The National Biodiversity Data Centre is delighted to announce the four sites that will be competing in this year's Ireland's BioBlitz which will take place on 23 & 24 May. The sites are all extremely interesting heritage sites that provide a variety of habitats and interesting biodiversity. This should make for very competitive recording this year.

The four sites are Howth Head, Co. Dublin, Glenarm Estate, Co. Antrim, Cong / Clonbur Woodlands on the Galway / Mayo border and Derrynane Historic Property, Co. Kerry. The Data Centre is very grateful to Fingal County Council, National Museums of Northern Ireland, Coillte and the Office of Public Works who are our partners in this years event. Please see the BioBlitz website .
