Sudden Oak Death Blitz 2017 results are in.

For the seventh year in a row, Napa “citizen scientists” participated with the UC Berkeley Forest Pathology and Mycology Lab in an ongoing effort to track Sudden Oak Death (SOD), the exotic disease that has killed hundreds of thousands of oaks and tanoaks in California.

The Napa SOD Blitz was held on May 6 and the results came out in October.

The disease is caused by Phytophthora ramorum, a microscopic organism that spreads during periods of relatively warm, rainy weather in late spring in northern California, according to the lab’s website.

Pen in Hand: Oak Woodlands — what the term means and why they are so important.

While the definition and criteria can vary from place to place, in general a "woodland" is an area with lots of trees, but they have what is called an "open canopy," meaning that the limbs and branches from one tree may sometimes touch the canopy of a neighboring tree, but they seldom overlap, and sunlight reaches the ground in most places.
