Thank you Habitat Heroes!

A huge thank you to our incredible volunteers and board members who rolled up their sleeves and jumped into our first Habitat Heroes Workday on Saturday, January 11th, at Wavecrest Open Space! With tenacious volunteers, coupled with two dedicated CLT Board members, the group worked tirelessly to help restore vital habitat along this beautiful stretch of coastline.

The team tackled invasive ice plant that was creeping over native vegetation and threatening the area designated for the new Coastal Trail, which is set to be installed this summer. Despite drier ground conditions and strong winds, they made impressive strides—clearing much more than anticipated in a short amount of time.

Removing invasive plants is hard work, but our volunteers were up to the challenge! Their dedication ensures that native plants can thrive and that the future trail will offer visitors an uninterrupted view of the stunning coastal landscape. THANK YOU!!!

We’re excited to continue this important work and are deeply grateful to all of our Habitat Heroes for their time, energy, and commitment to protecting the coastside. If you’d like to join this amazing team, please reach out to info@coastsidelandtrust.org!

CLT Winter Art Show: "Subject, Activity, Place"- Presenting work by Half Moon Bay High School Art Students

CLT Winter Art Show: "Subject, Activity, Place"

Presenting work by Half Moon Bay High School Art Students

Please join us for the First Friday Show Opening and Artists' Reception on Friday, February 7th, 2025, from 4–6 PM at the Coastside Land Trust Gallery at 788 Main Street, Half Moon Bay.

We are excited to partner with Half Moon Bay High School art instructor Janelle Bracamonte to showcase pieces by her Art 3 class. She challenged her students to create truly original compositions, guided by three randomly picked components: a subject, an activity, and a place.

The students’ pieces are mixed media, using a combination of at least two of the following: watercolor, gouache, colored pencil, alcohol markers, and ink. The results are pure whimsy!

Finding an Old Growth Redwood Stand at Wavecrest

Photograph of Cleopatra Tuday- Biologist from SWCA Environmental Consultants

Bet we got your attention with that title! While CLT didn’t uncover actual old growth redwoods on the Wavecrest blufftops, we did discover a coastal prairie equivalent: a mature "stand" of Danthonia californica, or California oatgrass, a native bunchgrass.

In early January, biologist Cleopatra Tuday (from SWCA Environmental Consultants in Half Moon Bay) joined CLT’s Sara Polgar for a coastal trail project site project—and stumbled upon a 10’x10’ patch of this rare find. Cleo, a self-proclaimed botany nerd, was practically giddy about the discovery. As she put it, “Finding this on the coastal bluffs is like finding an old-growth redwood stand in the coastal mountains. Very old, very precious.”

She explained that you can spot Danthonia by the tripping hazard it presents—these bunch grasses create sharp, impenetrable clumps. Look for circular patches where the blades remain green even in the dry season, with grasses emerging from one central point.

Biologist Cleopatra Tuday (SWCA Environmental Consultants in Half Moon Bay) joined CLT’s Sara Polgar for a coastal trail project site visit in early January and found this 10’x10’ patch. Cleo is a botany nerd and she seemed a bit giddy about the find. As she described it, “finding this on the coastal bluffs here is like finding an old growth redwood stand in the coastal mountains. Very old, very precious.”

Also on the site visit, Sara and Cleo saw many chorus frogs (i.e. Sierran tree frogs) and even spotted their egg masses in a large puddle.

Junior Land Stewards- Word from the field

As we wrapped up the last few weeks of 2024 the Junior Land Stewards were busy in the field, as each school took its second field trip of the school year - combining ecosystem learning, journaling observation, and open space history.

Students from Hatch came to Wavecrest Open Space where they explored the 50 acres and participated in 4 journaling activities. These included: I notice, I wonder, It reminds of me; My Secret Plant; Ecosystem Inspection Circles; and Sound Mapping. Students explored life that is flourishing in the coastal prairie - from the indigenous plants to the pacific tree frogs.

El Granada students hiked up to the quarry floor at Quarry Park with a guided tour by Barbara Dye who taught them all about the history of their community, school, the Ocean Shore Railroad, as well as how Quarry Park became a protected open space. They then listened to the sounds around them and translated that into a sound map in their nature journals. Their final activity was My Secret Plant where they had to find an object in nature to draw in enough detail that their fellow classmates could find it by only looking at their drawing.

