Only recently have efforts begun to address how management might prepare currently healthy forests to affect the outcome of invasion by established non-native pests. Cronartium ribicola, the fungus that causes the disease white pine blister rust (WPBR), is among the introductions into North America where containment and eradication have failed; the disease(More)
Rocky Mountain bristlecone pine (Pinus aristata Engelm) and limber pine (Pinus flexilis James) are important high-elevation five-needle pines of the southern Rocky Mountains. At present, both species—and the biological communities they form—are forecast to decline extensively due to the recent and rapid spread of white pine blister rust (Cronartium ribicola(More)
Objective: Our purpose was to characterize vegetation compositional patterns, tree regeneration, and plant diversity, and their relationships to landscape context, topography, and light availability across the margins of four stand-replacing subalpine burns. Methods: Vegetation and environmental factors were sampled in 200 0.01-ha plots on transects(More)
Linkage of DNA markers with phenotypic traits provides essential information to dissect clustered genes with potential phenotypic contributions in a target genome region. Pinus flexilis E. James (limber pine) is a keystone five-needle pine species in mountain-top ecosystems of North America. White pine blister rust (WPBR), caused by a non-native fungal(More)
Increasing the frequency of resistance to the non-native fungus Cronartium ribicola (causative agent of white pine blister rust, WPBR) in limber pine populations is a primary management objective to sustain high-elevation forest communities. However, it is not known to what extent genetic disease resistance is costly to plant growth or carbon economy. In(More)
High-elevation, five-needle white pines are among the most picturesque trees in many national parks as well as other federal, state, and private lands in western North America. These trees often live to a great age; the trees' gnarled trunks give testimony to fierce winds that buffet them on exposed rocky sites. Ancient limber pines (Pinus flexilis) in(More)

White pine blister rust is now a permanent resident of North America. The disease continued to cause tree mortality and impact ecosystems in many areas. However, not all high elevation white pine ecosystems have been invaded; the pathogen is still spreading within the distributions of the whitebark, limber, foxtail, Rocky Mountain bristlecone pine and has(More)
Extended Abstract All nine species of white pines (five-needle pines) native to the United States are highly susceptible to Cronartium ribicola, the fungus causing white pine blister rust. The presence of genetic resistance will be the key to maintaining or restoring white pines in many ecosystems and planning gene conservation activities. Operational(More)
