Summary of the Day
Of all the SLEWS projects so far this season, the two coldest days have BOTH been with Davis High School at the Yolo Bypass Wildlife Area! Our third and final field day was quite chilly and windy, but Davis students simply put on an extra layer and didn’t seem to mind. We attempted to warm up with a game of PVC golf (all four mentor groups were able to successfully transport the golf ball into the goal!) before heading out to finish our SLEWS project.

We had 106 container plants and 15 plugs to plant, and did quality control (securing tree tubes after some severe wind) on every plant on the four trestles. We thought we’d be lucky to finish all that before lunch. Imagine my surprise when the group finished…at 10:30am! Finishing early gave us time to to do some wildlife observation, and we were in luck because mentor Aaron Haiman is an excellent birder. He showed students how to use and focus their binoculars, and we set off on a birding adventure. Species we spotted included Horned Lark, Savannah Sparrow, Northern Harrier, Peregrine Falcon, Prairie Falcon, White-crowned Sparrow, Red Tailed Hawk, Western Meadowlark, blackbirds, and White-throated Swifts.

We also had time to do a reflection activity. Students found a spot to sit by themselves and had the opportunity to write a thank you card to someone who made their SLEWS experience possible. Students wrote note to mentors, restoration partners, their teacher, funders, guest speakers, and parent drivers – all people who were essential components of this project.

Since it was the last SLEWS Field Day, we had a mini celebration at lunch, complete with cupcakes decorated with trestle mounds and deer antlers! It was a throwback to photos students saw at the beginning of this project, an aerial view of deer trapped on a trestle mound taken when the bypass flooded last year. When the bypass floods next time, hopefully those stranded animals will find it to be much more suitable habitat, thanks in part to Davis students!

After lunch, students gathered to hear from Yolo Basin Foundation’s Corky Quirk, a bat expert. Corky even brought 3 live bats to show students (a pallid bat, a Mexican free-tailed bat, and a big brown bat). Students were absolutely enthralled by her presentation, and asked tons of excellent questions. Do all bats live in colonies? (No) How many babies do they have? (our native species tend to have just one per year) Does pregnancy affect their flight? (probably!) Are bats blind? (no) Do vampire bat bites hurt? (not really – their saliva contains an analgesic!) Corky discussed bats in the bypass and all around the world, and touched on topics like rabies, and white nose syndrome.

Like our first field day, during closing circle, we shared our favorite moment of SLEWS. On the first field day, however, many students answer was “the burritos!”. This time, only one student mentioned burritos – most students mentioned planting, birding, and bats as some of the highlights of their experience. What a great season with Davis High!

Summary of the Day
Our first morning in Capay Open Space Park was quick as we were trying to beat the heat – 700 beehives were near our planting area and we wanted to get as much done as we could while the bees were still relatively cold and inactive! After a game of Where the Wind Blows, we grabbed tools and headed down to Cache Creek.

To avoid walking by these 700 beehives, crossing the creek was our best option. Though the creek was shallow, it wasn’t shallow enough to make it across in our mudboots. Enter: the Argo. An amphibious ATV that works on land and water! Students donned PFDs and were ferried across in groups by Phil Zoucha of Cache Creek Conservancy.

Once everyone was across, we gathered for a quick refresher on plug planting. Students didn’t need much instruction as this was an activity we did on our first Field Day. Mentor groups each tackled a marked section and set to work plug planting – scraping away excess vegetation, “dibbling” a hole, inserting the native plant plug, and pinching the native soil over the top. Woodland High students really seem to take pride in being hard workers, and did a great job staying on task, checking the quality of their work, and helping their peers. As mentor groups finished sections, they moved to unplanted areas and even started makeshift “mulching” the plugs that were already done with the vegetation they scraped away. We planted all 1200 plugs in no time.

Before argo-ing back to the other side, we were able to spot some cool wildlife including a kingfisher, and the highlight of the day – a bird called a California Thrasher. While planting, students noticed many invertebrates including millipedes, worms, and a Jerusalem Cricket!

Our next task of the day was seeding. Depending on who you talk to in the RCD, you may hear this technique called “dinner plates” or “chia pets”. The basic technique is: clear a patch of soil (taking care to avoid native perennial grasses!), break up the soil, sprinkle seeds on top so they land about 1” apart, stir up the soil, and pack it back down. Mentor groups took on different areas of the park and planted seeds until lunchtime. Tanya Meyer of Yolo County RCD estimated we put about a pound of native seeds in the ground when all was said and done!

After lunch it was time for a SLEWS classic – mentor interviews. Sitting down and having a guided conversation with mentors about their education and career paths hopefully gets them thinking about what they may accomplish in their own lives. Students asked great questions including asking about mentor’s favorite plants, favorite college experiences, and what a “researcher” does exactly – and what they have figured out through science.

After this, students found space to sit by themselves and write and draw to reflect on the day. I saw some California Thrashers and well-planted plugs among the drawings!

With our “one word to describe the day” closing circle, popular words were “fun!” and “dibble!”. And I for one am very relieved to report we made it the whole day without a single bee sting!

Summary of the Day
Our second Field Day at River Garden Farms was warmer than anticipated, and thought it had rained the night before the dirt road was only damp, not muddy! After a breakfast of bagels and fruit, we got moving with a game of “Where the Wind Blows” before heading over for our planting demonstration.

Planting was tricky on this day – we were planting both tiny plugs and container plants, and putting protective tubes around each plant. Alex Tremblay of Yolo County Resource Conservation District gave a demonstration on all the necessary steps before we divided into mentor groups to play “Steal the Native Plant”, a variant of “Steal the Bacon”. Students learned how to identify sage, elderberry, coyotebrush, toyon, lupine, and wild rose before racing to be the first group to identify these native plants.

After gathering tools, mentor groups ventured out towards their assigned section. River Garden Farms had some tree tubes they wanted to reuse, but they were too small to fit around some of our larger shrubs. Students improvised to fit two tubes together to make one megatube that would fit around the plants! This was a slower process than usual, but students were meticulous in their work and did a great job planting. Some students began even naming plants as they went!

I have to hand it to Florin students for being so enthusiastic and dedicated to the project – this was the first time I’ve ever had to beg students to come back for lunch!

After some well-deserved burritos, students had the opportunity to interview all of the mentors about their differing education and career paths. I heard students asking mentors for advice and some great off-script questions, including “what’s your favorite superhero?”. One mentor, who’s in the restoration field, replied that he’d pick time travel so he could travel back in time to see what the area really was like so he’d be better at his job. Perhaps some of the same native plants that would have been around back then are once again back in the area thanks to Florin students!
