On The Land
Below are brief descriptions of several species to look out for on land around the estuary. Further detailed information sheets can be viewed by following the links.
American Mink (Mustela vison) - Originally Introduced in the 1920s, for fur farming, it has become established throughout the UK, as a result of escapes and deliberate introductions. It has had (and continues to) a significant impact on native wildlife, especially water voles, sea birds and fish on which it predates.

Asian Hornet (Vespa velutina) - Not currently present in the UK, but is rapidly spreading throughout France. It is highly possible that it will reach our shores, through imported plants, flowers, fruit, untreated timber and freight containers. Highly aggressive, its arrival would pose a significant threat to honey bees and other pollinators. Its nests are usually found high up in trees. Species Alert! Report any sightings as soon as possible to: alert_nonnative@ceh.ac.uk

Giant Hogweed (Heracleum mantegazzianum) - First recorded in the early nineteenth century, it is easy to identify when fully grown, owing to its enormous size. Usually found on river banks, wasteland and rough pasture, contact with the plant must be avoided, as even minute amounts of sap can cause blistering. It is an offence under schedule 9 of the Wildlife & Countryside Act to plany or otherwise cause this species to grow in the wild. Please report any sightings (along with a photograph), using our on-line form.
