Ecology

The 4.43 square kilometres (1.71 sq mi) site covers a mix of coastal habitats, with areas of grassland, lowland heath, reed bed, shingle, dune and woodland. Rare shingle flora such as sea pea, sea kale, sea holly and yellow horned-poppy can be found at North Warren. Key conservation bird species found at the site include Eurasian bittern, European nightjar, nightingale and western marsh harrier.[1]

It is also an important over wintering site for wildfowl including large numbers of Eurasian wigeon, common teal and a flock of greater white-fronted geese.[2] In 2007, three marsh harrier chicks fledged from three nests and seven nightjars, 23 pairs of woodlark, seven pairs of Dartford warbler and three booming bitterns were recorded.[3]

Mammals found at the site include European otter, European water vole, European badger and European rabbit, and small numbers of red deer and muntjac can be seen. The reptiles adder, slow-worm and common lizard are present in heath areas, while the amphibians common frog, common toad, smooth newt and palmate newt can be found in wetland areas.[4]

Many insect species can be found at North Warren, with large numbers of dragonfly and butterfly in summer months (northern hemisphere), including the nationally rare silver-studded blue. In 2007, an invasive insect pest, the wheat bug Nysius huttoni, was found at North Warren for the first time in the UK. Originally from New Zealand the insect feeds on weeds and crop plants and has since been found at other sites in the UK.[5]

History

The original North Warren reserve comprising 37 hectares (91 acres) was purchased by the RSPB in 1939 due to interest in its breeding bird populations. In subsequent years the reserve has expanded as land has become available for purchase and now covers 443 hectares (1,090 acres). During World War II, pillboxes and trenches were constructed on the heath and tank traps were placed across the marshes as part of the British coastal defences.[4]
