Dugong Welfare and Seagrass Loss

Dugongs are entirely dependent on seagrass meadows, making water quality degradation and coastal development direct welfare threats through food deprivation.

Key Facts

The dugong population in Torres Strait and northern Queensland numbers around 12,000
Dugongs consume up to 40 kg of seagrass daily and starve within weeks if seagrass is unavailable
Cyclone-driven turbidity and runoff from agriculture have caused seagrass die-offs in Moreton Bay and elsewhere
Indigenous communities in northern Australia have traditional hunting rights for dugongs
Boat strikes cause dugong deaths from propeller wounds and blunt trauma

Welfare Considerations

Seagrass-deprived dugongs starve slowly over weeks to months — strandings of emaciated animals represent the endpoint of prolonged starvation. Runoff from agriculture clouds the water that seagrass needs for photosynthesis. Dugongs struck by boats suffer traumatic injuries from propellers and keel impact. Their slow reproduction — one calf every 3-7 years — means individual deaths have significant population consequences.
