The estuarine section of the Exmouth LNR is a good site to observe evidence of natural regeneration and ecological succession. The tidal mudflats are highly productive and the eel grass beds and invertebrates living in the mudflats provide a rich food source for the bird populations. The large eelgrass Zostera nolti beds are particularly notable. A nationally rare bristle orm Ophelia bicornis can also be found on the reserve.
