Toward a west-wide model of Armillaria root disease: New surveys needed in western Oregon, western Washington, and Alaska

Abstract

Currently, Armillaria root disease causes large growth/volume losses (e.g., 16-55%) in areas of western North America (Filip and Goheen 1984; Cruickshank 2011; Lockman and Kearns 2016). Armillaria root disease is typically more severe in trees that are maladapted to climate-induced stress (Ayres and Lombardero 2000; Kliejunas et al. 2009; Sturrock 2011). Thus, it is likely that climate change will further exacerbate damage from Armillaria root disease, which can further predispose trees to beetle attack (e.g.,Hertert et al. 1975; Tkacz and Schmitz 1986; Goheen and Hansen 1993).
