Summary of the Day
As you may recall, our SLEWS project with Woodland High School is actually two projects – two days at the Maples in Woodland, and two days at Capay Open Space Park. This was our third field day after one at the Maples and one at COSP, making it our final day at the Maples.

We had a small crew on this day which made PVC golf trickier than usual (you have to run FAST to get to the front of the group before the golf ball does!) but two groups won the game incredibly quickly. After that, it was time to group up to learn about the restoration work for the day.

Since we planted all the plants on our first field day here, our next task was to make sure these plants are given the best chance at survival. Installing “tubex” tubes around each plant will help protect them from pests, herbicides, and wind and will create a mini greenhouse for the young plants. Before installing the tubes, students checked to make sure the emitter was working properly, and created a soil “berm” on the low side of the plant to prevent all the water from flowing into the basin. But one of the biggest problems for these plants will be competition from weeds! To combat this, we mulched around each plant with a THICK (two “leaves” or “flakes” worth) of straw. This will prevent weeds from growing up around the plant, so they’ll have better access to resources like water and sunlight.

Speaking of weeds – there was already tons of cheeseweed and milkthistle sprouting up in our planting area. After a quick lesson on how to identify these pesky weeds, students set to work attacking each and every one! Students were very inquisitive as they worked – asking what benefit weeding would have for the plants, and asking to be reminded of the species we planted last time and their role in the ecosystem.

After lunch, we donned binoculars and set off to explore nearby Cache Creek. We spotted many different species of birds and took some time to relax and enjoy the view from the levee.

At closing circle, students were asked what they had learned that day. Popular mentions were how to identify milkweed and cheeseweed, how to use binoculars, and the benefits of mulching. As for favorite moments of the day, the clear winner was a surprise – weeding!

Summary of the Day
“How did today go?”
“FIVE STARS!”
After each Field Day, I ask this question of our mentors and project partners in order to get feedback and look for ways to improve the SLEWS Program. Never have I been met with such an enthusiastic response! Read on to see what happened on this beautiful, five star day.

We started with a game of PVC golf before heading down to the restoration site to finish our part of the project. On their Field Day two weeks prior, Pioneer High did not have time to finish planting all of the native plants on their irrigation line. Our priority was getting these plants in the ground, so Grant Union students took this on, planting 65 native plants. Another priority was installing emitters along the line so that each plant would receive a consistent water source (especially as it’s been a very dry month!). Once emitters were in, we turned the irrigation system on to make sure it was working properly. Usually when we do this check, we find multiple “geysers” along the line – spots were emitters were not installed properly and pop off due to the water pressure, spraying water everywhere. Shockingly, we found no geysers! Grant Union did a perfect job! We also were able to plant 24 plug plants, but since the ground was too hard to use a dibble, this was done with trowels.

On our very first field day, we noticed a tall hill that looked accessible, so after lunch and a last-field-day celebration of SLEWS-themed cupcakes, we began the trek. The walk was not far but it was steep, and we all had to catch our breath at the top – especially those that chose to literally run and race up the hill!

I figured there would be a decent view from the top, but was absolutely blown away by the stunning panorama that awaited us. The excitement atop the hill was palpable – after taking some time to soak in the view, we passed out supplies for students to design and write a thank you card to someone who made their SLEWS experience possible. Many students wrote to their mentors, and others wrote a general thank you to all who helped plan their field trip.

We had our closing circle at the top of the hill where we shared our favorite memories from all three field days we had shared. Popular answers included hiking to the top of the hill, being out in nature, installing emitters, planting trees, seeing wildlife, teambuilding games, and enjoying the beautiful weather. Michael Felipe of Yolo County Resource Conservation District had come upon many tiny bones at the top of the hill, which we realized came from raptor casts or owl pellets – he shared his finds at closing circle.

It was amazing to close out the day with a view of not only our project, but also earlier phases of the restoration efforts at the site – we could clearly see how our piece connected to the rest of the wildlife corridor.

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!
