THE DOWNLOAD: Floating, Decorating, Tasting

An island of plants is improving the water quality and habitat in the Arboretum Waterway, but it didn't appear there naturally.

The floating pad, described in the above video, was launched near Putah Creek Lodge by Arboretum and Public Garden Learning by Leading Waterway Stewardship interns.

The Arboretum Waterway — the lowest place on campus — is the catch-all for the stormwater runoff as well as the campus’s recycled water. As a result, the water is rich in nitrate and phosphate levels, which creates the perfect growing conditions for algae and duckweed during our warm summers.

“In the past, we have had issues of decomposing algae blooms, which result in low dissolved oxygen and potential fish kills in the Waterway,” said Nina Suzuki, waterway steward. “Our floating island will demonstrate the effectiveness of green solutions to water pollution. Installing wetland plants is a sustainable, energy efficient method for removing nutrients and increasing dissolved oxygen, which will improve water quality.
