Keeping you up to date with Project Seagrass news and views with a mixture of field notes and commentary on seagrass and marine conservation topics.
Discussions of valuable but threatened ocean ecosystems often focus on coral reefs or coastal mangrove forests. Seagrass meadows get a lot less attention, even though they provide wide-ranging services to society and store lots of climate-warming carbon. But the findings of a new University of Michigan-led study show that seagrass
Mangroves are growing in areas historically dominated by salt marshes and oyster reefs. Invasive pacific oysters are replacing native blue mussels in the Wadden Sea. Macroalgae are exhibiting dominance over hard corals in the Caribbean and Indo-Pacific. Climate change-driven shifts in dominant, habitat-forming species such as these can have significant
Seagrass, a group of aquatic angiosperms, grows in shallow waters in the coastal sea and contributes most of the primary production while participating in many important ecological processes. Heat stress threatens the survival of seagrass, but its damage mechanisms are unclear. Recently, a research team led by Prof. Liu Jianguo
A study of eelgrass meadows planted by researchers from the University of Gothenburg shows that fauna return rapidly once the eelgrass has started to grow. Already after the second summer, the biodiversity in the planted meadow was almost the same as in old established eelgrass meadows. Eelgrass meadows have declined
In Florida alone, thousands of acres of marine seagrass beds have died. Major seagrass die-offs also are occurring around the world. Stressors such as high temperature, hypersalinity and hypoxia or lack of oxygen affect seagrasses’ ability to resist and recover from these stressor-related mortality events or when disturbances lead to

Storm Garry March 1st marked an important date in seagrass history as globally we celebrated the very first World Seagrass Day, formally recognised by the United Nations! This day will continue to annually raise awareness of the importance of healthy seagrass meadows. Seagrass is the only marine flowering plant in
Eva Rothausler On a narrow stretch along the northern-central coast of Chile, the seagrass Heterozostera nigricaulis (syn. Zostera nigricaulis, Heterozostera tasmanica) occurs in three isolated patches no more than 300 km apart. It is a common intertidal to subtidal seagrass in the Zosteracea family and is found growing in protected
As our Fragment Walks from the 2025/26 season come to an end Project Seagrass Intern Anya Lamparelli reflects on this year’s efforts. A seagrass fragment is a precious and vulnerable thing. Torn free by winter storms and strong swells these delicate shoots with intricate root systems still attached wash ashore
A new study of the British Isles’ coastal ecosystems has revealed that nitrogen enrichment is significantly reducing the abundance and variety of marine life. The research, published by scientists at Swansea University and the charity Project Seagrass, warns that increasing nutrient flows are overriding local habitat conditions to restructure and
Residents and visitors to the Isle of Wight can now access information about the Island’s important seagrass habitats thanks to new signage installed through support from Seacology. The signage has been installed by Project Seagrass as part of ongoing efforts to protect and restore seagrass ecosystems within the Solent. The signs
Hannah Harrero and Stephanie Insalaco-Wyner, geographers from Florida, comment on differing methods of monitoring the resilience of seagrass meadows in Florida’s ‘Mosquito Lagoon’, following a number of extreme weather events. Florida’s Indian River Lagoon has been an ecosystem in decline going back to 2011, when harmful algal blooms led to a severe decline in
Heidi McIlvenny, PhD researcher from Queen’s University Belfast, comments on seagrass meadows in Northern Ireland and how seagrass meadows can recover but only if we tackle the pollution at its source. I spent last summer wading through seagrass meadows across Northern Ireland, from the sheltered waters of Strangford Lough to
Between the 17th and 23rd March 2026, members of the Project Seagrass team were on the Isle of Wight carrying out active restoration as part of the The Solent Seascape Project, the first project of its kind in the UK to initiate seascape-scale restoration. As part of The Solent Seascape
