The Distribution Atlas of European Trichoptera (DAET) database is a collection of about 561.000 occurrence data of caddisflies containing 413.000 datasets of adult Trichoptera from all over Europe (and a few records from Asia and Africa). The data compilation process was initiated by the EU funded BioFresh project (www.freshwaterbiodiversity.eu) through its contingency fund. With the end of BioFresh 2014 work on the database continued, mostly focusing on filling the distribution gaps and an extensive quality control. Occurrence data in the dataset were provided by 74 data holders based on records from more than 400 different caddisfly collectors. Additional data (about 15.000) were gained through literature evaluation. All data will be made available through the Freshwater Biodiversity Data Portal (www.freshwaterplatform.eu) in the first half of 2016.

More information on this dataset can be found in the Freshwater Metadatabase - BF_CF9 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BF_CF9).
