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
In a new blog series, our Conservation Trainee Abi David explores some of the amazing creatures that call seagrass meadows their home. The small spotted catshark (Scyliorhinus canicula) is a small shark species growing up to 1 meter long and can be seen around European and North African coastlines. They
In an article for Halloween, Grace Cutler, one of Project Seagrass’ Interns for the 2025-26 academic year, explores the frightening reality of continued seagrass loss as a result of anthropogenic activity and how this in turn threatens seagrass’ role in supporting people and planet. Werewolves are struck down by silver
In a new blog series, our Conservation Trainee Abi David explores some of the amazing creatures that call seagrass meadows their home. The snakelocks anemone is a funny looking creature commonly found around the UK. They have up to 200 long, wavy tentacles and can grow on average to about
The Ocean is in crisis. Coral reefs are bleaching, seagrass meadows are vanishing, mangroves are being cleared, and biodiversity is plummeting. Scientists estimate we’ve already lost up to 50% of global saltmarshes, 35% of mangroves, and 20% of seagrasses. Yet alongside this sobering decline, momentum for marine restoration has never
Earlier this year, the Scottish Government circulated a draft version of Scotland’s first Blue Carbon Action Plan with key stakeholders to gather comments and feedback. Project Seagrass was one of the organisations contacted as part of this process. The Blue Carbon Action Plan sets out the Scottish Government’s position and
Posidonia seagrass meadows, veritable underwater forests, play a major ecological role. Under constant pressure from human activity, scientists are looking for ways to ensure their survival, in particular by carrying out restoration campaigns. A study conducted by the University of Liège at the marine and oceanographical research station STARESO (Calvi,
