Oysters find new home in Presidio tidal marsh; project aims to adapt infrastructure to climate change

SAN FRANCISCO (KGO) — A project alongside the San Francisco Bay is merging structure with wildlife conservation.

Wildlife ecologist Jonathan Younger, is sloshing into the waters of the Presidio’s latest tidal marsh, to see the distinction a 12 months makes for the reason that project started.

His focus, oysters, now making themselves at home in a wide range of prefabricated pods and panels put into service starting final November.

“The goal again is to maximize oyster recruitment, so get them to come and settle on to these panels and grow,” Younger explains.

The project basically started with the opening of Quartermaster Attain. It is a restored tidal marsh, stretching inland from the sides of Crissy Discipline and related by a culvert system, permitting salty Bay tides to combine with a historic freshwater stream.

Younger confirmed off raised panels briefly eliminated for inspection throughout a latest dive. Just like the dome-shaped pods positioned in the marsh itself, the panels present the native Olympia oysters with a home to connect themselves to alongside the cement partitions of the culvert.

“Oysters, oysters, oysters, oysters, all those are oysters,” he says fortunately pointing to the small round oysters connected to the panel.

The oyster introduction is definitely an ongoing experiment, not simply in city ecology, however design evolution and the best way we adapt our cities and shoreline to climate change. The textured fiberglass panels had been specifically designed, created with the assistance of Evan Jones and Margaret Ikeda, and designers from the California Faculty of the Arts.

“I thinks it’s part of a very new way of thinking about infrastructure design and ecology together,” says Jones.

And Ikeda believes quite a few initiatives across the Bay may gain advantage.

“You know, the San Francisco seawall, while they’re going to be protecting both airports, the Port of Oakland is looking for different strategies. So this kind of work definitely informs,” she says.

Younger says the Presidio group continues to be studying in regards to the physics of the tidal marsh, which areas the oysters will thrive in and what different species is perhaps benefiting together with them. And as renovation initiatives proceed alongside Crissy Discipline, the marsh will evolve as a form of a residing petri dish, doubtlessly giving ecologists and engineers revolutionary designs that may be duplicated round San Francisco Bay.

“Things are changing and we need to adapt, and it’s unknown. So these are opportunities to use science to advance our knowledge,” says the Presidio’s Younger.
