Kelp is common along temperate shorelines around the world. For millennia, this large brown algae has been vital to coastal Indigenous peoples. In Washington State and British Columbia, kelp is a traditional food source, a focus for commercial cultivation, and habitat for critically endangered and threatened species like rockfish and young salmon. It’s hard to overstate kelp’s value.
Begun in 2010 by researchers at the University of Wisconsin–Milwaukee, the existing seed bank houses a collection of bull kelp spores from the Washington coast. Currently, the spores are housed in Wisconsin, but in the coming months, the collection will be moved to a US National Oceanic and Atmospheric Administration Fisheries research station in Manchester, Washington.
Unlike with many terrestrial plant seeds, which can be dried and stored for decades and remain viable, storing kelp for extended periods is more complex. To reproduce, explains Raymond, kelps release zoospores that develop into male and female gametophytes. To keep them viable, scientists store kelp gametophytes under red light, in low iron environments, or in a freezer, which puts it in a kind of arrested development.
“The gold standard for restoration is to replicate what was lost in the place where it was lost,” says Toft. Raymond hopes restoration in the future won’t be necessary. But if it is, and all goes as planned, “even 50 or 100 years in the future” the Jamestown S’Klallam Tribe will be able to access the seed bank.
