Note: InvertebrateIreland aims to put online all checklists of Irish invertebrates compiled by acknowledged experts.
Terrestrial and Freshwater Non-insect invertebrates
In 2010, as part of the initiative to review the State of Knowledge on Ireland’s Biological Diversity the National Biodiversity Data Centre produced an inventory of sources of biodiversity data. The inventory was developed by inviting recognised national experts to identify the state of knowledge.
