What do a healthy atmosphere, endangered wildlife, and coastal infrastructure all have in common? You might drive by it without a second thought, but the San Diego River Estuary in Ocean Beach works around the clock to protect all these features and more!
Estuaries, where freshwater rivers mix with the ocean, are known to bring a plethora of benefits to nearby communities. They absorb excess floodwater, serve as habitats for animal life, and even filter out dangerous pollutants. As Coastal Blue Carbon reports, estuaries store away nearly 3 billion tons of carbon dioxide in the continental US alone!
Even compared to other estuaries, however, the preservation of San Diego’s wetlands is of the utmost importance. The biome acts as home for a whopping 137 documented species of birds – many of which, such as the California least tern and western snowy plover, are endangered or otherwise threatened. The San Diego River Estuary also represents a significant portion of our community’s only remaining wetlands.
A report by Rewilding Mission Bay found that only 1% of Mission Bay’s estuaries remain, and that the state of California has lost 91% of these crucial environments over the years. Despite its scarcity, the estuary is at a continuous risk of damage every single day. Trash and pollution endanger local wildlife, toxicate the water, and present a public health hazard. Likewise, off-trail hiking and dog-walking can trample plants and bird nests, causing additional harm to the precious ecosystem.
It is for this exact reason that volunteers at the San Diego River Park Foundation (SDRPF) are hard at work in Ocean Beach! For over 20 years, the community has come together to care for and restore the estuary – whether it be through weekly small group habitat restorations or other larger events. One popular example is SDRPF’s annual Kayak Cleanup, which not only provides OB residents with a unique recreational opportunity, but also helps to remove trash stuck in estuary vegetation. By targeting such waste hotspots, the team has been successful in preserving protected aquatic habitats. In the past year alone, 240,485 lbs of trash were prevented from reaching the ocean!
To protect critical estuary ecosystems, SDRPF’s Estuary Trail Stewards group is also leading efforts to restore habitats, install protective fencing, and enhance signage to guide visitors along designated paths. By directing foot traffic away from sensitive nesting and foraging areas, SDRPF aims to minimize human impact while allowing the community to enjoy the estuary responsibly. Forming a balance between recreation and conservation is key to this relationship – by implementing guided nature walks and stewardship training sessions, the Estuary Trail Stewards team works to provide community members with the knowledge and tools to actively participate in preservation. These efforts aim to foster a sense of ownership and responsibility for the estuary, turning visitors into long-term guardians of this unique habitat!
“Caring for the San Diego Estuary means safeguarding the native species that depend on it. My passion for this river drives me to protect and restore its habitat, ensuring that future generations can experience the same thriving ecosystem that has inspired me,” said Hayden Huff, a dedicated Trail Stewards volunteer.
SDRPF aims to reimagine the San Diego River as a natural, cultural, recreational, and accessible treasure. Through organized events, people of all ages and abilities can participate in activities vital for the river’s health and form a deeper connection with both fellow community members and the natural world! Ultimately, it is through such service that you can take small, simple steps towards real change.
You have the power to play a crucial role in these conservation efforts! Join us on the 2nd and 4th Tuesdays of the month from 8 am – 11 am (9 am – 12 pm starting 9/2) to make a difference for our precious estuary! Learn more and find volunteer opportunities here https://sandiegoriver.org/!
