How planting 70 million eelgrass seeds led to an ecosystem’s rapid recovery

In the world’s largest seagrass restoration project, scientists have observed an ecosystem from birth to full flowering.
As part of a 20-plus-years project, researchers and volunteers spread more than 70 million eelgrass seeds over plots covering more than 200 hectares, just beyond the wide expanses of salt marsh off the southern end of Virginia’s Eastern Shore. Long-term monitoring of the restored seagrass beds reveals a remarkably hardy ecosystem that is trapping carbon and nitrogen that would otherwise contribute to global warming and pollution, the team reports October 7 in Science Advances. That success provides a glimmer of hope for the climate and for ecosystems, the researchers say.
