Summary of the Day
The morning of this Field Day was the coldest so far – it was 28 degrees when I arrived to load up the truck with gear in the morning! After finding another water source (the faucets were frozen shut!) we loaded up the truck with hot water for cocoa and were on our way, passing frost-covered cows on the drive.

The restoration site was at the end of a dirt road that had become quite muddy in recent rains – just getting there was a 4wd adventure! Rio Vista High soon arrived with a small but mighty crew of students. After changing into rain boots, we were at our field site in no time.

We started our first Field Day with opening circle, where Chris Carlson of Solano RCD introduced the multi-year project at Petersen Ranch. Just last year, students from Rio Vista High installed irrigation, planted grasses, trees, and shrubs and installed bird boxes. This year’s students will help put the finishing touches on this restoration project. After a game of “Where the Wind Blows” where we learned Rio Vista students enjoy fishing, welding, and spending time outdoors we divided into mentor groups and gathered supplies for the day.

Chris led an informative and entertaining demonstration of our activity for the day – planting “plugs” of native grasses, forbs, and sedges. Mentor groups tackled different areas near the irrigation ditch, planting plugs of mugwort, purple aster, western goldentop, creeping wildrye, and saltgrass. Groups working further from the water source also installed drip emitters on the irrigation line and placed a protective covering around the plug. Rio Vista students worked incredibly fast – 800 plugs were in the ground in under an hour! Luckily Chris had some acorns ready for planting, and explained how oaks planted from acorns tend to live longer than those planted from saplings, as the tap root is undamaged. Students made short work of these acorns as well, planting 15 acorns in the riparian area. It’s amazing to imagine how different the area will be when those trees start to mature!

We still had some time before lunch, so mentor groups grabbed binoculars and bird ID cards and ventured up onto the levee. Some of the bird species we spotted included white-tailed kite, marsh wren, turkey vulture, red tailed hawk, white crowned sparrow, caspian tern, and lots of raptors. After lunch, we returned onto the levee to spend some time reflecting on the day in field journals. Students were great about spreading out to experience the site solo – some students were perched on the levee, while others found quiet spaces near the water.

At closing circle, many students remarked that they most enjoyed learning how to plant and spending time outdoors. Mentors and partners enjoyed this as well, but the adults in our group were most pleasantly surprised by this awesome group of respectful, hardworking, and fun-to-be-around students. Can’t wait for our next day in the field!
