Invasive species week: Floating pennywort a spreading menace

Invasive species week runs till 29 March and is encouraging river users to think about non-native species and aquatic plants such as floating pennywort.

Ministers launch invasive species week in Dublin at the British Irish Council on Friday 23 March

Minister Geoffrey Boot MHK Isle of Man, Hannah Blythyn AM Wales, Minister Denis Naughten TD Ireland, Lord Gardiner, UK Biosecurity Minister and Deputy Steve Luce, Jersey.

Reports of floating pennywort in our rivers and lakes have reached a record high with 50 tonnes of the invasive plant being removed from the River Thames by the Environment Agency in 2017.

Fast-growing plants like floating pennywort can spread into the wild if they are not properly disposed of when removed from garden ponds ponds. The Be Plant Wise campaign has handy tips for gardeners on how to prevent this from happening.

Lord Gardiner, the Biosecurity Minister, will see the effects of floating pennywort on Little Britain lake, Hillingdon, and hear about the work being carried out to prevent this plant from spreading further in the River Colne on Monday, 26 March 2018.

He will also see new signs being put up to encourage fishermen and boaters to Check, Clean, Dry their equipment and clothing to avoid spreading invasive species.

Biosecurity Minister, Lord Gardiner said:

Invasive species pose a real threat to our country’s native plants and animals and cost the economy at least £1.8 billion a year.

The Check, Clean, Dry campaign is playing a key role in raising awareness of these threats – helping to prevent new arrivals and stopping the spread of invasive species already here. It is great to see the whole community of river users supporting this programme to protect the future of our precious native species.

As well as following the Check, Clean, Dry advice, people can help by reporting sightings of invasive plants through the PlantTracker app.

Lord Gardiner’s visit comes as part of a wider push by government to promote Invasive Species Week. The week is an annual awareness-raising campaign organised by the GB Non-Native Species Secretariat (NNSS) and Defra to get members of the public thinking about simple steps they can take to stop the spread of invasive species which threaten Britain’s plants and animals.
