(asked on 29th April 2024) - View Source

Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government whether they are monitoring the spread of non-native flatworms in the UK, particularly the New Zealand flatworm; what assessment they have made of any recent increases in the numbers of non-native flatworms in the UK; and what steps they are taking (1) to combat the spread of non-native flatworms, and (2) to advise the public.

No recent assessment has been made of the numbers of non-native flatworms in the UK. While some data on New Zealand flatworms (Arthurdendyus triangulates) is collected this is not sufficiently systematic to support a full assessment.

We encourage the public to submit sightings with photographs to iRecord (which can be found at irecord.org.uk) such that the species can be accurately identified. The record is then uploaded to the biological records centre and will improve our understanding of the distribution of the species.

We have developed a Horticulture Pathway Action Plan (PAP) (copy attached) which aims to prevent and manage the risk posed by species such as the New Zealand flatworm using measures such as raising public awareness, minimizing the contamination of goods, commodities, vehicles and equipment by invasive non-native species, and ensuring appropriate border checks. An action within this document specific to flatworms is to establish a task-and-finish group to review existing guidance and develop new guidance on flatworms. We are due to consult on the PAPs later this year, and following the conclusion of that exercise, the actions such as this one in the PAPs will commence.

In addition, Invasive Species Week is coming up and will take place from the 20th to 26th May 2024. This is an annual week of awareness raising and events to help prevent the spread, and reduce the harmful impacts, of invasive non-native plants and animals.
