About the reserve

This small island, or ‘ait’, is one of the Trust's more unusual reserves - and benefits from its isolation from people. It is remarkable for its tall canopy of mixed woodland, rooted on a bank of ground that is regularly inundated by high tides, and supports one of the only remaining areas of natural tidal marginal habitat still not developed or canalised on the Thames.

The Ait also provides an undisturbed sanctuary for a variety of birds, and supports several rare mollusc populations.  

History of Isleworth Ait

Isleworth Ait was historically part of the Syon Park Estate, owned by the Duke of Northumberland, and was once a centre for the production of osier, a type of willow used to weave baskets. Five neighbouring islands have now disappeared. Today Thames Water owns the Ait, after the Metropolitan Water Board bought the island from the Duke of Northumberland in the 1930s. It has been managed by London Wildlife Trust as a nature reserve since 1995.
