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.
Seagrasses evolved from freshwater plants and use sunlight and carbon dioxide (CO2) for photosynthesis and are able to thrive in depths down to 50 meters. In contrast to algae, they possess roots and rhizomes that grow in sandy to muddy sediments. The grass-like, leaf-shoots produce flowers and complete their life
For approximately 3,000 years, generations of green sea turtles have returned to the same seagrass meadows to eat. This was discovered by Willemien de Kock, a historical ecologist at the University of Groningen, by combining modern data with archaeological findings. Sea turtles migrate between specific breeding places and eating places
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

Earlier this year, Project Seagrass launched a creative competition in collaboration with our official patrons, Coldplay. The competition invited entrants to submit inspiring, impactful, and creative designs communicating one of the following five themes: 1. The importance of seagrass 2. Seagrass and people 3. Seagrass around the world 4. Seagrass
Seaweed farming is a rapidly expanding global industry. As a food resource, it has high nutritional value and doesn’t need fertilisers to grow. Seaweed provides valuable habitats for marine life, takes up carbon and absorbs nutrients, plus it helps protect our coastlines from erosion. Usually, seaweeds grow on hard, rocky surfaces. Yet, to
A new QR code on the Wales Coast Path at Porthdinllaen and Morfa Nefyn reveals the story of the large seagrass meadow in the shallow water. Thousands of people visit this area every year to enjoy its natural beauty, but few are probably aware of the seagrass meadow – estimated
Eelgrass, a type of flowering seagrass found in temperate zones around the world, provides habitat for many species, protects coastlines, improves water quality, sequesters carbon and supports fishing economies. The foundation of a highly productive marine food web, eelgrass’s health is paramount but mysterious. Scientists have long studied how terrestrial
Scientists have warned efforts to protect and restore marine habitats along the UK’s coastline could be hindered by a lack of public knowledge about these initiatives. In the face of climate change and rising sea levels, nature-based coastal solutions (NBCS) are emerging as a sustainable and environmentally friendly way to
Gathaagudu/Shark Bay is located on Malgana (pronounced Mal-guh-nuh) Country. It’s a place of great natural beauty and a UNESCO World Heritage Site. The landscape is a stunning array of colors as the desert meets the ocean. Below the sea’s surface, 4,000 square kilometers of seagrass meadows sway. That’s equivalent to
