Publication Series: Forest Insect and Disease Leaflet (FIDL)

Description: Annosus root disease is found on all western conifer species but is of most concern on true firs, hemlocks, and pines. Incense cedar, coast redwood and sequoia are sometimes infected in California. Western juniper is infected throughout its range. Annosus is common and causes extensive decay in old-growth western and mountain hemlock stands. Many mixed conifer stands throughout the inland west and California have high levels of infection, resulting in extensive mortality, especially of true firs.

Keywords: Disease, firs, conifer
