For the last five years we have been trying to eradicate the Yellow Star Thistle (YST) from the Sonoma Overlook Trail. For the the last three years we’ve also been trying to do the same for the Montini Preserve. Today I ranged all over the SOT upper meadows and emerged with about half a bag of YST. This is a great improvement, and demonstrates that our campaign is making a difference. There is now so little on the Overlook that searching for it may almost be a waste of time, so now I will switch to the Montini, which is likely to still have serious infestations of YST.
This year we also started tackling the purple thistle, which has overrun the Montini but hasn’t yet done so on the Overlook. We focused on getting it off the sides of the trail, as that is a primary way that it spreads. Next year we will begin earlier in the year fighting the purple (YST comes on later in Spring than the purple).
If you want to help out, let me know. I have contractor bags and the only other things you need are a glove and persistence.
Spring is definitely in full swing. Wildflowers such as lupine and California poppies are in profusion, as are the butterflies that frequent the also prevalent Blue dicks (like the Swallowtail pictured).
The trail is mostly no longer muddy (until the next rain, at least), so now is a great time to get out and enjoy the warmth and the wildlife. Just keep your eyes peeled for rattlesnakes, as they have already been sighted on the trail. Other wildlife to look for include squirrels, deer, lizards, and wide variety of birds, from Red-Tailed Hawks to Red-Shafted Flickers to Great Horned Owls (all of which have been sighted from the trails).
Another sign of spring is, well, a sign. We just replaced the sign at the top of the trail that describes a little of the history of the area and names some of the surrounding sights viewable from the upper meadow. On the Overlook Trail, costs such as these are borne by the volunteer Stewards of the Overlook Trail group, which
collaborates with the Sonoma Ecology Center that serves as our fiscal agent. But anything that costs money to maintain or upgrade the trail and property requires us to raise money through events, donations, etc. If you feel so moved, please click on our “Donate Now!” link in the righthand column. Or, come to our next event at the Sonoma Raceway.
In any case, enjoy all of the sights of spring and stay safe out there!
Faithful readers of this blog (all two of you, and one is my Mom) will know that we’ve been fighting the good fight against the invasive non-native Yellow Star Thistle on both the Overlook and Montini properties. The season for pulling it runs from mid-May to August. Now that we are in August, when the weed dries out and the seed heads drop off, we must quit.
But I’m here to tell you that we are winning the war. This is the second year that I can certify that all of the infestations on the main properties of both the Overlook and the Montini have been essentially cleared. Judging from the number and size of the plants we are pulling in most areas (see the small plants pictured), we are depleting the seed bank, which can be viable for up to five years.
We could not have reached this point without essential assistance from Rich Gibson, a biologist and a Sonoma Overlook Trail volunteer steward, and the Sonoma Ecology Center’s EnviroLeaders program. Twice, at least half-a-dozen teenagers from the EnviroLeaders Program came out and helped decimate the worst patches of Yellow Star Thistle on the Montini Preserve. Tony Passantino, the SEC’s EnviroLeader’s program manager, has been very willing to bring his team out to support our removal efforts whenever we called for help. And the teenagers who are a part of this program are willing hard workers and ready to learn about the environment and how to keep it great. We so appreciate their help.
Next season expect a call to go out for help in decimating this scourge. And if you see it, please consider helping. The situation gets better every year, but we are still years away from eradicating it completely. We can use your help to make YST only a memory on these properties.
Lately I’ve been too busy with a more important project to get my daily hike in on the Overlook and Montini trails. But yesterday I cleared some time and made my way there. I knew that we were well into the season of the invasive Yellow Star Thistle, so I took along a feed sack to pull what I could.
Those of you keeping score at home likely know that the Overlook Trail Stewards have been waging war against this pest, and that war has been stepped up in recent years. Last year we were successful in eradicating it from the main Overlook and Montini properties. We knew it would be back this year, but we also figured that given how we beat it back last year it likely wouldn’t be as bad.
Having inspected a couple locations where it was bad last year I’m happy to say that it isn’t nearly as bad this year. We are indeed making progress, but we also know that this is a multi-year war and that it will require us to be vigilant and relentless.
This war is led by volunteer Steward Rich Gibson, who has called work days for groups to get together and take out both Yellow Star Thistle and Scotch Broom – another non-native that has a tendency to take over the landscape. Without efforts such as these our landscape would look very different than what it should be, and has been for centuries.
To celebrate National Arbor Day, volunteer Steward Rich Gibson, a retired biologist, will lead a 3-mile hike of moderate difficulty on the Sonoma Overlook Trail while telling hikers about the trees and shrubs along the trail. This is not to be missed, as you will emerge from the experience with a much greater appreciation of the trees and shrubs you see not just beside the trail, but everywhere in Sonoma Valley.
There are two times to choose from:
- Friday, April 29th at 5:30 pm
- Saturday, April 30th at 9:00 am
For either day meet at the main Overlook Trail trailhead next to entrance of Mountain Cemetery. Be sure to bring water, sturdy shoes, and sun protection.
For more information leave a message for Rich at 707-939-0280.
If you like flowers, then now is the time to hike the Overlook and Montini trails, as they are going nuts. From California poppies, to Lupine, to you name it, they are out in great profusion. The picture to the right was taken just a few days ago on the Overlook Trail, where you can see both Lupine and Poppies hanging over the trail.
There are many other flower varieties out at this time, and others on their way. Spring is in full flower, and it is awesome.
However, keep in mind that other plants are going crazy right now, and among them is poison oak. Although we recently cut it back, it is still growing and we will likely need to cut it back again soon. Also, since the grass is growing like mad and often over-hanging the trail, keep an eye out for ticks. They like to climb up onto the tips of grasses where wildlife (and we count) are walking by so they can hitch a ride.
For tips on what to do if you are bitten, see this earlier post where I describe my own experience.
But by and large, it’s all good out there on the trail, and experiencing our wildflower bloom is well worth any slight risks.
