Summary of the Day
Drier weather made access easier for our second day at the Yolo Bypass Wildlife Area, but it was still a bit difficult to find the site as the bypass was blanketed in a thick layer of fog all day! Students were troopers in the foggy, cold weather – it didn’t get above the mid 40s all day, and the sun never did come out.
We played “Where the Wind Blows” during our opening circle, an activity where students, mentors, and partners identify commonalities within the group. After this, we divided into mentor groups so each group could learn to identify mugwort, wild rose, California blackberry, coyotebrush, quailbush, and deergrass in preparation for the “Steal the Native Plant” game. Students raced to be the first to correctly identify each plant and earn points for their mentor group. This came in handy later – students were able to recall the names and ecological value of the plants as they planted them!
Alex Tremblay of Yolo County Resource Conservation District demonstrated proper planting technique before mentor groups headed out to tackle their trestles. You might recall that on this project we are helping to vegetate 4 former railway trestles, and each mentor group is adopting one! It requires a bit more flexibility than a typical SLEWS planting plan, as each trestle presents different challenges and obstacles. One group experienced extremely rocky soil, another had to avoid planting next to larger rocks. By the end of the morning, students had planted 350 container plants of native shrubs and forbs, and 80 deergrass plugs as “companion” plants!
After lunch, educator Sabreena Britt of the Yolo Basin Foundation led students in a water quality testing activity. After explaining the what’s and why’s of water quality testing, she had students rotate through 8 stations where they tested water turbidity, dissolved oxygen, salinity, conductivity, temperature, pH, total dissolved solids, and oxidation reduction potential. The data students collected was uploaded to Earth Echo International as citizen science data that can be used by real scientists! Check it out here: http://www.monitorwater.org/.
