News from Sedgwick Reserve
Hello from Sedgwick!

After a spectacular spring here at the Reserve, we are appreciating the last few late-comer spring blooms as the oak trees finish budding out and the grass gives way from green to brown. It's been a busy season at the Reserve; from UCSB field studies classes to botany workshops to biology researchers, the historic Sedgwick Ranch House and LEED-certified Tipton Meeting House have been abuzz with those passionate about studying our natural world. Read on for updates on our public lecture series, recent research at the Reserve, and more!

Happy trails,
The Sedgwick Team

Our next Walking Ecology lecture on
Sat. June 8th with Matthew Shapero

Join us on Saturday June 8th from 12:30-3pm for the next event in our popular Walking Ecology lecture series!

Walking Ecology brings together some of Sedgwick's most engaged and passionate scientists with our broader community. Walking Ecology events include an hour-long indoors lecture followed by an hour-long excursion with the presenter "into the field" to see science in action at the Reserve.

UC Agriculture and Natural Resource s County Livestock and Range Advisor Matthew Shapero brings his background in farming, ranching, and rangeland sciences to bear in his current work advising ranchers and landowners in Santa Barbara County on the latest in range management, climate change resiliency, and sustainable practices.

Curious about how our changing climate conditions are going to impact the status and composition of our local grasslands? Join Matthew for an informative, accessible journey into the impacts of climate change on our local rangelands.

Registration is required for the field component only of this event, and will open on Friday May 24th via our website and email list.

Sedgwick's La Kretz Research Center Blooms
When long-time Sedgwick donors Linda La Kretz Duttenhaver and Morton La Kretz dreamed up a groundbreaking vision for the La Kretz Research Center at Sedgwick Reserve , they brought to the table an image of a one-of-a-kind research program that would allow Sedgwick to proactively craft and execute a cutting-edge research agenda that would benefit our region, California, and beyond. Nearly two years down the road from its inauguration, the LKC is already making waves in the UC and Natural Reserve System communities. Director Frank Davis , a long-time Sedgwick oak researcher and professor at UCSB's Bren School, has brought on board three talented graduate student fellows, kicked off plans for an autumn research symposium, solicited a Sedgwick-focused postdoctoral researcher, and more. We're thrilled to be watching dreams become reality through this new Sedgwick-based program, which is truly one-of-a-kind within the UC and the NRS.

Restoration Landscaping at the Sedgwick Ranch House
Did you know? Recent estimates suggest more than 98% of California's native bunchgrass stands have been eliminated. These beautiful, stately grasses lend more than just aesthetics to our regional grasslands--they also have Sedgwick staff, docents, and more than a few visiting undergraduate and graduate students from across the University of California lend their hands this winter and spring to plant more than a thousand native bunch grasses at the historic Sedgwick Ranch House as part of a restoration landscaping project, thanks to the generous support of donor Linda La Kretz Duttenhaver.

Over the course of a year, native plant restoration expert Ayumi Nakamura has been busily collecting seed and cuttings from around the Reserve, propagating bunch grasses by the thousand, and overseeing efforts to plant these ecologically significant grasses around the perimeter of the historic Sedgwick Ranch House, built by the Sedgwick family during their tenure on the ranch in the 20th century.

Staff Profile: Resident Steward Lyza Johnsen
Anyone who's visited Sedgwick knows our Resident Land Steward Lyza Johnsen keeps the place working like a well-oiled machine. From overseeing trail work on our nine square miles of protected acreage to fixing broken powertools, Lyza handles both the micro and the macro around Sedgwick.

How long have you worked at Sedgwick? I worked here part time for almost two years and started as the full-time steward in June 2018.

What's your favorite aspect of your job?
The part of my job that I like the most is just being on the property and enjoying the flowers and the nature. I love to see the docents and all the people that come out—the kids programs especially, getting to see the joy they have in nature, getting to see their experience of this place. That’s really the thing that I like best. 

What's your favorite place at Sedgwick?
I love Pine Needle Valley and I also love a spot up Windmill Canyon atop a peak—you can see a great view of the Reserve and the other mountains from there. But I also love a spot at the tip-top of the Reserve where all the pines are too! There are so many beautiful places but those are my top three. 

What are your other hobbies? Paddleboarding, hiking, just basic adventuring! And backpacking. I’m also a docent at the Pismo Preserve. 
In Memoriam: Jean Schuyler
This month, we're remembering and celebrating the life of extraordinary local environmental advocate and activist Jean Schuyler , a long-time friend of Sedgwick Reserve and Santa Barbara County's natural environment.

Jean passed on April 17th, after more than 40 years of staunch speaking-out for protected lands in our bioregion. We honor her once-in-a-generation commitment to our natural environment and our local community.
Sedgwick's Rare Vernal Swales Fill and Flourish
After a much-needed wet winter around here, Sedgwick staff and docents alike were delighted to discover our rare vernal swales had filled with water. Vernal swales are a type of ephemeral wetland ; they are depressions in the landscape that fill with water only during certain years, and only for a short period of time--often just a couple of months. Because they do not fill with water every year, they are often thoughtlessly lost to development and urbanization; it's hard to protect a wetland that's only obvious some of the time. Sedgwick's vernal swales had not filled with water since 2011. These unusual wetlands support a diversity of unique species. From December to April, we enjoyed the slow emergence of vernal swale-associated flora, from Eleocharys macrostachya (a spike rush) to the golden groundcover of species of Lasthenia spp. (goldfields). While we're sad to see the water dry up, this is a natural part of the vernal swale cycle--seeds of these plants can persist for years in dry ground, awaiting another wet winter and another chance to bloom.

Game Cameras Reveal Reserve Wildlife Up-Close
Thanks to the partnership and support of UCSB's Chandra Krintz and Rich Wolski and the devoted boots-on-the-ground volunteer support of local student Grant Canova-Parker, Sedgwick's vibrant camera trapping program has continued to provide incredible footage of the many animals which call this 9-square-mile Reserve home. Why record wildlife with motion-sensitive cameras? For researchers and land managers, it provides valuable information on what animals are--or aren't--present in a particular area and during a particular time of year. Most importantly, it gives humans like us the chance to see amazing shots of wildlife we'd never otherwise be able to witness.

Through the Sedgwick-based "Where's the Bear?"research initiative, Drs. Krintz and Wolski have been working with Sedgwick to investigate and automate the image processing process, saving hours of time along the way and generating important findings regarding the ability to automate these processes across the biological research world. Read more about Where's the Bear in this 2018 news piece .

Wildflowers of Sedgwick: A Photo Diary of Staff Favorites
It's been an amazing spring for wildflowers at Sedgwick. After years of drought, the Reserve was blanketed with a diverse array of annual forbs, perennial bunchgrass blooms, lushly budding oak trees, and more.
Clarkia purpurea ssp. quadrivulnera . Clarkias are often known as Farewell-to-spring because they are one of the last wildflowers of springtime to come into bloom.
Ribes malvaceum , known as chaparral currant, lives up to its name by producing prolific quantities of tart red fruits that support a plethora of wildlife.
This rare plant, Calochortus catalinae (the Catalina mariposa lily), was recently identified and logged through a California Native Plant Society "Rare Plant Treasure Hunt" with visitors participating in a botany workshop held at Sedgwick and hosted by The Wildlife Society.
Another eye-catching flower in the genus Calochortus, these delicate "fairy lanterns" ( Calochortus albus ) grow in cool riparian corridors at Sedgwick.
The subtly electric-blue flowers of Sisyrinchium bellum , blue-eyed grass, hints at its membership in the iris family.
