UC Berkeley Forest Pathology Lab is assessing the health of the famous oak near the cottage where Jack London lived and wrote. Dr. Doug Schmidt samples large branches to determine the extent and type of decay using the assay described at www.wooddecay.org. In the pictures see the majestic oak over 400 years old and the famous cottage.
When an outbreak of a disease has been identified, and due to extenuating factors it cannot be eradicated, it is important to implement strategies that minimize the effects related to the disease. This page is dedicated to mitigating strategies, called Best Management Practices (BMP’s), that may help minimize the abundance, spread, and negative impacts of the microbes responsible for plant diseases in large populations such nurseries or restoration efforts. BMP’s are based on scientific data, as well as on an intimate knowledge of the epidemiology of plant diseases. The purpose behind BMP’s is to minimize plant disease levels through a proportional and cost effective response for commercial and large scale projects that can scale effectively depending on the nature and scope of an outbreak.
The U.C. Berkeley Forest Pathology Lab has partnered with Calflora and Calfire to generate a guided tour of the Calfire Soquel Sate Demonstration Forest (Santa Cruz County) through the Nature Tour App. The App can be downloaded for free in its test version from Google Play wherever there is good cell reception. It then can be used in the forest to learn about its biodiversity, history, current management, and ongoing research activities through a self guided tour across 18 different stops. Signage with each stop number clearly visible is placed along an educational route through the forest. By tapping the number on the App that matches the number on the sign at each stop, the user will be able to play a pertinent audio description for that site. The audio can be easily interrupted, rewound, and restarted at any time. The language can be switched from English to Spanish, by changing the language in the general settings of your phone.

Emergent forest diseases threatening California Ecosystems
The course is organized in eight parts:
- Introduction to tree diseases and their causal agents
- Ecology of forest diseases, differences between native and non-native diseases
- Principles of Biological Invasions and diseases caused by off-site hosts or by forestry practices
- Emergent diseases in California caused by exotic fungi
- Emergent diseases in California caused by exotic oomycetes
- Newest threats
Readings and resources:
The following readings are general on the theory of emergent diseases:
The following readings are specific to the diseases covered in the workshop:
