A note from UC Riverside Plant Pathologist, Akif Eskalen
We just confirmed that the riparian forest in the Tijuana river valley in San Diego is infested with Kuroshio Shot Hole Borer. Rod Dossey and his team from WRA, Environmental Consultants first noticed the sign and symptoms of the beetle on Sept 25th, and contacted us for the confirmation. I have visited the site last week and mortality is already occurring on many trees including Arroyo Willow, Black Willow and Castor Bean. Please let me know if you have any questions.
