Interpretive Summary:

Technical Abstract: Phytophthora kernoviae, a recently described species of Phytophthora, is an invasive pathogen of forest trees and shrubs such as beech (Fagus sylvatica) and rhododendron (Rhododendron ponticum) that has become established in woodlands and public gardens in Cornwall, United Kingdom. Although the origin of P. kernoviae is unknown, the pathogen has been detected in New Zealand where only limited disease has been observed. In the United Kingdom, P. kernoviae occurs in some of the same woodlands as the sudden oak death pathogen, P. ramorum that has caused extensive losses to forests in California. Phytophthora ramorum quarantines have caused economic hardship to the nursery industry in the United States. Introduction of P. kernoviae to the United States could threaten both forests and nursery crops. This recovery plan is one of several disease-specific documents produced as part of the National Plant Disease Recovery System (NPDRS) called for in Homeland Security Presidential Directive Number 9 (HSPD-9). The purpose of the NPDRS is to ensure that the tools, infrastructure, communication networks, and capacity required to mitigate the impact of high consequence plant disease outbreaks are such that a reasonable level of crop production is maintained.
