Seagrasses are a foundational element for coastal ecosystems worldwide, removing nutrients, CO2, pathogens, and even heavy metals from the water column to support abundant marine life. Roughly a fifth of the world's seagrass has been lost since the late 1800s, making restoration central to ocean stewardship. A major constraint on scaling seagrass restoration is access to planting material. Traditionally, divers collect plants from the seabed or gather seeds by hand. It is slow, labor-intensive work that cannot scale with conventional methods. Harvesting plants from donor meadows can even damage the healthy habitats that restoration is meant to protect. Ulysses is developing minimally invasive, species-specific payloads that collect fruits and seeds at scale from key seagrass species, including Posidonia australis, Zostera marina, and more. Automating collection cuts cost and reduces disturbance to donor meadows, so we can restore larger areas while protecting existing habitat.
