Important Invertebrate Areas About IIAs Selecting and Mapping IIAs Supporting Invertebrate Conservation IIAs in Planning IIA Landscapes Single Species IIAs Using IIA Maps and Profiles FAQ IIA Data Providers IIA Document Library IIA Shapefiles

Important Invertebrate Areas (IIAs) are the best places in Great Britain for our invertebrates, which have been identified using the most up-to-date data available from over 80 national expert recording schemes. They support some of our rarest and most threatened species, vulnerable habitats and unique assemblages of invertebrates.

The IIA project would not be possible without the expert knowledge, dedication and guidance of the recording community

The following organisations have either provided data to help inform the broad-scale IIA map or helped to design the methodology as part of the project expert group:
