Green Hairstreak Corridor

Help restore native plant habitat in the Inner Sunset district for the rare Coastal Green Hairstreak butterfly. Folks who join these workdays help create and expand the ecosystem for this little green gem of a pollinator. We emphasize biodiverse and ecologically relevant plants, and you will get to learn about many of our important native plant species. Be ready for activities like weeding, planting, seed collecting, pruning, and other land maintenance tasks. We often work in light rain, but heavy rain cancels. Please dress in long pants, closed-toe shoes, and layers - clothes that might get a little dirty! Bring your own water bottle and sun protection.

Buckeye Canyon BioBlitz

Buckeye Canyon offers a habitat quite different from most of San Bruno Mountain. Excessive rainfall in the November and December of 2022 set the stage for a tragedy. Then, on December 31, 2022 an atmospheric river dumped over six inches of rain in a continuous 12-hour period and caused a horrific landslide that changed the geology of the canyon from top to bottom. Now— 3 years later— the canyon is healing itself, and with some outstanding stewardship it is bending to mostly native species. We’ll conduct a bioblitz to assess the plants that have repopulated the erosion event. Along the way we will discuss the ecology of erosion events in a California Coastal climate and review of the science of erosion events as described by the USGS and other scientists. Bring your cellphone with the i-Nat application loaded, and a lunch or snacks and water and sunscreen. Contact David at [nelsondl@pacbell.net](mailto:nelsondl@pacbell.net) to register and get directions to the meeting place

New World Constellations (In-person, SF)

Hello, dear friends! Anita Pebbles and I are hosting our next New World Constellation gathering on Thursday, May 21st, in Golden Gate Park These constellations tend to answer questions we weren't completely aware were brewing, they bring us together around topics that allure and sometimes confuse us, and they are genuinely a good time! As we've shared before, these sessions aren't your usual constellations—they're more like experiments. Instead of focusing on personal pains or family systems, we're curious about what happens when we bring bigger ideas and shared cultural patterns into the circle and explore them together. We mean for this event to be a collective exploration and trust the group to guide us towards what wants to be revealed ​Let's use the magical modality of constellations to envision, gather information, and try on new realities. Together, we hope to increase ease, deepen connections, and grow more of what works for humanity and the Earth Think of this as stepping into a living experiment where we get to ask, "What else is possible?" and experience some of the answers now ​If this sparks something in you, or if you've been curious about exploring constellations in a new way, please join us! Logistics and planning: Time: We are planning to open at 6 p.m. with some discussion. Then hold a constellation with time for thoughts and sharing afterward. We'll close the space at 8:30 p.m. Location: This circle will be held outdoors in Golden Gate Park. We'll meet in the field behind The California Academy of Sciences on Nancy Pelosi Drive. [Use these coordinates in your map app to find us:] 37.770142, -122.463427 What to bring: Warm, comfy, layered clothes and blankets (can't emphasize this enough!!). Optionally, a folding chair, a pillow, a mat, water, a hot beverage, and, importantly, your thoughts and ideas around constellating for creating expansive futures for all Love, Caroline Find out more about me: carolineexner.com Send an email with any questions: hello@carolineexner.com

Foraging Wild Sea Urchin (Uni) to Restore Balance

**\*\*Register [here](https://forms.gle/khFPU5JZiwGxfKi5A), NOT on Meetup:** [https://www.forkinthepath.org/schedule](https://www.forkinthepath.org/schedule)[**](https://www.forkinthepath.org/schedule**) Save Kelp, Eat Urchin! Join us at sunrise for a sea urchin foraging class, where we will help remove some of the overgrown sea urchin population - so we can eat it! We will teach you how to open and enjoy this incredible delicacy. You may have heard it called “uni” in a sushi restaurant, but it’s SO much tastier when it’s fresh. Take home up to 35 urchin - if you can carry that much! Learn how humans can be a helping hand to restore balance to ecosystems impacted by climate change. Class Dates (not a series) * May 17 * May 31 * June 14 Sonoma Coast, California All registrations must be completed on our website [here](https://www.forkinthepath.org/registration-urchin) #### **What You'll Learn** We're thrilled to bring you to the ocean to forage for sea urchins on the gorgeous Sonoma Coast. This 3-hour class is all about sea urchins or uni, as you may have heard it called in a sushi restaurant. Learn where they live, what they eat, and who eats them...but more specifically, who hasn't been eating them and how that has impacted our kelp forests, and how humans eating them actually lends a helping hand to bringing our intertidal zone back into balance! Take home up to 35 urchins. You'll have a deeper understanding of how some of our ocean habitats are the first major biomes to experience sudden collapse due to a rapidly changing climate, and how we can mitigate the damage. #### **Where** A beach in Northern Sonoma, about 2.5 hours north of San Francisco. Exact location provided with registration. **Instructor** **Ricardo Romero Gianoli** has been living, foraging, and cooking in Northern California since 2008. One of his passions and career focuses is kelp forest restoration. Ricardo is a certified restoration scuba diver and kelp forest monitor who has surveyed sites from the Salish Sea to Orange County but he focuses his restoration efforts on the Sonoma and Mendocino coasts. It is his greatest joy to connect people with the ocean through adventure, food, and education in the intertidal zone. **Ryn Sullivan** brings over 10 years of experience in outdoor education and nature-inspired crafts to our team. As a backpacking guide, naturalist, and lifelong maker, they’re always finding new ways to work with what’s around us while caring for the ecosystem. They’ve been foraging since childhood and diving headfirst into their passion for the intertidal zone and all the creatures that call it home. They are involved in many sea urchin projects and are excited to teach Fork in the Path's students how to find and eat urchin as part of their holistic restoration efforts. When not foraging, you might find them teaching wilderness first aid classes, free diving for purple urchins, or crafting cordage from the irises in their backyard. Ryn is a certified Wilderness First Responder, yoga teacher, and California fishing guide. **Pricing** Our pricing is sliding scale $55-$125 with scholarships available. Kids are welcome too! **More Important Details** These programs are very popular and often fill up very quickly. We encourage you to register right away if you'd like to attend! If you are reading this, the class is not full. Space is updated daily. **About Fork In The Path** Fork In The Path offers transformational foraging experiences in California for the adventurous of all ages.

