MARTINEZ — An expert on sudden oak death will discuss ways property owners can protect their trees against the disease in a free public talk at 6 p.m. Thursday at McMahon-Telfer hall, second floor, 604 Ferry St.

Matteo Garbelotto, head of UC Berkeley's forest pathology and mycology laboratory, will speak in a meeting sponsored by the Muir Heritage Land Trust, a conservation group.

Sudden oak death has killed thousands of California oak trees and infected some trees in open space areas that the land trust has acquired between Martinez and Hercules.

For detils, call the land trust at 925-228-5460.
