gary.maguireMonitoring for early detection of invasive Phytophthoras in WA State
Western Washington is a “high risk” area for diseases caused by P. ramorum and other Phytophthora species because of favorable environmental conditions and the abundance of susceptible host plants in wildland and urban areas. At present, P. ramorum has only been detected in or near nurseries in western Washington.
The spread of P. ramorum into the landscape will trigger a series of quarantines that will have a significant economic impact on the horticulture and forest products industry. Stream monitoring programs have been shown to be an effective approach to detect the spread of P. ramorum and focus eradication efforts to high risk areas, thus reducing the threat this pathogen poses to our landscape and forest ecosystems.
SOD monitoring in Washington:
- Volunteer Stream Monitoring for Invasive Phytophthoras
- Movement of invasive plant diseases between forests, nurseries, and restoration sites
- Population genetics of P. ramorum in WA state
- Phytophthora ramorum survey and monitoring locations 2003 – 2010, WA DNR
SOD monitoring elsewhere:
SOD National Detection Survey (US Forest Service)
SOD monitoring in California (COMTF site)
P. ramorum surveys in the UK (Forestry Commission)
