Scientists in Croatia are working to protect Posidonia seagrass

Scientists on the Croatian island of Dugi Otok in the Adriatic Sea have conducted a dive mission to assess damage caused by human activity. They are demanding that action be taken to protect the environmentally important seagrass meadows.

Posidonia Oceanica, also known as Mediterranean Tapeweed, is named after Poseidon the Greek god of the ocean. It provides food and shelter to fish, protects the coasts from erosion and purifies the water.

Scientists have found that a meadow of Posidonia could absorb up to 15x more carbon dioxide annually than a piece of Amazon rainforest of similar size.

Scientists say that much more must be done to protect the area from tourists anchoring in the Adriatic Sea and from trawlers pulling fishing nets through the water of the Adriatic Sea near Dugi Otok, and the Kornati archipelago National Park.

They have called for stricter regulations, and fines on those who break them.

Dominik Mihaljevic is a biologist in the national park. He said that the park has begun installing anchorages which will not harm seagrass.

He said that the ultimate goal was to prohibit anchoring in all 19 of the anchorage sites currently used.

Matea Spika is a senior associate with Croatia's Sunce association for environmental protection. She told me that Mediterranean Posidonia endemic to Mediterranean Sea has declined by 30% over the past 30-40 years.

She said that in addition to the anchors and nets issue, chemicals, excess nutrients coming from cities and farms, warming waters caused by climate change, invasive species, and excessive nutrients coming from farms had also caused damage.

Posidonia is also unable to grow because of artificial beaches and new ports. (Reporting and Writing by Aleksandar Vaovics, Editing by Barbara Lewis. Reporting by Antonio Bronic)
