These eelgrass seeds are fresh from the sea.
Mexico’s indigenous Comcáac people have managed to protect 96% of the precious eelgrass that grows in their region.

I have long known about beach grass and how it can hold the dunes and protect the land in a hurricane. I know about how easily the roots die if you walk on beach grass and why, when “Keep Off the Dunes” signs aren’t obeyed, houses wash away.

But I’m learning there’s another fragile grass that helps the environment. This one lives in the sea and captures carbon.

Sam Schramski has the story at Public Radio International’s the World.

“At a two-day festival on the coast of northern Mexico [last] month, scientists, chefs and local residents gathered to celebrate eelgrass — a unique type of seagrass that grows in the Gulf of California. 

“Seagrass is on the decline in the world’s oceans, but the Indigenous Comcáac people who live in the region have managed to protect the eelgrass that grows in their waters. 

” ‘From my parents, I learned about medicinal plants and the songs of plants, as well as about traditional foods,’ said Laura Molina, who is Comcáac.

“She remembers how her mom made tortillas out of flour ground from eelgrass seeds known as xnois in Comcáac language, a mix between wild rice and nori seaweed. 

Seagrass is getting a lot of attention these days because of its capacity to store carbon, estimated to sequester up to half the so-called ‘blue carbon’ in the world’s oceans and coastal ecosystems — putting it on par with global forests.

“Ángel León, a Spanish chef and owner of Aponiente restaurant, has made it his personal mission to protect threatened seagrass beds off the Spanish coast. He’s interested not only in the plant’s environmental benefits but also its culinary potential in the kitchen as a nutrient-rich superfood. …

“Seagrass is down about 30% globally since the late 1800s. Through León’s restaurant and related nongovernmental organizations, he has heavily financed seagrass restoration projects.” More at the World, here. Listen to the audio version there.

Kendal Blust at Fronteras also wrote about the festival: “In the small Comcaac village of Punta Chueca, on the Sonoran coast of the Gulf of California, a group of women gathered around a white sheet piled high with dried zostera marina, or eelgrass.

“One woman sang an ancestral song dedicated to the plant, known as hataam, as others beat the dried eelgrass and rubbed it between their palms to remove its small, green seeds. Xnois, as the seeds are known in the Comcaac language, cmiique iitom, are an ancestral food.

“ ‘The Comcaac are the only people, the only Indigenous group, that consumes the seed,’ said Erika Barnett, a Punta Chueca resident who has been heavily involved in restoration efforts.

“Eelgrass seed has been a part of their culture for millennia, she said. Traditionally, the flour was used to make tortillas and a hot drink combined with honey and sea turtle oil. And because it’s quite filling, it used to be carried by Comcaac during sea journeys. …

“Barnett said her great-grandparents were probably the last members of her family to collect and eat the xnois seeds. Her father, now 76, last tasted it when he was just 7.

” ‘That’s was the last time he ate it,’ she said. ‘It’s very ancient, but it’s no longer eaten like it used to be, and most younger people have never tasted it. So this effort is really rescuing our culture.’ …

“Now, Barnett is part of a team working to bring the tradition back to their community — both because of the plant’s nutritional value and its ecological benefits. Eelgrass creates habitat for sea turtles and fish, protects the coastline and captures carbon.

“ ‘It’s important for us to revive these traditions so they can be passed on to future generations,’ she said. ‘But I think we need to show the community that it can be done, first. That it’s hard, but we can harvest the seeds.’

“So for weeks in April, a group of women and girls harvested eelgrass the way their ancestors would have. They waded into the sea to collect plants floating near the shore, then dried, thrashed and winnowed them. …

“ ‘One of the missions of Aponiente is to look to the sea with hunger,’ said Greg Martinez, a chef and biologist. … Martinez said the restaurant is committed to discovering the gastronomic potential in the ocean, both for our health and for the planet.

“And eelgrass has a lot of potential. For one thing, it captures and holds carbon below the water’s surface. Known as blue carbon, it can help mitigate climate change.

“ ‘But it doesn’t only sequester carbon,’ Martinez said. ‘It also protects coastlines. It serves as a habitat for thousands of different species that come to breed in their protection. It buffers waves so if you have a tsunami or another storm it protects the coastline in that way as well.’

“Despite the swath of ecosystem services seagrasses provide, however, seagrass beds currently are disappearing from the world’s oceans, he said. And that makes it especially important to protect the abundant meadows in the Canal del Infiernillo, a channel between the coast and the massive Tiburon Island that is entirely within Comcaac territory.”

The radio show Living on Earth (LOE) reported recently on work to restore seaweeds that are a key part of the ecosystem.

From the LOE website: “Ripped from the seafloor by strong swells, massive amounts of kelp recently washed ashore in southern California. But the uprooted algae may actually be a sign of successful kelp restoration efforts. Marine biologist Nancy Caruso discusses the fragile ecosystem and how she and a community are helping to rebuild the majestic kelp forests.”

Radio host Steve Curwood interviewed Caruso. She recounts how she began 12 years ago with a group of students and volunteers “to restore the kelp forests off of Orange County’s coast.”

After a storm, she says, big holes get ripped in the forest of kelp, often 10 feet high. Then “new life can grow from the bottom up, and so if we see this happen, which we’re seeing right now, the kelp returns immediately after this event, then we know that our restoration efforts are successful, and after 30 years of our local ecosystem not having healthy kelp forests, we can rest assured that it’s now restored.”

To Curwood’s question about how restoration is done, Caruso answers, “It was actually quite an effort because I had the help of 5,000 students from ages 11 to 18 as well as 250 skilled volunteer divers, and we planted this kelp in 15 different areas in Orange County. There’s a spot down in Dana Point. It’s the only kelp forest that was left in Orange County so we would collect the reproductive blades from those kelp plants, and I would take them into the classrooms for the students to clean them and we would actually stress them out overnight. We would leave them out of water in the refrigerator, kind covered with paper towels, and then the next morning we would put them back in the ice-cold seawater and the kelp blade would release millions of spores” that would then be raised in nurseries and returned to the ocean.

“All those animals that get washed up on the beach inside the wrangled tangled kelp become a food source for shorebirds that live along our coast.”

Kelp forests can be seen along much of the west coast of North America.

An editorial in the NY Times earlier this month praised the efforts of a Long Island organization committed to rescuing a lovely, endangered body of water.

The editorial said that in Shinnecock Bay, “pollution from fertilizer and septic runoff feeds frequent algae blooms that block oxygen and sunlight. …  Once-lush beds of eelgrass, shelter for the little fish that feed bigger ones, have largely disappeared from the western part of the bay.”

But there is hope. “What Shinnecock Bay has going for it are scientists working to restore its waters and tidal flats to health. The Shinnecock Bay Restoration Program, run by Stony Brook University’s School of Marine and Atmospheric Sciences and its Institute for Ocean Conservation Science, means to fix the problem, not just study it.

“The institute’s executive director, Dr. Ellen Pikitch, said a big part of the job was as simple as replanting eelgrass and seeding the bay with clams and oysters, which filter the water clean and make the bay better able to fend for itself. …  Local officials were doing their part by agreeing to close sections of the bay to shellfishing.”

More on what is being done now and ideas for even bigger efforts here. The program could serve as a model for sustainability elsewhere in the world. And we can all do our bit by using less fertilizer and thinking first before putting pollutants down our drains.
