Wild Dugong Welfare and Seagrass Conservation

How seagrass loss driven by human activities threatens dugong welfare and survival across Indo-Pacific waters.

Key Facts

Dugongs are classified as Vulnerable with fewer than 90,000 individuals remaining in warm coastal waters
They depend entirely on seagrass for nutrition — a single dugong can consume 40 kilograms of seagrass daily
Seagrass loss from dredging, coastal development, and runoff has eliminated dugong habitat across much of their range
Boat strikes cause significant dugong mortality and injury in areas where they share waters with marine traffic
Dugongs are slow-reproducing — females produce one calf every 3-7 years, making population recovery slow

Welfare Considerations

Dugong welfare is fundamentally determined by seagrass availability. As obligate seagrass grazers, habitat loss forces dugongs into nutritional stress with direct welfare consequences — individuals must travel further to find food, increasing energy expenditure and boat strike risk. Coastal development, runoff from agriculture, and dredging continue to degrade and destroy seagrass meadows across the Indo-Pacific. Recovery is slow even when threats are removed. Boat strikes impose acute welfare harm through traumatic injury and drowning from propeller strikes. Each individual dugong death has population-level significance given their extremely slow reproductive rate.

What You Can Do

Support seagrass restoration programs and advocate for coastal development setbacks that protect seagrass meadows
Slow down in dugong habitat and follow speed zone regulations in marine protected areas
Advocate for stricter coastal water quality standards that reduce seagrass-damaging agricultural runoff
