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.

single
criteria for using this dataset:
The dataset needs to be requested from dataset creator with specific conditions of use.
other/additional criteria:
Currently the dataset still needs to be requested from the dataset creator as quality control is ongoing. All data will be made publicly available on the Freshwater Biodiversity Data Portal in the first half of 2016.
Note that 74 different persons and institutions have contributed occurrence records to the DAET dataset. Their work has to be acknowledged accordingly whenever data are used.

quality control protocols and comments:
- The underlying taxalist was checked by the freshwaterecology.info Trichoptera experts and currently holds 1708 species (including sub-species).
- Distribution data were in a first step quality controlled through GIS routines. In a second step the occurrence records were quality checked by experts, namely Hans Malicky and Wolfram Graf.
- To avoid quality issues regarding the identification of larvae, the focus of the dataset is on adult data.
- In cases of recent differentiations to sub-species older data may contain ambiguous species.
