Today I went out to assess the invasive Yellow starthistle infestation this year. I’m happy to say that it’s less than last year, but it’s still there. We may still be several years away from complete eradication.
But the really depressing thing to see is that Italian thistle is simply taking its place.
This has me thinking that my strategy needs to be this:
- Eradicate Yellow starthistle (essentially steady the course on what I’ve already been working on).
- Control Italian thistle in specific areas (trailside and on the Upper Meadow of the Sonoma Overlook Trail).
- Clone myself. I’ve already signed up Dan Noreen to join “Thistle Pirates” (see graphic) and I hope to sign up others as well. If you wish to join, let me know. You get a free t-shirt, but be careful, as it can come with an obsession.
If you wish to join us, let me know! People along the trail are very appreciative of this work.

I’ve been pulling Italian thistle (an invasive monster) since mid-November. It’s now mid-March and we still have very young plants coming in (see pic, gloved finger for scale). Today, I decided to call it the “third wave” but I have no idea if it comes in waves at all, or just constantly. Or if it comes in waves, how many can we expect? Five? Ten?
Recently I noticed that there was very little room to stand in front of our display at the top of the trail (see picture). Frankly, I couldn’t believe why that spot was chosen, when moving it several feet to the left would have been better by far. But whatever, it’s what we now need to deal with.
I finally gave up sooner than I would have otherwise, leaving a ridge of rock jutting up from the trail, since at the time I had no other choice. Perhaps later I can reduce it more, and create a smooth surface, but one battery’s worth of power is about all I can take on my wrist.
