Armillaria altimontana is not associated with reduced growth or survival of western white pine (Pinus monticola) planted in northern Idaho

Abstract

Armillaria altimontana and A. solidipes frequently co-occur (McDonald et al. 2000) and are commonly found in association with western white pine (Pinus monticola). Armillaria solidipes (as A. ostoyae) is well-known as a virulent primary pathogen on diverse conifers within inland western regions of the contiguous USA (Lockman and Kearns 2016), whereas A. altimontana is considered to be a weak or secondary pathogen (Brazee et al. 2012). However, little has been documented about the impact of A. altimontana on tree health and growth.
