Sudden Oak Death

Oak trees are one of my favorite things. They offer habitat, shade and are crucial to soil development, watershed health, and recreation. Oak trees are hearty, surviving dry summers for hundreds of years. Their two main threats in California are poor regeneration and Sudden Oak Death.

Sudden Oak Death is a forest disease that was first noticed to infect trees in central California in the 1990’s.  Many trees, shrubs and plants are affected but the pathogen gets its name from the death is causes in tanoak, coast live oak, Shreve’s oak, California black oak, and canyon live oak. It also occurs in other parts of the world including Belgium, Netherlands, Germany, Spain, France, Poland, Sweden, Italy and the UK. The disease causes a variety of leaf and trunk problems, and often mortality.
