Description
This dataset is based on the Atlas of Amphibians and Reptiles of Portugal published by ICNF in 2008. The publication of this document is related to the implementation of the National Strategy for the Conservation of Nature and Biodiversity, whose 5th strategic option concerns development throughout the national territory of specific actions for the conservation of species and habitats, defining as one of the action directives the elaboration of several distribution atlases. The Atlas shows, according to the record of observations made up to the date of its publication, the distribution, in Portugal, of amphibians and reptiles that are autochthonous in the Portuguese territory, and also exotic species existing in the wild: 17 species of amphibians; 30 species of terrestrial reptiles; and 5 species of sea turtles. The original publication presents, for each of the species, a sheet with the characterization of the species and notes on the main threats and measures for its conservation.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 82,170 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data
The publication of this document is related to the implementation of the National Strategy for the Conservation of Nature and Biodiversity, whose 5th strategic option relates to the development throughout the national territory of specific actions for the conservation of species and habitats, defining as one of the directives of action the elaboration of several distribution atlases. This Atlas results from a protocol established by the then ICNB with the CBA - Center for Environmental Biology of the Faculty of Sciences of the University of Lisbon and with CIBIO - Center for Research in Biodiversity and Genetic Resources of the Univ. from Porto.

| Funding | This work was co-fund by ICNF, I.P. and the European Union, through the Environment Operational Programme (application 1.1/00021– Documentos Estruturantes da Conservação da Natureza e da Biodiversidade). The preparation of this resource for publication through GBIF was supported by Project PORBIOTA—Portuguese E-Infrastructure for Information and Research on Biodiversity (POCI-01-0145-FEDER-022127), under the Operational Thematic Program for Competitiveness and Internationalization (POCI), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (FEDER) and FCT. |

Sampling Methods
Data collection was based on previous atlas for the region, scientific publications, unpublished field data by the atlas authors and newly collected field data for the atlas project. In the case of newly collected data, coordinates and date are automatically collected from GPS records. All data was inserted in a specific database build for the project.
| Study Extent | The geographic area considered for the original study was Portugal Mainland. The species included are native species of amphibians and reptiles for the country, and exotic species existing in the wild. |
|---|---|
| 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 step description:
- Aggregation of original data from several sources (see above) into a purpose specific relational database built for the project. For details, see Loureiro et al (2008)
- Preparation of the dataset for GBIF publication used as source the geographic layer in shape file format. Although the data layer was a polygon layer with a 10 km grid, the attribute table contained, for the field records, original GPS coordinates with higher precision. In that case, the coordinates with higher spatial precision were considered. The following steps were performed: - conversion of the spatial layer to geographic coordinates using WGS84 as reference system; - determine centroids of grid polygons. If the record contains coordinates in the database with higher precision, these were kept; - determine WKT for the polygons for which centroids were considered; - export to csv and reinterpret attributes matching to DwC standard terms.
