Invasive Non-native Species

New Zealand Flatworm Arthurdendyus triangulatus

The New Zealand Flatworm, Arthurdendyus triangulatus, probably arrived in the UK in the 1960s with specimen plants sent from New Zealand to a botanic garden. New Zealand Flatworms prey on earthworms, posing a potential threat to native populations. Their presence could have an impact on native species dependent on earthworms and could have a localised, deleterious effect on soil structure.

New Zealand Flatworms have been introduced into the Outer Hebrides and we have produced an advisory leaflet for local gardeners to raise awareness and stop their spread.
