Australia’s Great Barrier Reef is renowned for its coral, but far less so for its expansive seagrass meadows. “People don’t dive on them, don’t snorkel on them, and don’t go rock pooling on them,” said Emma Jackson, director of the Coastal Marine Ecosystems Research Centre (CMERC) at Central Queensland University. She’s a self-confessed seagrass nerd. One reason, she said, is because “they have this wealth of different ecosystem services.” Though they’re known as the “ugly cousins” of coral reefs, these flowering grass-like plants provide a home and foraging grounds for marine life, as well as habitat for commercial fish species. These meadows stabilize sediments, help cleanse the water column and sequester substantial amounts of carbon. “I think when people understand that, then they can share my nerdiness and share that passion for seagrass,” Jackson said.

The Great Barrier Reef is home to around 3.5 million hectares (8.6 million acres) of seagrass, an area larger than Belgium, which accounts for about 11% of the world’s total. Australia is a global hotspot of seagrass biodiversity, hosting around half of the world’s 60 species of the plants. But as climate change ratchets up temperatures and triggers more frequent extreme weather events, Australia’s marine meadows are increasingly battered by intense storms and cyclones, flooding, and devastating marine heat waves. Algal blooms are also impacting seagrasses by blocking out sunlight…This article was originally published on Mongabay
