Summary of the Day
Our second Sac Valley SLEWS day of the year brought us to the confluence of Putah Creek and Dry Creek in Winters, CA. Landowners Michael Barbour and Valerie Whitworth have been working with Yolo County Resource Conservation District to plan a habitat restoration project in an area that was damaged by fire in October 2018. This will increase biodiversity in the area as well as provide habitat for pollinators and the wildlife of the creek. We were happy to involve Winters High School students with this project, walking distance from their school!
After students arrived on foot and enjoyed breakfast, we gathered in our opening circle to introduce ourselves and the project goals, and learn names with a round of group juggle. From there Amy Williams of Yolo County Resource Conservation District led us towards the creek to teach us about a very important plant – blue elderberry. There are special rules and protective measures surrounding this plant. Why? It is the only host plant for the Valley Elderberry Longhorn Beetle, a federally protected species of insect. Its habitat has been greatly reduced due to agriculture and urban development. To protect the beetle, the blue elderberry plant is protected from disturbance, trimming, and removal. Our project site has a sizeable elderberry shrub in the middle of it, so we took extra precautions to make sure it was not damaged during our work.
To start our project, we had to move a bunch of brush that was in the way of our project site. Though there was a sizeable amount of cut branches, students and mentors made extremely short work of it. Next the entire class gathered together to lay out the longest irrigation line. This is a group effort – students space themselves about 20 feet apart and carry the line all the way to the end as the spool of irrigation tubing unspools. One this line was “stapled” down, students got in their mentor groups to divide and conquer.
One group worked on installing emitters on existing oak trees, another created a “grid” of irrigation for the pollinator meadow, and the other two groups laid out 3 more lines of irrigation in the main planting area, taking care around the elderberry of course. By lunch time, students had installed 2500 feet total of irrigation and installed 280 emitters!
Once we were done eating, we ventured down to Putah Creek where Amy and mentor (and biologist!) Corey Shake talked about the significance of the creek and the wildlife that calls it home – especially spawning salmon! We even saw some wildlife of our own on the field day including western fence lizards, a fuzzy caterpillar, beetles, and birds. After exploring the creek, students found a quiet spot to sit and reflect on their first field day in a field journal. This low energy activity was probably a welcome end to the day – a mentor’s fitbit tracked that we walked 4 miles while working throughout the field day, not even counting the students’ walk to and from school!
