Coypu or Otter – Invasive Species Alert – WI MN 24/2019 UPDATE

UPDATE Mar 22: 

Earlier this week Waterways Ireland received notification of an unconfirmed report from the National Biodiversity Data Centre via National Parks and Wildlife Services of a Coypu on the Royal Canal. We are obliged to take this seriously, given the potential implications posed by a Coypu presence on Irish waterways. All evidence now leads us to believe that this was a case of mistaken identity and the report was likely that of native Otter, which are present on the Royal Canal.

As there is a legal obligation to remove such invasive species from the wild, Waterways Ireland will continue to work closely with National Parks and Wildlife Service (NPWS) and the National Biodiversity Data Centre (NBDC). The public are encouraged to contact NBDC (www.biodiversityireland.ie) with any record of the invasive Coypu, preferably with a confirmation photo, if they happen to come across this species on any waterbody