 At Farallone View, 4th graders had special guests Anthony and Jackson from the Golden Gate National Parks Conservancy lead them on a guided hike through the GGNRA. Along the way they examined the changing seasonal landscape, as everything is greening up again, and saw many raptors. The ground was wet but each student had their own special sit spot mat so they could get comfortable and focus on their journaling activities.

This program is supported by your generous support, as well as The California Coastal Commission's WHALE TAIL® Grant and the Maxwell/Hanrahan Foundation.

First Nature Journaling Workshop for Junior Land Stewards Teachers

Last week the Coastside Land Trust kicked off its first Nature Journaling Teacher Workshop of the year for the fourth grade teachers in the Junior Land Stewards Program (JLS). This workshop marks the first in a series of professional development sessions for these Cabrillo fourth grade teachers, aimed at enriching their teaching practices and deepening students' connection to nature.

Guided by veteran JLS educators, the teachers explored how to incorporate nature journaling into their classrooms, focusing on using numbers and data to enhance the upcoming JLS lessons. The workshop also highlighted how the JLS curriculum naturally aligns with English and Math standards, reinforcing skills already being taught.

Beyond the hands-on activities, teachers had the chance to reflect on the power of nature journaling to spark curiosity and scientific inquiry in their students. As the day ended, they were treated to a stunning sunset—a beautiful reminder of the wonders they’ll be sharing with their students this year.

From Seed to Science: Junior Land Stewards Dig In

The Junior Land Stewards have planted their seeds!! As they planted, the lesson focused on general planting strategies, as well as the beginning of a fertilizer experiment. Each student planted two seeds—one in a fertilized pot and the other in an untreated pot. This experiment will allow students to compare how fertilizer affects plant growth. Students will document their findings in their nature journals, noting differences between the two plants over time.

Throughout the project, students will ask important questions to guide their learning:

  • What do seeds need to germinate?
    What are the essential conditions for germination, including moisture, warmth, and air?

  • What do plants need to grow into healthy plants?
    Including sunlight, nutrients, and space for healthy growth.

  • How will we measure growth?
    Students will make plans for measuring their plants' height and tracking key growth indicators.

  • What will happen with the fertilized vs. unfertilized plants?

Over the next few months, students will carefully track the progress of their plants in nature journals, noting observations, sketching their plants, and recording data. This process will give them a deeper understanding of plant biology, the role of nutrients, and the scientific method.

Though they faced some inclement weather during planting, the JLS team was able to adapt by using the science rooms at Farralone View and El Granada Elementary. Thank you to these flexible teachers and administrators!!

Honing Nature Journaling Skills: HMB High School Field Guides

The Half Moon Bay High School Environmental Science and Marine Ecology students spent time last week developing their nature journaling skills. as part of their ongoing training for the important role of Junior Land Stewards field guides. Under the direction of Elexis Padron, this session guided students in the practice of nature journaling. Students learned to observe closely and reflect deeply through the simple yet powerful prompts: "I notice, I wonder, it reminds me of." These prompts encourage students to slow down, pay attention to the details, and cultivate curiosity about the natural world around them.

Each student selected a "nature treasure" — a plant, rock, insect, or any other fascinating object from the local environment — and began documenting their observations. Using various journaling techniques, they sketched, labeled, and wrote about their findings, all while learning to record the nuanced characteristics of their chosen specimens. Through this process of observation and reflection, the students honed valuable tools that will serve them well in the field.

We are grateful for Elexis and her powerful nature journaling lessons, as well as all of these students who continue to take on the important task of educating our local fourth graders about the environment. They are all contributing to the preservation, protection, and stewardship of the land we all love.

Exploring the Skies: A Recap of Yesterday's Raptor Walk at Wavecrest Open Space

Saturday's Raptor Walk at Wavecrest was a picture-perfect day on the San Mateo Coast. The weather couldn't have been more beautiful—a crisp, clear sky, with just the right amount of warmth to make the day absolutely ideal for bird watching. Over 80 participants gathered for the event, split into nine groups, each led by an expert guide from the San Mateo County Bird Alliance (formerly the Sequoia Audubon Society).

