Earth Day 2025: Be Part of a Statewide Movement to Restore Our Parks | Cal Parks
Published: March 11, 2025

As Earth Day approaches, California State Parks Foundation is gearing up for a month-long celebration of climate action and stewardship in state parks. We are proud to continue our 25+year tradition by providing grants to parks and hosting volunteer workdays throughout the state. Our events invite the community to come together to build climate-resilient parks for future generations. As we reflect on the incredible impact we’ve made through past Earth Day projects, we invite you to revisit the parks you’ve helped improve and see the lasting changes your efforts have brought to life.  

This year, 10 of the 12 events will be held at parks that we worked at last year, and we host monthly volunteer workdays at many of these locations, too. Consistent stewardship creates a lasting impact, and returning to the same sites continually is key to providing the long-term care necessary for meaningful change. Returning to the same parks year after year allows us to build on our previous efforts ensuring that restoration and resilience work is not only effective but sustainable. This   helps us address the challenges posed by climate change while fostering more resilient ecosystems and park infrastructure. Ongoing stewardship also enhances park staff capacity to shift their focus to other areas of the park that need attention. This year, several parks will start new projects, which is made possible by the completion of projects in other priority regions or the need to expand existing restoration work that our volunteers have worked on. The flexibility to rotate focus across different park areas enables a more holistic and efficient approach to park management.

Wildfire Resilience


At China Camp State Park, volunteers will continue the important work of removing French broom and Scotch broom — highly invasive shrubs that threaten the park’s ecosystem. These aggressive plants are found throughout the park and require ongoing management to control their spread. Broom species outcompete native plants, reduce biodiversity, and increase wildfire risk due to their high flammability. These plants also alter soil chemistry, making it harder for native species to regenerate and thrive. Last year, efforts focused on Back Ranch Meadows, but this year, we’re shifting to a new site near Rat Rock Cove. While maintaining past project sites remains important, expanding to new locations helps prevent these invasives from establishing in other areas, ensuring a healthier ecosystem throughout the entire park.

Restoring Native Habitats


Several events will focus on restoring native habitats and promoting biodiversity.  At Half Moon Bay State Beach, our Earth Day project is part of an ongoing cycle of restoration work aimed at enhancing the area's resilience to sea-level rise and improving local habitats. Volunteers will help lay sheet-mulch to prepare areas for future planting and suppress invasive species from establishing and competing with the native plants. At Candlestick Point State Recreation Area, we are shifting our focus from previous events held in the main part of the park to the Last Port area. In this part of the park, . The native landscaping planted over 20 years ago  has been overtaken by invasive species. Volunteers will help restore the area by clearing invasive plants, such as fennel, to allow the now mature native shrubs, trees, and herbaceous plants to thrive. Their efforts will not only enhance the natural beauty of the site but also provide park interpreters with a more diverse array of native species to showcase to visitors.  

Last year, volunteers at Los Angeles State Historic Park planted native species to support pollinators like monarch butterflies and bees. This April, we’re inviting the public to learn about these efforts in a workshop with local experts, followed by a hands-on activity where volunteers will identify and mark native pollinator plants. These efforts will help raise awareness of local biodiversity to park visitors and highlight the impact of ongoing restoration.

Trail Maintenance


Crystal Cove State Park plans to restore Moro Overlook, a scenic spot with breathtaking views of the backcountry and coastline. Currently, it is overgrown with vegetation, lacks shade, and has been damaged by erosion caused by frequent off-trail use. When visitors stray from designated paths, they trample vegetation and compact the soil, reducing its ability to absorb water and making the area more vulnerable to erosion during winter storms. To make the overlook more accessible and enjoyable, volunteers will install directional signage and fencing to clearly mark the hiking trails, clear overgrown brush from the picnic area, and spread mulch for weed control. These improvements will help protect the landscape from further erosion and habitat damage while creating a more welcoming space for visitors. After volunteers complete this work, the park plans to install a shade structure and new picnic tables. With these new upgrades, staff will be able to use the area for educational programs such as school field trips and summer activities.

California State Parks Foundation’s annual Earth Day celebrations have taken place for more than 25 years. Cumulatively, these events have raised nearly $8.9 million, attracted nearly 93,000 participants, and resulted in more than 364,000 volunteer hours. By returning year after year, we build a stronger foundation for climate-resilient parks, ensuring that our efforts lead to sustainable, long-term progress. This year, we invite you to join the hundreds of volunteers that are expected to attend our events.
