Suffolk Coast & Heaths, AONB, TM177 349, 0 m


Stretching south from Lowestoft to the river Stour, the AONB protects heathland, reed beds, saltmarsh and mud-flats, a rich mixture of unique and vulnerable lowland landscapes, all of which are under pressure of change. It is deeply indented by the estuaries of the Blyth, Alde, Deben, Orwell and Stour and bounded by the crumbling cliffs and tidal spits of the low and lonely North Sea coastline, the nearest unspoilt coast to Greater London. Habitats of interest on the site include ancient open heathland, saltmarsh, mudflats, wetlands, shingle beeches and woodland.


Outer Thames Estuary, SPA,TR273 962, 11 m


Outer Thames Estuary SPA is a large marine area that is important for birds. The site supports 38% of Great Britain’s Gavia stellata (Red-throated Diver) population.


Newbourn Springs, SSSI, TM270 435, 273 m The major part of the site comprises a narrow spring-flushed valley occupied by a fast flowing stream with Alder carr and small areas of fen on peat overlying London Clay. Drier more acidic soils further west and above the stream valley support broad-leaved woodland, scrub, grassland communities and Pteridium aquilinum (Bracken) dominated heath. Active management has led to the maintenance of a rich and varied flora and the subsequent diversity of habitats attracts good populations of breeding and migratory birds. There is a diverse ground flora along the stream banks and beneath the woodland; species of note including Listera ovata (Common Twayblade), Dactylorhiza fuschii (Common Spotted Orchid) and Ophrys apifera (Bee Orchid). The steep valley side above the stream supports Oak-Ash-Hazel woodland which has grown up into high forest. Above the valley is a large area of Pteridium aquilinum (Bracken) dominated heath fringed by thorn scrub. Some areas have been cleared and patches of dry acid grassland and heather heath have developed. A variety of birds breed on the site including Luscinia megarhynchos (Nightingale), Regulus regulus (Goldcrest), Warblers and Woodpeckers. Migratory birds such as Sylvia Warblers and Turdus pilaris (Fieldfare) are regular visitors as are many butterflies including Callophrys rubi (Green Hairstreak) and Satyrium w-album (White Letter Hairstreak).


Alde-Ore Estuary, SPA, Ramsar & SSSI , TM396 491, 397 m


The site stretches along the coast from Bawdsey to Aldeburgh and inland to Snape. It includes Orfordness, Shingle Street, Havergate Island, and the Butley, Ore and Alde Rivers. The site comprises cliffs, extensive ares of mud-flats, reedbeds, grazing marsh, saltmarsh, vegetated shingle and coastal lagoons which are of special botanical and ornithological value.


The variety of habitats on the site contributes to the overall botanical diversity of the site. Many of the habitats have a restricted distribution in the UK and support rare and specialised floral species. Of note are the saltmarsh communities that occur along the length of the rivers and the vegetated shingle (that is the second largest and best preserved area of the habitat in Britain). Species of note include several lichens, Zostera angustifolia (Narrow-leaved Eelgrass), Althaea officinalis (Marsh Mallow), Lathyrus japonicus (Sea Pea), Medicago minima (Bur Medick), Puccinellia fasciculata (Borrer`s Saltmarsh-grass), Sonchus palustris (Marsh Sow-thislte), and Vicia lutea (Yellow Vetch). The saline lagoons on the site support specialised invertebrate fauna, species of note include Nematostella vectensis (Starlet Sea Anemone) and Gammarus insensibilis.


The site is of national importance for its birdlife. Havergate Island holds the largest breeding colony of Recurvirostra avosetta (Pied Advocet) in Britain, and they also feed in large numbers of Hazelwood Marshes and the Alde mudflats. Other breeding birds on the Island and elsewhere on the site include Anas strepera (Gadwall), Anas clypeata (Shoveler), Haematopus ostralegus (Oystercatcher), Charadrius hiaticula (Ringed Plover), Sterna hirundo (Common Tern), Sterna
