Nathanson Creek Preserve

History of our work at Nathanson Creek Preserve

Nathanson Creek, which runs north-to-south through the middle of the City of Sonoma, was once a beautiful waterway. But it had deteriorated over the years due to pollution and neglect, and by the late 1990s was little more than a runoff ditch. That’s when Sonoma Ecology Center, with help from partners Ag + Open Space, Sonoma Water, and the City of Sonoma began leading clean-up and restoration efforts along its banks.

Today, Sonoma Ecology Center manages the ecological health of Nathanson Creek Preserve through contract with the City of Sonoma. The Preserve is a beautiful and thriving greenway, accessible to the public by bridges and walking trails. Its waters are cool and clear again, allowing Chinook salmon to return to spawn.

The Nathanson Creek Preserve hosts a native plant demonstration garden to educate the public on the benefits of plants and provides habitat for pollinators.

Across MacArthur from the demonstration garden, the north end of the preserve has a new feature: the Nathanson Creek Preserve Flood Plain, which helps to manage flooding, provides valuable habitat, and in springtime bursts with poppies and other flowers.

This city jewel in the heart of downtown is located alongside Sonoma Valley High School and Adele Harrison Middle School. Both use Nathanson Creek as a living outdoor classroom. Meanwhile, local gardening enthusiasts volunteer their time to keep the demonstration garden and their local community flourishing.

At the corner of 2nd St. East and East MacArthur, a native plant demonstration garden entices, delights and educates passersby on native plant species while providing a habitat for native pollinators.

After the storm on January 9, SEC’s Restoration Team installed a Nathanson Creek Oxbow, which is working at intended, as shown in this picture.
