Estuary

Where river meets sea, some very distinct habitat types develope. Rivers carry masses of sediment towards the sea, and this sediment contains plenty of organic material that serves as food for marine plants and small animals – these in turn attract larger animals. The mudflats that form around sheltered estuaries are magnetically attractive to wildfowl and shorebirds, which can congregate in mindboggling numbers, and the birds of prey that come to hunt them. The mud teems with small burrowing animals, and the tidal reaches of the river, where fresh and salt water mingle, have their own specialised wildlife communities. The influence of the sea on the river and its wildlife can reach more than 100km inland. Many estuaries around Britain have lost some of their wildlife interest as a result of development, but nature reserves protect some key sites, and some estuarine areas are internationally important for their wildlife. Walking around wild estuaries can be hazardous because of the soft muddy ground, but they are magnificent landscapes, with their big skies and expansive mudflats, with vast flocks of waders and wildfowl circling above.

Cliffs & headlands So far we have looked at coasts where the land slopes gradually towards the sea. Cliff coasts are a dramatic contrast, the land looking as though its edges have been abruptly snapped off, leaving a near-vertical face of bare rock. This is not an easy environment for animals to live on, as there is little vegetation, and soft rock is highly likely to crumble and fall away. Yet cliff-faces can hold wildlife at mind-boggling densities – the great ‘seabird cities’ of cliff-nesting auks, Kittiwakes and other species are among the most impressive natural wildlife spectacles you’ll find in Britain, and are of great ecological importance on a world scale. The tops of cliffs are also interesting environments in their own right, particularly in terms of the flowers and invertebrates they support. Coastal headlands, which may or may not have cliff-faces, are of interest to those wanting to see scarce migrant birds, because they project out into the sea and offer first landfall to lost travellers.


Cliffs & headlands So far we have looked at coasts where the land slopes gradually towards the sea. Cliff coasts are a dramatic contrast, the land looking as though its edges have been abruptly snapped off, leaving a near-vertical face of bare rock. This is not an easy environment for animals to live on, as there is little vegetation, and soft rock is highly likely to crumble and fall away. Yet cliff-faces can hold wildlife at mind-boggling densities – the great ‘seabird cities’ of cliff-nesting auks, Kittiwakes and other species are among the most impressive natural wildlife spectacles you’ll find in Britain, and are of great ecological importance on a world scale. The tops of cliffs are also interesting environments in their own right, particularly in terms of the flowers and invertebrates they support. Coastal headlands, which may or may not have cliff-faces, are of interest to those wanting to see scarce migrant birds, because they project out into the sea and offer first landfall to lost travellers.
