The Third Wave

Posted
Filed under Invasive Non-Natives, Invasive Species Removal, Italian Thistle, Winter

IMG-2727I’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?

All I know is that it will continue to come in for quite some time, and I need to keep an eye out for these little guys probably well into May. Part of the reason may be the very wet winter we are having, as none of the thistle is bolting yet but the plants, in some cases, are becoming very large. This presages a massive stalk, which will mean more bulk to deal with when we need to begin bagging the thistle and carrying it out.

Also, the rain is preventing me from using 30 percent vinegar to battle big patches, since I need sun to follow spraying, not rain that will wash it off. So far we haven’t many stretches of dry weather.

Sorry to be a Debby Downer, but these are just some of the challenges we face when attempting to control invasive thistle on these lands.

Making Room to Stand in Front of the Display at the Top of the Trail

IMG-2691Recently 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.

That’s when I decided that I needed to reduce the rock in front of it so people could comfortably stand in front of it and read the text as well as compare the picture to what they could view from that point. So I brought up our cordless rock chisel and got all medieval on the rocks in front of the display. The result is now what you see here (see picture). Although at first it was easy going, as the rock split along clear lines of weakness, it soon got harder, and I was literally chipping away at some very hard rock.

IMG-2693I 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.

Porter Abodeely and Sunrise Rotary Work Day Successful

Presentation School student Porter Abodeely, with the assistance of his father JJ, arranged and performed a trail workday with the help of Sunrise Rotary this past Saturday. Sonoma Overlook Trail steward Fred Allebach coordinated with Porter and JJ to guide the workers to the best jobs for the students and for the trail.

There were two crews, one focused on the kiosk area and the other on the upper trail. The kiosk crew performed these tasks: cleaned the trail entry, swept the kiosk area, moved rock thanking the Kiwanis Club for their trail donation back into place, removed trash, swept and weeded the entry staircase steps, cleaned the entry path drain, cleaned the drain above the staircase, swept the stone walls, lightly sanded picnic table top, and cleaned leaves out of table cracks.

The upper moved extra rocks from the new steps to a pile at the Toyon Trail junction, filled eroded areas in the new treads, raked gravel back out to the center of the trail and swept the steps.
The pictures are kindly provided by JJ and are published here with his permission. We extend our appreciation to Porter and JJ Abodeely, Sunrise Rotary, and Fred Allebach for making this happen!

Our Commemorative Book is Out!

us-letter-hard-cover smallAs part of our upcoming 20th Anniversary of the trail celebration, we decided to publish a book based on the entries that hikers have left in the notebooks that we have left on the bench at the top of the trail since the very beginning. That book is now out and available for purchase. The View from Above: Thoughts and Art by Sonoma Overlook Trail Hikers is a lovely 8 1/2″ x 11″ full-color coffee table book with photographs of both journal entries hikers have left and gorgeous trail photos.

Journal entries have been organized into chapters based on their essential message. Here are just some examples:

  • Appreciation
  • Gratitude
  • Love
  • Loss, Heartbreak, and Uncertainty
  • Philosophy
  • Advice
  • Determination
  • Encouragement
  • etc.

We also provide “interludes” of art, humor, poetry, and other entries that hikers have left in the notebooks.

At the beginning of the book we have written a short history of the trail property through the years and how the trail came to be (it was born in the midst of controversy). At the end we list all of the extant notebooks and all of the locations from around the world where our hikers call home (nearly all 50 states, several territories, and many countries).

We are selling it for $30, plus $2.70 sales tax, and for non-Sonoma Valley addresses, and additional $7.00 for shipping. You can make a check out to Roy Tennant and send it to 1212 Alberca Rd, Sonoma, CA 95476. We can also accept Venmo payments @Roy-Tennant.

Controlling Water on the Trails

Posted
Filed under Rain, Stewardship, Trail Maintenance, Weather, Winter

The Trail Maintenance Team for the Sonoma Overlook Trail does a variety of tasks, but one of the most important things we do is manage the flow of water across the trails. Essentially, what we try to do is to move the water off the trail as soon as it comes on. The best way that this happens is in sheet flow from the upper side of the trail to the lower side, but that is rarely the situation we can accomplish.

One challenge is that water often comes onto the trail not in a gentle sheeting flow, but in what is essentially a tiny creek. Another is that it isn’t always an option to have the water sheet off the downhill side. We often need to allow it to flow down part of the trail before directing it off in a waterbar (a channel we cut in the trail to force the water off the trail).

There are also other structures we build to manage water. Perhaps chief among them is the armored swale. An armored swale is essentially a deep channel you cut in the trail that you “armor” with rocks so it doesn’t erode as the water flows over it and off the trail. Another strategy we use to encourage sheet flow off the trail is cut the “berm” or the very edge of the trail that can build up in a way that keeps water on the trail instead of allowing it to sheet flow off of it.

All of these structures require ongoing maintenance, and the more subtle structures require more maintenance than the more dramatic ones.

Over the last few days (one of them during the recent rainstorm) I was out renewing the structures in place and cutting berm to better enable water flow off the trail. I also deepened a few waterbars and performed other tasks to better channel water from the trail.  I will again be out there tomorrow afternoon during the rainstorm with a shovel, to see what needs fixing. It’s part of what we stewards do.
