Announcements 2010


Announcements

The baiting for the 2010 pilot study is now complete. We are in the process of isolating and identifying all the Phytophthora species. Check out the results pages for the latest information.

Thanks to everyone for helping out with this project. We will be having a meeting/lunch event to look at our results and talk about next years monitoring towards the end of July. If you have ideas for other locations to monitor in 2011, let us know.


After two baiting intervals, we are happy to report that there has been no P. ramorum detected at any of the sites. Several different Phytophthora species have been isolated but not identified.


Thanks to the US Forest Service for providing two years worth of funding for this project!

Initial bait deployment and volunteer training is scheduled for four sites during the first week of March.

We will be holding a training session for people who wish to volunteer in the lab doing sample processing and Phytophthora identification sometime in mid-march. If you are interested in lab work, let Marianne know.

Announcements

The 2011 monitoring is completed. Check out the results pages for the latest information. Thanks to all the students and volunteers who helped out. A number of interesting projects have been done by students in 2012 using isolates collected in the 2011 stream survey. We have also found some possible new species of Phytophthora, Pythium, and Halophytophthora. The 2011 survey provided some baseline information about the oomycete (aka ‘water molds’) flora of western Washington streams with a variety of land uses.


We’re gearing up to start the 2011 monitoring study. Check out the sites page to see where baiting is being planned. These are subject to change until the weeks of Feb 21-25 and Feb 28-Mar 4, when we set up the sites and deploy the first bait leaves. This year we will have some salt water sites in addition to freshwater streams, so we will learn more about Phytophthora and Pythium species found in those environments. Check this page to see dates and times for setting up your monitoring site.


Save the date – Thursday July 29 from 10 – 2 pm at WSU Puyallup. We will look at our results from this years monitoring and start planning next years. Lunch will be provided. RSVP Marianne Elliott (melliott2@wsu.edu)

Volunteer Stream Monitoring for Invasive Phytophthoras


Stream monitoring for early detection of invasive Phytophthora species in Western Washington

The Phytophthora stream monitoring program at WSU Puyallup

In this project, we are involved with

  • Gathering baseline data on Phytophthora species present in western WA urban and wildland areas
  • Early detection of invasive Phytophthora species
  • Track the movement of P. ramorum from infested areas
  • Expand on the streams currently being sampled by the WA Dept. of Natural Resources as part of national P. ramorum survey and on nursery surveys by WSDA
  • Continue molecular identification of Phytophthora species and their genetic lineages

Student Projects

What is Phytophthora?

  • A “water mold” closely related to brown algae and diatoms
  • Pathogen spreads via the movement of infected plants, contaminated soil, aerial and water-borne spores
  • Causes economically important plant diseases such as potato blight and sudden oak death
  • Phytophthora diseases on plants are identified by symptoms, microscopic examination and molecular testing
  • Read more about Phytophthora and other Oomycetes here.
Invasive Phytophthora species
One way to stop the damage an invasive species such as Phytophthora may inflict on an ecosystem is to control or eliminate the species when its populations are still small. Students and other volunteers can help scientists by conducting early detection surveys. Unlike many well-known invasive species, Phytophthoras are microscopic and must be detected by indirect methods, such as baiting with leaves of susceptible plant hosts. 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.

How to get involved

We are looking for volunteer groups, students, or other people who are interested in helping monitor streams in Western Washington for P. ramorum and other Phytophthora species. We need people who can access selected streams and place bait bags or collect water samples at regular intervals and can return these samples to the lab. If you are interested in participating, let us know.
