Summary of the Day
Our second Field Day with Davis High School brought us to a new location – Dry Arroyo Creek between Dixon and Winters. There have been several SLEWS projects in this area over the years, and Solano Resource Conservation District invited Davis High students to put some of the final touches on a restoration project many years in the making.
After breakfast, we learned more about one another through a game called “Wind in the Willows”. This game allows us to identify commonalities within the group, and strengthen our bond as a SLEWS team. Then, Solano Resource Conservation District staff led us in a demonstration of our restoration task for the day – plug planting native grasses! Students learned to use a “dibble” to poke holes in the ground, insert a grass “plug” (a small clump of native grasses) and pinch the soil over the top to prevent moisture loss. The hope is that these native grasses will outcompete invasive grass species, to improve soil stability and water retention and increase biodiversity.
Once students got a hang of the process, mentor groups spread out along the bank of dry arroyo creek and began planting grass plugs every 2 feet in a grid-like pattern. These grasses will eventually grow to fill in the entire area. I had one student ask me to further explain the impact these grasses will have in the area, and I appreciated her wanting to put the project into context! There were some very impressive feats of teamwork with some students measuring, some students “dibbling”, and students following to plant the grass plugs. By lunchtime, students had planted around 2000 native grass plugs!
Students had been eager to explore Dry Arroyo Creek all morning. Lucky for them, after lunch, Sarah McKibbin of Solano Resource Conservation District led the students across the creek on a native plant walk to see some of the plants that have become established through the restoration effort. Then students were given time to explore the creek and adjacent areas in mentor groups, identifying native plants and birds. One group even found a frog in the creek! As groups were exploring, Davis High teacher Sherri Sandberg rotated mentor groups through a water monitoring activity to assess the water quality of Dry Arroyo Creek.
