This is a press release from the Lost Coast Interpretive Association:

Sudden Oak Death is reshaping our local forests here in Southern Humboldt. Come learn more from Yana Valachovic,  Forest Advisor for University of California Cooperative Extension in Humboldt and Del Norte Counties, on Tuesday, January 21 at 7 pm at the Healy Senior Center. Since 2004 Yana has led a monitoring and management program for sudden oak death in the North Coast and for this program she will provide an opportunity for Southern Humboldt residents to hear how this disease is reshaping our forests, and to discuss the future of tanoak in our region. Yana is a registered professional forester and forest scientist whose skills and interests cover a wide set of natural resource fields including forest health, forest management, and fire ecology.

This presentation is part of an ongoing series from Lost Coast Interpretive Association, who brings environmental education to the Southern Humboldt community and is a member of the King Range Alliance, in partnership with the King Range National Conservation Area.

A sumptuous selection of desserts, as well as coffee and tea will be available for donation. Healy Senior Center is located at 456 Briceland Road in Redway.

  • I cannot attend but would love to hear more about this issue. Kym, do you think that a report can be published here after the meeting?

  • Thank you Kym I think everyone who lives hers but can’t make it to the lecture would vary interested in what is said It is our forest

    I learned a few facts about Phytopthera Ramorum (aka “Sudden Oak Death”)
    1. SOD is a variant descendent of the pathogen of the Irish Potato Famine fame
    2. SOD infects soft woods (pepperwood & Tan Oak,…) which may survive or die slowly, but
    3. SOD hits hardwoods (Oak, Madrone, etc…) most severely, hence the name “Sudden Oak Death”
    4. SOD can also infect poison oak
    5. SOD propagates multiple ways, and can travel great distances (especially in wet weather)
    6. Nurseries have also contributed to the spread of SOD

    • 2. SOD infects soft woods (pepperwood & Tan Oak,…) which may survive or die slowly, but

      Pepper wood and tanoak are not softwoods.
      Maybe you mean redwood? I’ve heard this disease can affect redwood.

      • The Hermit of Grizzly Mountain

        I mean that these two hardwoods-but-not-as-hard-as-oak-or-madrone get SOD but don’t die quickly or at all and continue to host the pathogen.

        IOW, The bigger (and harder) they are, the faster and more fatal is the onset of sudden oak death!

  • Thank you Mosby. Much appreciated

  • The pictures at the top of the article look exactly like hack and squirt herbicide application that is popular on forestry parcels. There is a big block up on Barnum ranch off 299 between chezem and titlow hill that looks like that. It is confirmed to be back and squirt. I wonder how to tell the difference

  • I’m really wondering if it’s the same fungus that kills port Orford cedars I think so ?
