San Francisco Estuary Invasive Spartina Project


Thank you for reporting the card you found!
Just fill out the brief form below.

Thank you for going to our website to report where you found a "drift card."

The Invasive Spartina Project (ISP) has released these drift cards to learn more about how the currents of the Bay may carry seeds of an aggressively invasive plant, a type of cordgrass (Spartina), to new areas. By reporting where you found this drift card you will help us to know where to survey for new invasive Spartina locations. This will help us to successfully eradicate this introduced plant.

Learn more about our drift card study and impacts of invasive Spartina.

ALERT! Please do not throw the drift cards back into the Bay! This could confuse our study results. You may keep them or otherwise dispose of them
