Sudden Oak Death Blitz

Thursday, April 25 – Petaluma

Saturday, April 27 – Santa Rosa, Sebastopol, Sonoma Valley, Yorkville

Sunday, April 28 – Penngrove

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.” At this one-hour meeting you will learn to:

  • Identify symptoms of SOD on bay laurel, oaks, and tanoak
  • Collect symptomatic leaves from bay laurel and tanoak to be analyzed at NO COST
  • Make important contributions to science

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)

Unless otherwise noted, you collect leaves at locations of your choice and drop them back at the meeting site that weekend. We drive leaves to UC Berkeley Lab for analysis on Monday. You get results in early fall.

Learn about what is happening with your trees and your forest. Find out if SOD is present. Contribute data on current disease distribution. Click here for more about the SOD Blitz

Bluebird Man

Bluebird Man is the story of 94-year-old Al Larson, a self-taught conservationist who has committed the last 35 years of his life to recovering North America’s bluebirds. Breathtaking scenery, intimate conversations and stunning footage of all three species of bluebird create a powerful film that reveals the secret behind Al’s longevity while providing inspiration for our next generation of citizen scientists.

Fencing Knot 1 – End or termination Knot

These instructional videos come to us from Tim Thompson, an Agriculture teacher from Australia who makes a new farm skill how-to video each week.

First of three videos showing how to tie up and strain a fence without needing expensive gimmicks. All you need are a good set of strainers and some pliers. The second Video can be found here;
