Help Santiago Creek Greenway Alliance remove crown daisy from Santiago Creek at the east end of Hart Park (Shaffer Street immediately south of La Veta) this Saturday at 8am (2 hour duration). Using hand clippers, we will cut the plant at its base snipping off and bagging its seed heads and leaving the rest of the plant to decompose in the creek bed. Although crown daisy with its showy, yellow flowers is attractive, it is a highly invasive plant which many land managers in Orange County work to keep out of waterways.

Please wear closed-toed shoes, gloves, long pants, hat, and sunscreen. Also, bring water and (if you have them) hand clippers or scissors.

It was an outstanding collaborative effort in celebration of Earth Month this Saturday morning.

More than 50 volunteers came together to remove over one ton of trash from the Santiago Creek area below Grijalva Park.

We extend our sincere thanks to the Orange High School ROTC, Chapman University, UC Irvine, Scout Pack 850, Orange Sustainability, Naturalist For You, Hiking On Purpose, Mayor Dan Slater, We Explore Earth, and the City of Orange for their partnership and support.

These dedicated groups joined the Santiago Creek Greenway Alliance for our monthly cleanup, demonstrating the power of community in preserving our local environment.

We invite you to join the Santiago Creek Greenway Alliance as we continue our efforts at Yorba Park next month, Saturday, May 9th, for our next cleanup event.
