Islanders asked to look out for invasive flatworms in Guernsey
A record number of invasive species of flatworms have been sighted in Guernsey.
Three non-native forms of the species, which feed on earthworms and snails have been identified on the island.
The Guernsey Biological Records Centre (GBRC) is now asking islanders to keep an eye out for the following species and report any possible sightings:
The Obama flatworm (Obama nungara) which is native to South America
Australian Flatworm (Australopana sanguinea)
Black Kontikia Flatworm (Kontikia ventrolineata) which is native to Australia and New Zealand.
The most damaging species - the New Zealand Flatworm - has not yet been spotted on the island. However, the GBRC says the public should keep a look-out.
It is described as being flat with dark purple-brown markings, at a size of around 5-15 cm long with points at both ends. They are also covered in a sticky mucus which can cause irritation if it makes contact with skin. Their eggs are like flat, hard blackcurrants.
The GBRC have also issued this advice to help keep flatworms out of gardens on the island.
Avoid introducing new plants into your garden in pots with soil. Where possible, grow plants from roots or buy bare rooted plants.
Ensure any new top soil has been sterilised and stored correctly.
Dispose of soil or plants carefully - do not dump them in the environment, especially on nature reserves.
