Past information about spring 2019 Blitzes:
Test your trees for free!
Monitor disease spread in a rainy year, be on the lookout for new dangerous strains, and test oaks for SOD with OakSTeP
Things are not "as usual." Come learn to:
New this year:
- Leaves will be tested for the new and aggressive EU1 pathogen strain. Already in Oregon
forests, we need to look for it in California to have a chance of eliminating it if found.
- Introducing the OakSTeP program that will provide an easy and affordable way for licensed arborists, tree care specialists, preserve mangers and qualified government workers to test oaks for SOD. Join the OakSTep program for FREE if you register in person during a SOD blitz ($200 value), and get priority for sample processing.
- Thinking of doing something to control SOD, or have done so already? We'll have a questionnaire and important information and tips at the trainings.
- El Fairfield Osborn Preserve blitz es un evento bilingue (Inglés y Español)
