Original Blog Post

Surfrider has a longstanding commitment to preserving the coastline at Trestles. In collaboration with California State Parks and the San Onofre Parks Foundation, we're thrilled to announce monthly beach and habitat restoration events, offering you the chance to actively protect what you love.

These events will focus on removing invasive plant species identified by California State Parks, creating space for native plants and allowing Trestles' native dune habitat to flourish.

This work is crucial, as coastlines rich in native habitats are highly resilient to extreme weather and rising sea levels, ensuring enduring beaches for all to enjoy.

Join us in supporting the natural beauty and accessibility of Trestles for generations to come!



FAQ

Q: Will this restoration close the beach?

A: Not at all! Trestles will stay open to the public during these restoration events and beyond.

These efforts are all about restoring the natural balance of plants and habitats, ensuring sandy beaches and pristine waves for everyone to enjoy—today and for generations to come.

Q: How does this affect people visiting Trestles?

A: In the short term, there won’t be any changes to your time at Trestles—whether you’re surfing, hiking, or simply enjoying the beach.

In the long term, these restoration efforts will strengthen Trestles’ resilience to erosion and sand loss, enhance its already protected ecosystem, and might even offer even more epic views in the future!

Q: What's the big deal with native plants anyway?

A: While many plants may thrive in an area, not all allow an area to thrive.

Native plants are the unsung heroes of our ecosystems. They’ve evolved alongside local landscapes and wildlife over thousands of years, creating a harmonious balance that supports the health of wildlife and integrity of the terrain.

In contrast, invasive plants—those that aren’t naturally found in the area—can quickly dominate, outcompeting native species and depriving local wildlife of essential resources. Even worse, some invasive plants alter the soil structure, leaving areas more vulnerable to accelerated erosion. By restoring native plants, we’re helping ensure that Trestles thrives as a resilient, balanced, and vibrant ecosystem.

Q: These plants have been here as long as I can remember? Why remove them?

A: Even if a patch of plants seems contained, plants are designed to spread. Invasive species can extend their reach underground for hundreds of feet or release seeds that travel far via wind and waterways.

The problem is that invasive plants don’t just stay put—they can overtake other areas, disrupting local ecosystems. The best way to prevent our coasts from being overrun by any one species is through thoughtful management of what’s already growing.

Q: Can I help with the restoration effort?

A: Absolutely! These events are open to everyone and will occur monthly outside of the summer months. Be sure to visit our registration page for up-to-date information on event times and details.



Surfrider is proud to continue our long legacy of working hard to protect Trestles, and we’re excited to see you on the sand!
