Seagrass production around artificial reefs is resistant to human stressors

Artificial reefs might help to restore the ocean’s ability to fight against climate change. The reefs boost the productivity of seagrass meadows by attracting fish, which can improve the ability of these habitats to lock up more carbon dioxide beneath the waves. Breeze blocks placed in one of the ocean’s most endangered habitats provide an unexpected lift for fish. Seagrass meadows are found across the world, reaching from the tropics up into the lower reaches of the Arctic circle. They are incredibly valuable habitats, providing a nursery for young fish as well as sucking vast quantities of carbon dioxide from…

Caribbean seagrasses provide services worth $255B annually, including vast carbon storage

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 ecosystems deserve to be at the forefront of the global conservation agenda, according to the authors. It's the first study to put a dollar value on the many services—from storm protection to fish habitat to carbon storage—provided by seagrasses across the Caribbean, and the numbers are impressive. Using newly available…

Fauna return rapidly in planted seagrass meadows, study shows

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 heavily in southern Bohus county in recent decades and in many places have disappeared altogether. Researchers at the University of Gothenburg have been working on the restoration of eelgrass meadows for twelve years. These meadows are important for biodiversity, as the eelgrass serves as habitat or nursery for young cod,…

Seagrass crucial to stemming the tide of coastal erosion

The sea devours large tracts of land when storms wash sand out to sea from the coast. A new study involving a researcher from the University of Gothenburg has shown that seagrass can reduce cliff erosion by up to 70% thanks to its root mats binding the sand. Coastal erosion is a global problem that is often combated by replenishing the coast and beaches with new sand in locations where storms wreak the greatest havoc. According to a 2016 survey conducted by the Geological Survey of Sweden, 12% of Skåne's coastline in southern Sweden is vulnerable to increasing rates of…

Why saving the world’s seagrass is part of the most important to-do list in the history of humankind

“The downward trajectory of the world's seagrass meadows must be reversed if we are to fight the planetary crisis” say leading seagrass scientists. School of fish in the seagrass, Komodo, Indonesia. (Credit: Matt Curnock / Ocean Image Bank) The United Nations Sustainable Development Goals have recently been described as “the most important to-do list in the history of humankind”. Scientists from Project Seagrass and Swansea University have this week published a unique review that demonstrates how this “To-Do List” of Sustainable Development Goals provides a blueprint for achieving the net recovery of seagrass ecosystems. Conserving and restoring seagrass meadows contributes…

Seagrass meadows are reliable fishing grounds for food

A new study shows that seagrass fisheries provide a reliable safety-net for poor fishermen, since they perceive those habitats to maintain large fish catches over time. Surprisingly, even more so than coral reef fisheries, which people normally associate with small-scale fishery. Seagrass meadows are routinely used as a fishing habitat across the Indo-Pacific region to sustain millions of households by providing fish and other animals for food and income from fishing. A new study in Ocean and Coastal Management investigated how and why households use seagrass meadows across Cambodia, Tanzania, Sri Lanka and Indonesia in the Indo-Pacific region by conducting…

A Glimmer of Hope for Seagrass in the Wakatobi National Park?

Back in December 2015 I spent a couple of weeks in the Wakatobi, Indonesia, initiating phase II of the Wakatobi Seagrass Program. This seeks to build on work carried out though a previous project “Recognising the role of seagrass meadows in food security: re-prioritising the marine conservation agenda” (2011-2014), which was conducted in the same location. That project evidenced the direct economic value and food security potential of seagrass meadows and prompted local government and community stakeholders to place seagrass on their conservation agendas for the first time. The Wakatobi project demonstrated how seagrass associated species provide an essential source…

Puttalam Lagoon – Paradise Lost?

At the end of August I spent 10 days conducting fieldwork in Pattalam Lagoon, which is situated in the north west of Sri Lanka. The purpose of my visit to Puttalam Lagoon was to set up socio-economic and fish landings surveys with a research collaborator, who will now complete the surveys. This research was undertaken to contribute to a growing database covering South East Asia and beyond, linking seagrass meadows and food security, by using Sri Lanka as a case study. The lagoon was fringed with seagrass meadows and populated by many dense mangrove islands. Before the trip, I had…
