Pine Pitch Canker
Pine pitch canker is a disease of pine trees that is caused by the fungus Fusarium circinatum. Pine pitch canker has killed so many Monterey pines that this ill-fated tree may disappear altogether. In inland areas such as Santa Rosa and San Rafael, Monterey pines are doubly cursed, afflicted with both pine pitch canker and deadly bark beetles.
