Title: Sudden Oak Death, Phytophthora ramorum: A Persistent Threat to Oaks and Other Tree Species

Author: Frankel, S.J.; Palmieri, K.M.;

Date: 2014

Source: International Oaks (Journal)

Publication Series: Scientific Journal (JRNL)

Description: This paper reviews the status and management of sudden oak death and “sudden larch death” in the urban and wildland forests of California, Oregon, and the UK. The causal pathogen, Phytophthora ramorum, was discovered in all three locations over a decade ago; however, efforts to contain and eliminate infestations have been unsuccessful. These less than satisfactory management intervention outcomes underscore the importance of prevention, for once forest pathogens become established, response is costly and difficult, and eradication is unlikely.

Keywords: Sudden Oak Death, Phytophthora ramorum, Notholithocarpus densiflorus, Quercus agrifolia, Larix kaempferi, invasive forest pathogens