An Extraordinary Day for Raptors

As the groups set off across Wavecrest's expansive grasslands, the skies didn’t disappoint. Participants were treated to an impressive variety of raptors, including a special sighting of an osprey—a rare treat for those of us lucky enough to catch a glimpse. The highlight for many was watching the nesting pairs of White-tailed Kites and Red-tailed Hawks, two species that rely on the wide-open spaces of Wavecrest for both nesting and hunting.

Other notable sightings included Red-shouldered Hawks, Northern Harriers, and American Kestrels, all expertly pointed out by our knowledgeable guides. It was a raptor-lover's dream, with birds soaring above us, hunting in the fields, and taking advantage of the perfect conditions for a mid-winter meal.

Engaging Questions & Enthusiastic Participants

One of the best parts of the day was the lively, curious group of participants. People came from all over the Bay Area to take part in this special event, and the enthusiasm was contagious. Great questions were asked about everything from the hunting habits of Red-tailed Hawks to the migratory patterns of the Northern Harriers. Our guides did an excellent job of providing both expert insights and detailed explanations that kept everyone engaged and learning throughout the walk.

Wavecrest: A Critical Habitat for Raptors

The importance of Wavecrest as a raptor habitat can’t be overstated. This stunning open space preserve is the single most important site on the San Mateo Coast for wintering raptors. The vast fields, seasonal wetlands, and roosting sites provide the perfect environment for these birds of prey, which rely on the area for hunting and resting during the colder months.

Raptors such as the White-tailed Kite, Northern Harrier, and Red-tailed Hawk are regular visitors to Wavecrest, where they hunt small mammals and birds across the grasslands. The preserve is also home to a variety of other bird species, including Turkey Vultures, Sharp-shinned Hawks, Cooper’s Hawks, and even the occasional Rough-legged Hawk or Falcon.

By protecting these critical habitats, we ensure that these majestic birds will continue to return to Wavecrest season after season, and that future generations can experience the wonder of raptors in their natural habitat.

Thanks to Our Guides and Participants

A huge thank you to the San Mateo County Bird Alliance guides who led each group with expertise and enthusiasm, making this walk both educational and enjoyable. And of course, we want to thank all the participants who joined us yesterday. Whether this was your first raptor walk or you’re a seasoned bird watcher, your enthusiasm and engagement helped make this event a success.

Junior Land Stewards: A Fall Field Trip of Discovery and Action

Our Junior Land Stewards recently got out into the field - working hard to make a lasting impact on the land they’re helping to protect.

The students kicked off their trip by tackling one of the most important tasks in land management: invasive plant removal. Invasive species, such as non-native plants, can crowd out native vegetation, disrupting local ecosystems. By removing these plants, the students helped make room for native species that will better support local wildlife and foster healthier habitats.

Once the invasive plants were cleared, the students shifted to sheet mulching—a technique used to prepare garden plots for new plantings. The mulching process helps suppress weeds, enrich the soil, and retain moisture, all while preparing the ground for the native California plants the students will plant in February. Their efforts will pay off as they return to the site in the coming months to see the landscape transform with the planting of native species.

No JLS trip to the field would be complete without a little exploration, and the students took part in a naturalist scavenger hunt to document the wildlife and plant species around them. Armed with notebooks and keen observations, they recorded a variety of sightings, including:

  • Red-shouldered and Red-tailed Hawks

  • Harriers and American Kestrels in flight

  • Lizards basking in the sun

  • Bunnies hopping through the brush

  • Owl pellets left behind by nocturnal hunters

  • Invasive and native plant species

  • Signs of the changing fall season

By returning to the same site throughout the year, students will be able to see how the landscape changes with the seasons, observing how native plants grow, how wildlife behaves, and how restoration efforts make a tangible difference over time. The students’ hard work over the last two weeks is just the beginning of a long-term stewardship project. Their next visit will be in February, when they will return to plant the California native plants they’ve been preparing for. This will be a key moment in their journey as Junior Land Stewards—a chance to see how their efforts contribute to the restoration of vital ecosystems and to deepen their understanding of ecological sustainability.

These field trips wouldn't be possible without the The California Coastal Commission's WHALE TAIL® Grant.

We are also grateful for our many chaperones. Chaperones help keep students safe and engaged and make these trips happen. A big shout-out goes to all of you who have dedicated time and energy to supporting our program. Your presence makes a real difference, and we are deeply grateful for your commitment!

Stay tuned for more updates as our Junior Land Stewards continue their journey of discovery, action, and stewardship!
