This dataset is based on monthly colonial waterfowl counts in Portugal, between 20 February – 31 July of 2013 and 2014. A total of 148 wetlands sites were included in the censuses and all species of colonial waterfowl species were counted regularly. The counts were done by direct approach, except in large colonies where estimate counts were done. In non-accessible areas, the counts were based on aerial photographs, complemented by in-out movements of adult birds in those colonies. The results of each species counts are presented per river basins in a report, Encarnação V. (2014) Monitorização das espécies de aves aquáticas coloniais, with the distribution of Ardeidae (7 species), Threskiornithidae (2 species), and Phalacrocoracidae (1 species).Sampling Description
Study Extent
This report is covering a monitoring survey of colonial waterfowl species in 148 wetlands of Continental Portugal from 20 February to 31 July during 2013 and 2014.Sampling
A total of 148 wetlands were considered during the survey, distributed in 9 river basins. The abundance quantification method was carried out in the form of directed censuses, according to the characteristics of each species, except in large colonies where estimate counts were done. In non-accessible areas, the counts were based on aerial photographs, complemented by in-out movements of adult birds in those colonies.Quality Control
All initial data was inserted in a specific relational database built specifically for the project, which implemented several quality control methods. In the preparation of the dataset for the GBIF publication, data consistency was verified through cluster algorithms using OpenRefine.Method steps
- (1) Aggregation of original data from several sources (see above) into a purpose specific relational database built for the project. (2) Preparation of the dataset for GBIF publication used as source the geographic layer in shapefile format. The data layer was a vector layer containing points. The following steps were performed: - Used the WGS84 points to extract the locations from the CAOP2020; - Exported to csv and reinterpreted attributes matching to DwC standard terms.
