 Thickets of saltwater paperbark are found where flood waters remain longest; stock watering bores have been established in these thickets and the watering troughs are used by waterbirds throughout the year.The most spectacular of the springs is Mandora Soak, a raised peat bog estimated to be 7000 years old.Some 269 species of vascular plants, from 55 families, have been collected from Mandora Salt Marsh.
