Green Hairstreak Corridor: Seed Collecting Workshop & Walk

***This is a special hands-on seed collecting workshop and walk where we'll collect seeds for next year's habitat restoration sites - great for beginners and pros alike! You’ll help us collect seeds to grow in our native plant nursery, or you can bring some home seeds to grow on your own!*** Help us collect native seeds to carry us through another season of habitat restoration in the Green Hairstreak Corridor. Folks who join these events help create and expand the ecosystem for this little green gem of a pollinator. We will be touring the Green Hairstreak Corridor, an urban wildlife corridor focused on protecting and building habitat for the Coastal Green Hairstreak Butterfly. We will stop at our various sites and learn about collecting seeds of various native plants. We emphasize biodiverse and ecologically relevant plants, and you will learn about many of our important native plant species. 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. Visit the Corridor on iNaturalist to see what's living there: [iNaturalist Monitoring Project](https://www.inaturalist.org/places/green-hairstreak-corridor) See our website to view a map of the sites: [https://natureinthecity.org/green-hairstreak](https://natureinthecity.org/green-hairstreak) We often work in light rain, but heavy rain cancels. **What to bring:** * long pants and layers (clothes that might get dirty!) * closed-toe shoes * water bottle * sun protection **Please sign our volunteer [waiver](https://forms.gle/szKbQEY3GXHegKJS9) before you arrive!** Click [here](https://www.google.com/maps/d/viewer?ll=37.75338433999246%2C-122.47148334999997&z=15&mid=1jyUAPD-wmfclOFwVvGiLU-byeWrlWXjM) to view a map of the Green Hairstreak Corridor sites. *There is no public restroom available in the corridor so please plan accordingly.*

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. August 13, 5:30am-7am Sonoma Coast, California All registrations must be completed on our website [here](https://www.forkinthepath.org/registration-urchin) #### What You Will 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. **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.

SAVE the TREES near a large Oakland air polluter

Nearly 90 new trees in the median need TLC. Park at 8000 Edgewater Drive median (off Hegenberger near Oakland Airport) parking lot. We have recently planted trees that need mulch, water and weed removal. These trees are currently alive, so now with this infusion of TLC, they will be safe until winter rains to resume growth. The temperature is likely cooler than most of Oakland as it is near the San Leandro Bay. You will need sun hat, water bottle and closed toe shoes. We will have gloves and water refill and a shade canopy.

Lake Merritt, oldest wildlife refuge

**What:** Let's gather and learn about the Oldest Wildlife Refuge in the United States. We'll learn about what lake Merritt was before it became a lake. And learn about some of the key players in that transformation. We'll also discover some of the botany and zoology in and around the lake. And finally, we'll discover some of the cool spots on the lake and some of the changes and challenges it's facing today. This will all take place in a casual and relaxed atmosphere. **What to bring:** We'll walk about 2 miles, easy walking with some easy inclines and stars, so a good pair of walking shoes, Binoculars if you have them, water and snacks. We can also do Zelle, Paypal, cash. **Where and When:** We'll meet and walk at two separate locations. One place at 9am-10am and the second place at 10:30am-11:30am.

Larkspur Library Habitat Gardenn

**Larkspur Library Habitat Garden** Monday, **August 24, 2026 10 – 11:30 am** Leader: **Dana Swisher, Helen Jenkins, and Catherine Wolfers,** [Refugia Marin](https://www.refugiamarin.org/) Come explore the native habitat garden at the new Larkspur Library. Stay for refreshments as well as a tour of the Refugia Marin gardens at Hall Middle School and Laura Lovett's Memorial Garden at the Central Marin Police Station, only steps away. [Refugia Marin](https://www.refugiamarin.org/) will lead an introduction, provide a plant list and garden layout map, and offer tours of the gardens. The newly-planted habitat garden at the Larkspur Library was designed to provide food and shelter for birds, bees, butterflies, and other wildlife as well as a welcoming public space for library visitors of all ages. It was designed in partnership with landscape architecture firm RHAA Landscape Architects and installed by [California Native Landscapes](https://cnlnatives.com/) (CNL). More than a decorative planting, the project reflects a growing movement to weave biodiversity into public spaces. The garden showcases earth-friendly gardening: sustainable landscaping that benefits the broader environment, while making things easier for the gardener. Earth-friendly gardening protects biodiversity by supporting pollinators and natural enemies, minimizes pollutants, saves water and energy, improves soil and recharges groundwater, and mitigates climate change. The [Marin Chapter of the California Native Plant Society](https://cnpsmarin.org/) provided meaningful support for the project, helping to make the garden a reality. The late [Laura Lovett](https://cnpsmarin.org/laura-lovett-tribute/), a Marin CNPS board member and passionate advocate for native plants, was deeply involved in shaping the habitat garden into the vibrant space it is today. The gardens (Library, Hall Middle School, and police station) showcase the larger [Larkspur Habitat Corridor](https://www.refugiamarin.org/larkspur-habitat-corridor), a series of nearby native plant gardens designed to help restore biodiversity by linking fragmented spaces into a thriving ecosystem. Future plans for the library garden include community habitat stewardship [work parties](https://www.refugiamarin.org/get-involved), the installation of interpretive educational signage about native plants and pollinators, as well as outdoor environmental learning opportunities through library programming. The new Larkspur Library is closed on Mondays, so we will share this special space with mostly the brave wildlife.
