Swedish Bird Survey: Swedish waterbird census (September)

Dataset type

This dataset that contains event based data for species which may include sampling information

Description

The Swedish waterbird census in September (Svensk sjöfågelinventering (september)) was started in 1973 as a complement to the Swedish part of the international midwinter census (Swedish waterbird census (January)). It is a valuable tool for monitoring roosting waterbirds as well as finding out which areas are important resting places for migrating waterbirds. The Swedish waterbird census (September) is one of several schemes within the Swedish Bird Survey, run by the Department of Biology at Lund University. The surveys are with a few exceptions carried out by volunteer ornithologists. In this dataset, some information is placed in the table ExtendedMeasurementOrFacts (eMoF), which is part of the Source Archive available to download directly from the dataset’s page on gbif.org. The Source Archive contains the data exactly as uploaded to gbif (verbatim). Should you choose to download the dataset as GBIF Annotated Archive instead, the data has been interpreted and quality controlled by gbif, but, the data in the eMoF will not be included, as the eMoF extension is not yet supported by gbif.
