Seagrass Meadows: Marine Habitat Welfare and Conservation
Seagrass meadows support enormous marine biodiversity including seahorses, turtles, and dugongs, but are declining globally due to coastal development, pollution, and warming seas.
Key Facts
Seagrass meadows cover 300,000 km2 globally and support 20% of the world largest fisheries
Seagrasses are declining at a rate of 7% per year globally
Dugongs depend almost exclusively on seagrass for food and cannot survive without healthy meadows
Seagrasses capture carbon at 35 times the rate of tropical rainforests per unit area
UK seagrass restoration projects have successfully reestablished meadows through seed planting
Welfare Considerations
The loss of seagrass meadows has direct welfare consequences for the animals that depend on them. Dugongs face starvation as food sources disappear. Sea turtles lose critical feeding grounds. Fish and invertebrate species that complete life cycle stages in seagrass habitat face reproductive failure. Seagrass conservation is simultaneously a welfare and ecosystem health intervention.
What You Can Do
Support seagrass restoration programs financially and through advocacy
Reduce fertilizer and chemical runoff from gardens and farms near coastal areas
Choose sustainably caught seafood to reduce trawling damage to seagrass beds
Donate to marine habitat conservation organizations working on seagrass protection
Advocate for coastal development setbacks that protect seagrass meadow habitats
