Goldspotted oak borer continues to spread
The invasive beetle, goldspotted oak borer (GSOB), has been found in the mountain community of Sugarloaf near Big Bear in San Bernardino County, reported the Chino Champion. The detection causes concern for other nearby communities where oak trees are prized.
"It realistically should be treated like a quarantine situation," said Doug Yanega of the UC Riverside Department of Entomology. "All it takes is a few people who don't know any better or think the rules don't apply to them to infest new areas."
The Chino Hills area has nearly 4,000 oak trees in parks, landscaping and parkways, not including trees on private property and city open space.
"The goldspotted oak borer posts an unprecedented threat to native oaks in Southern California," said UC Cooperative Extension specialist Mark Hoddle, director of the the Center for Invasive Species Research at UC Riverside. "Hiking trails and campsites have been closed because of the risk of branches dropping from dead trees."

Avocado growers: Your Participation is Needed Please
The California Avocado Commission is joining forces with Kevin Turner, UC Cooperative Extension goldspotted oak borer (GSOB) program coordinator (http://ucanr.edu/sites/gsobinfo/) in producing and distributing a number of roadside signs to help control the movement of pest infested firewood.
They are asking for avocado grower's participation in areas that are susceptible to the GSOB and/or the Polyphagous Shot Hole Borer (PSHB). GSOB susceptible areas include oak woodlands and forests while PSHB environments include avocado groves. Some of these susceptible locations are primarily focused in the Fallbrook, Escondido, Valley Center, and Alpine areas. Eventually signs will be developed that will feature both the GSOB and the PSHB and discourage movement of oak and avocado wood.
The signs can go in a variety of frame designs. Most signs are 4' x 8'and are normally inserted into a redwood frame, but can be as simple as posts and a piece of exterior plywood onto which the thin aluminum sheet sign can be attached. The signs should be placed visibly along major roadways or busy streets.
If you would like to participate by permitting signs to be placed on your property along major streets, please contact:
