Description: Phytophthora species are known as pathogens of agricultural crops or invasive pathogens destroying forests, and their prominent inclusion in various host-pathogen indices reflects this importance. It is increasingly evident, however, that Phytophthora species are abundant in streams in healthy forests and widespread in forest soils causing cryptic diseases, in addition to their more traditional roles as aggressive pathogens. While their ecology in non-agricultural ecosystems remains poorly understood, we now know that a numerous and diverse, nutritionally complex community of Phytophthora species is present in a variety of associations with forests and forest trees.

Keywords: Sudden oak death, Phytophthora ramorum, invasive species, tanoak, Notholithocarpus densiflorus, coast live oak, Quercus agrifolia, Japanese larch, Larix kaempferi
