Survey of Armillaria spp. in the Oregon East Cascades: Baseline data for predicting climatic influences on Armillaria root disease


Hanna, J. W.; Smith, A. L.; Maffei, H. M.; Kim, M.-S.; Klopfenstein, N. B. 2008. Survey of Armillaria spp. in the Oregon East Cascades: Baseline data for predicting climatic influences on Armillaria root disease. In: Baker, F.; Jamieson, C.; Palacios, P., comp. Proceedings of the 56th Annual Western International Forest Disease Work Conference; 27-31 October 2008; Missoula, MT, USA. Logan, UT: USU Department of Wildland Resources. p. 53-59.

Root disease pathogens, such as Armillaria solidipes Peck (recently recognized older name for A. ostoyae), will likely have increasing impacts to forest ecosystems as trees undergo stress due to climate change. Before we can predict future impacts of root disease pathogens, we must first develop an ability to predict current distributions of the pathogens (and their hosts). Reliable predictions depend on knowing precise locations of accurately identified pathogens and their host species. Thus, the goal of this study is to obtain baseline information on Armillaria spp. distributions in the East Cascades of Oregon. In 2007, a collaborative project was initiated to survey Armillaria spp. associated with diverse geographic areas and climate on the eastern slopes of the Oregon Cascades. Data from this project can be incorporated into models that predict current and future distributions of Armillaria spp. based on climatic factors.
