    Description

    As part of a larger effort to assess the distribution and ecology of Armillaria species throughout western North America, we present preliminary survey results for the East Cascades of Oregon. Surveys and sampling were conducted on 260 0.04-ha plots, which were randomly located across diverse environments and geographic locations. Using DNA-based techniques for the identification of Armillaria spp., we identified three genetically-distinct species groups that comprised the ca. 450+ Armillaria samples. The association of Armillaria species groups with habitat is summarized based on detailed vegetation data. When we understand habitats in which Armillaria species can potentially occur, forest management prescriptions can be developed to improve forest health at the stand level by reducing impacts of Armillaria root disease. These data also provide critical baseline information for evaluating larger-scale impacts in forest ecosystems as trees are subjected to climate-change induced stress.
