Climate exposure
This is about exposure to a nationwide pressure this habitat type carries — not a verdict on this site's own management.
Coastal habitats are exposed to sea-level rise and storm erosion. Where hard sea defences sit behind them, there's nowhere landward to retreat to — a squeeze that keeps compressing the habitat no matter how well it's managed.

Description
Area, 62.2 ha. 153.6 ac. Description The Adur Estuary, together with Rye Harbour further to the east, represent the only significant areas of saltmarsh between Chichester and Pagham Harbours in West Sussex and Sandwich Bay in Kent, The estuarine plant communities are unusual due to the relative scarcity of cord grass, Spartina spp. The large area of intertidal mud flats within the estuary are important for a variety of wading birds. Saltmarsh plants fringe most of the estuary and in places have colonised large areas of mud flats. Sea purslane Halimione portaculoides dominates most of the areas above mean high water mark and annual seablite Suaeda maritima is also extremely frequent in these areas. Towards the mean low water mark, glasswort Salicornia sp. is dominant and sea aster Aster tripolium becomes more abundant. Other species are scattered throughout the saltmarsh community, including common sea lavender Limonium vulgare, thrift Armeria maritima, sea plantain Plantago maritima and sea poa grass, Puccinellia maritima. Cordgrass Spartina spp. is noticeably absent from most of the estuary, but a small stand does grow southeast of the Old Shoreham Bridge. At the landward margin of the saltmarsh a variety of herbs and shrubs are frequent, including mugwort Artemisia vulgaris, orache Atriplex spp., teasel Dipsacus fullonum, yarrow Achillea millefolium and elm Ulmus procera. The intertidal mud flats of the Adur Estuary support a number of wading birds, particularly redshank, dunlin and ringed plover. The number of ringed plover regularly exceed one percent of the total British population, making the estuary of national importance for this species. A variety of species breed within the reedbed adjacent to the estuary north of the A27, including moorhen, reed warbler and sedge warbler. The estuary embankment near the car park supports a large colony of viviparous lizards, Lacerta agilis.

Insects to look out for
These moths, butterflies and beetles are known to feed on plants recorded at this site, and carry a notable UK conservation status — but a host-plant being present doesn't mean the insect has actually been recorded here. Treat this as "worth watching for," not a confirmed sighting.
