There’s Never Just One

Tripping down the trail today I thought to myself, “Oh, hey, there’s one!” I had spotted an invasive purple thistle plant at the trail’s edge (see pic). I stooped to pull it out.

As volunteer trail stewards, our remit includes not only maintaining the trails, but also helping the City of Sonoma to maintain their property that the trails traverse. This includes removing invasive species such as broom, purple thistle, and yellow  star thistle.

Purple thistle season begins in early Spring, which means we are already working to remove it. Later in the season the yellow star thistle will start to come in. Since we’ve been attacking the yellow star thistle for several years with vigor, we are seeing some real progress on eradicating it from the Overlook and Montini Preserve properties.

However, purple thistle is quite another story. Mostly due to years of cattle grazing, purple thistle has essentially already overrun the Montini Preserve. So at this point we only focus on yellow star thistle there. But on the Overlook, we think we have a chance to knock back the purple thistle so we are working on it as well. Since we only began our work on it last year, there is still quite a bit of it on the trail.

Today, as I stooped to pull the plant I had spotted I thought to myself, “Oh, wait, there’s five — no ten, crap, there’s a lot!”

I had momentarily forgotten that until the day when we reach the point of eradication — years, perhaps even decades from now (if ever), there’s never just one.

The Removal Season Has Begun

Each Spring we enter “removal season” on the Overlook and Montini properties. We begin with cutting back poison oak from the trail, as the runners begin encroaching as early as early February. So I was out today doing just that (see photo).

It was encouraging, though, as it seemed evident that previous years of cutting back the poison oak was reaping dividends. I was able to cover the bulk of the Overlook trail in one two-hour session.

After poison oak we will be on the lookout for Purple Thistle, as this non-native has been a scourge along the trail. We just started tackling this in earnest last year, so this year it will likely still be bad.

Following the Purple Thistle the Yellow Star Thistle will be coming in, by early March. That will likely keep us busy until early August. However, progress is being made on all these fronts and each year it becomes easier and easier, and some major patches are essentially already gone.

Once we get all these species under control, there are others we will need to tackle. Scotch Broom, for example, is one, although it isn’t as big a problem at the moment as the thistles.

If you want to help with this work, let me know! It basically takes a contractor bag (which I can supply you with) and gloves, although I frequently pull the Yellow Star Thistle gloveless.
