This dataset describes the wader counts between 1975 and 1978 in Portuguese main wetlands. The report analyses the average population of each specie in each area and their fluctuation through the referred years, aiming to identify areas with major importance for these species.Sampling Description
Study Extent
This report contains annual wader counts, put together between 1975 and 1978, in of seven Portuguese wetlands: Estuário do Arade (Portimão), Estuario do Mondego (Figuera da Foz), Estuário do Sado, Estuário do Tejo, Ria de Aveiro, Ria Formosa ou Ria de Faro and Sapais de Castro Marim.Sampling
The wader counts were collected from counts reports made between 1975 and 1978. In the follow up some calculations were performed: four-year average population per area for each specie, the annual fluctuations in relation to the average, and the percentage of individuals of each species over the country total.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 GBIF publication, data consistency was verified using cluster algorithms using OpenRefine.Method steps
- Extraction of points coordinates and addiction to VerbatimdecimalLatitude e VerbatimdecimalLongitude Convert to WGS84 Calculation of coordinates precision Cross-checking with WGS84 Portuguese CAOP2020 shape to obtain location information Export to csv. with reinterpretation of attributes matching to DwC standard terms.