Ring Mountain Habitat Restoration Work Days

**Ring Mountain Habitat Restoration Work Days** Fridays, April 10 and May 8, 2026, 9:30am-12pm Leader: Amanda Magallanes, Ring Mountain Stewardship Coordinator Marin CNPS Coordinator: Caroline Christman Location: Ring Mountain Preserve, Tiburon Ring Mountain is well-known for beautiful views and stunning wildflower displays. Its serpentine grasslands are home to several rare plants including the Oakland star tulip ( Calochortus umbellatus ) and the Tiburon mariposa lily ( Calochortus tiburonensis ), which is found nowhere else. CNPS has a long history of supporting Ring Mountain and is continuing that work with a stewardship focus. Join us for 2nd Friday work days for a morning of hands-on work to protect native habitat. We will focus on removing non-native invasive plants, such as tocalote (Centaurea melitensis), false brome ( Brachypodium distachyon ), and Italian thistle (Carduus pycnocephalus). Removing invasive plants frees space and resources for native grasses and wildflowers to thrive. After a morning of rewarding work, Amanda will lead a short plant walk to enjoy the abundant wildflowers including tidy tips, goldfields, and owl’s clover, and to see if the Tiburon mariposa lily is blooming. During the work day we will be using hand tools to remove invasive plants and will be kneeling and working in tall grass. This location is exposed and can be windy. Marin County staff will provide tools and gloves. Bring a reusable water bottle and a snack, sun and wind protection, long pants, and sturdy close-toed shoes. Limit: 15 attendees Heavy rain cancels; cancellations will be posted on Meetup. Directions: Meet at the gate at the end of Taylor Rd. in Tiburon (dead-end street). From there we will walk together to our weeding site, which is approximately 0.3 miles with 100 ft of elevation gain (about a 10-minute walk).

4th Bay Delta Bioregional Unconference for Regeneration

Join us for the 4th Bay Delta Bioregional Regeneration Unconference on **May 9th, 2026**! Each unconference gathering has deepened our networks and sparked new collaborations across the region - and we keep coming back because something real happens in these rooms. At previous unconferences, participants have mapped 100-year visions for the [bioregion](https://baydelta.org/bioregionalism/), explored governance models from sociocracy to citizen assemblies, launched mutual aid networks, and sat with hard questions like "what do we tell our kids about collapse?" and "how do we bring more play into resilience work?" People have found unexpected collaborators, left with renewed energy, and built relationships that continue long after the day ends. Using **[Open Space Technology](https://en.wikipedia.org/wiki/Open_Space_Technology)**, there's no pre-set agenda. You bring the topics that matter to you - whether that's local food systems, land stewardship, Indigenous leadership, solidarity economy, bioregional tech, or something we haven't imagined yet. Our experienced facilitation team holds the structure so you can dive into the conversations that call to you. Whether you're running a community garden, organizing mutual aid, working on local policy, or just wondering how to plug in - you belong here. This is your invitation to join a growing network of people committed to a future that works for all life. **[Registration](https://events.humanitix.com/bay-delta-bioregional-unconference-for-regeneration):** Register online with sliding scale fees $50-1000, scholarships available: [https://events.humanitix.com/bay-delta-bioregional-unconference-for-regeneration](https://events.humanitix.com/bay-delta-bioregional-unconference-for-regeneration) **No One Turned Away for Lack of Funds (NOTAFLOF)** Scholarships and volunteer opportunities available!
