Planet Pala: Protecting Our Oak Trees
With the start of spring and warmer temperatures there will be a noticeable increase in insects and the diseases that they carry. One that is of serious concern is the Gold Spotted Oak Borer (GSOB), which is a flathead borer that causes mortality to oak trees. Experts believe it was introduced into the Descano area of San Diego County by the transport of infested firewood from Southwestern Arizona in 2004. The GSOB mortality of oak trees has since spread to other portions of San Diego County as close as Julian and isolated areas of Idyllwild in Riverside County.
