European herring gull
In the dunes we find common hawthorn, the common sea-buckthorn, honeysuckle; on the marshes sea lavender, sea wormwood, sea aster and glasswort. On the whole island lichens and mushrooms can be found, as well as many species of insects. On the marshes and tidal flats thousands of birds occur, such as common redshank, barnacle goose, spoonbill, hen harrier, oystercatcher, red knot, bar-tailed godwit, curlew and European herring gull. In the past the rabbit was very common, but because of the rabbit haemorrhagic disease (RHD), the species is rare now.
