The Solent Forum

Working in parnership for the future


Each winter Britain sees the arrival of millions of waterbirds of many different species from the Arctic and northern Europe. The Solent is one of the prime destinations for these birds.  The marshes, beaches and creeks around the Solent are important feeding and nesting sites for many wading and waterbirds. The waders and wildfowl for which the Solent is internationally important are: Bar-tailed Godwit, Black-tailed Godwit, Dark-bellied Brent Goose, Dunlin, Grey Plover, Little Egret, Redshank, Ringed Plover and Teal.

The RSPB reserve at Langstone occupies one third of Langstone Harbour - a muddy estuary that attracts large numbers of birds all year round. Terns, gulls and wading birds descend to breed on the islands in spring and summer, while thousands of waders and brent geese migrate from the Arctic to feed and roost in safety here.  The reserve occupies one third of the Langstone Harbour tidal estuary and consists mostly of intertidal mud but includes five small islands composed of saltmarsh and shingle ridges. Apart from a landing area for recreational boat users on one of the islands, access to the reserve is restricted, thereby allowing birds to breed, feed and roost in an undisturbed state and the fragile habitats, with their specialised fauna, to develop naturally. The invertebrates and vegetation of the mudflats are a rich food source for wildfowl and waders, while the islands are used for breeding by gulls, terns and waders and as a roosting site during high-tide periods.

In the last five years, Langstone Harbour supported an average of 37,593 birds, while North West Solent supported 14,922, Portsmouth Harbour supported 14,324 and Southampton Water supported 13,039 (source, RSPB).  The biggest UK colony of Mediterranean Gulls also nest in Langstone Harbour during the summer among the giant colonies of Black-headed Gulls and important numbers of their slimmer cousins, the fork-tailed Common, Little and Sandwich Terns.

There are approximately 67 ha of seagrass beds in Portsmouth Harbour, which are found mainly in the north-west of the harbour. These beds include both Zostera marina (found on the low shore) and Zostera noltii (on the upper to mid shore). The seagrass beds are amongst the most extensive in Britain and are an important food source for dark-bellied brent goose. The saltmarsh areas are mainly comprised of cordgrass (Spartina) swards and provide feeding and roosting areas for overwintering birds.

On the Isle of Wight, the RSPB’s Brading Marshes Reserve covers most of the beautiful valley of the lower River Yar running from the village of Brading to the sea at Bembridge Harbour. The extensive series of footpaths around the site provide the chance to see a wide range of birds including buzzards, little egrets and green woodpeckers. In 2012, Natural Enterprise was commissioned by the Isle of Wight Council to bring together, into one database, the available published survey information on the numbers and locations of selected winter birds feeding at low tide on Ryde Sands SSSI. The purpose of this work is to aid the identification and delivery of mitigation requirements for the European and equivalent Ramsar site within the Ryde Area Action Plan. A second report provided an Assessment of the Recreational Impacts on the European Sites of the River Medina and Ryde Sands with Recommendations for Mitigation.

All this richness combines to make the Solent one of the most important places for wetland birds in Europe, protected under international law, and a delight for visitors.  For more information please visit the websites of the RSPB, Wetland Bird Survey and the Hampshire Ornithological Society.

Bird Aware Solent

Bird Aware Solent raises awareness of internationally protected birds that spend the winter on the Solent.

Every winter 125,000 ducks, geese and wading birds fly to the Solent from places as far away as Iceland and Siberia. To survive the winter, birds such as turnstone and sanderling need to feed, rest and build up enough energy to be strong enough to fly back to their breeding grounds each summer. Their survival relies on preventing bird disturbance and the Bird Aware team help people understand the impact of this by engaging with visitors and communities along the Solent.

Everyone can help by looking out for birds and keeping your distance from them, by staying on paths and by making sure dogs are always in sight.

Solent Recreation Mitigation Strategy (SRMS)

Under the strategy housing developers are required to make financial contributions to mitigate the impacts from increased recreational use of the coast.

The developer contributions are used to fund Bird Aware Solent which provides:

The strategy came into effect on 1 April 2018.
