pine and threaten these high-elevation ecosystems. Land managers are …

Restoration planting options for Pinus flexilis James in the southern Rocky Mountains
… impacts of mountain pine beetles and white pine blister rust. P. flexilis' critical role in high elevation ecosystems heightens the importance of mitigating threats to P. flexilis survival. To develop forest-scale planting methods, six P. flexilis seedling planting trial sites were installed, …

The growth and productivity of ribes nigrum under various levels of shade and the implications for multifunctional woody polycultures
… as it was an alternate host to the white pine blister rust (Cronartium ribicola J.C Fisch In Rabh.), which caused extensive damage to the white pine (Pinus strobus) lumber industry. Upon legalization in the latter half of the 20th century, black currants have been making a slow comeback. The …
