Up-dated distribution maps – June 2013

Database Updates

Records were added and distribution maps up-dated for 47 species including  maps being added for the following species:

  • Japanese kelp (Undaria pinnatifida)
  • Asian sea squirt (Styela clava)

15 of the 20 records added to the National Invasive Species Database for the Asian sea squirt were digitized from published Aquatic Invasions papers with the remaining 5 records from the Marine Species Distributions in Irish Coastal Waters Database. 

The Japanese kelp record was supplied by Northern Ireland Environment Agency.

Two records were also received for raccoon (Procyon lotor) in Cork city.  The two sightings are likely to be of the one animal as the sightings were just a couple of hundred of meters apart and within 3 days of each other.

Records were also added to the Irish New Zealand flatworm Database.

Approximately 178 records were removed from Biodiversity Maps for 12 plant species.  This is due to up-dates in other databases where record review and duplicates were removed.  There are currently 27,104 records for the 102 species listed in the National Invasive Species Database  in Biodiversity Maps.
