Report a Seagrass Sighting | Posidonia australis Flowers & Fruits

Report a Flower or Fruit Sighting

Understanding when and where Posidonia meadows are flowering and producing viable seeds is crucial. If we can identify those meadows, we can collect seeds and grow them in aquaria to support large-scale restoration efforts across NSW and beyond. If you spot Posidonia flowers or fruit, we'd love to hear from you!
