Established in 2006, Chowder Ness is a coastal realignment scheme created by ABP as part of a pioneering agreement with English Nature, the RSPB, the Environment Agency and the Yorkshire and Lincolnshire Wildlife Trusts.
This large area of flooded land has created a mudflat environment that is perfect for waders, shorebirds and waterbirds and already completely compensates for the proposed Green Port Hull development.
Enviromental compensation for the site has already been achieved through the creation of new areas of intertidal habitat.
Intertidal habitats such as mudflats and saltmarshes have been developed along sheltered coastal areas that the flood and ebb tides cover and uncover on a twice-daily basis. Such coastal habitats are of considerable importance to birds and other wildlife, as they provide feeding, roosting and breeding areas for birds and support a wide range of fish and invertebrate species.
Both Shorebirds and more than 16 different waterbird species including Shelduck, Golden Plover, Lapwing, Dunlin, Curlew, Black-Headed Gull and Common Gull are found at Chowder Ness. The Humber Estuary is an important overwintering area for these species with least 1.7 and 1.4% of their British wintering population visiting the estuary every year
Alongside the bird population, invertebrates, that are an important source of food for shorebirds, have colonised the new sediment with between 571 and 15,429 specimens, belonging to between two and six species, found per m². The abundance, diversity and biomass of species is increasing and is now on average greater than that found in the fronting mudflats.
In 2009 a small proportion of the site was developed into saltmarsh. This saltmarsh is mostly dominated by sea aster and supports a range of farmland bird species including moorhen, skylark, meadow pipit, pied wagtail, reed bunting and grasshopper warbler.
