The VI national White Stork (Ciconia ciconia) census in Portugal (2014)

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 5,132 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 project “VI Censo Nacional de cegonha-branca (Ciconia ciconia) - 2014” aimed to register the breeding population of the White Stork throughout Portugal Mainland. The records are related to the presence of Ciconia ciconia (Linnaeus, 1758).

Sampling Methods

The data was obtained for the elaboration of the VI national White Stork census in Portugal, with the survey of the presence of nests of Ciconia ciconia on Mainland Portugal. In 2014, during the breeding season from March to July, all municipalities with some references to White Stork nesting or with a favorable habitat for the species were visited. For each detected nest, the following informations was recorded: - Detailed description of the location; - The structure supporting the nest (pole, tree, rocks, human constructions, others); - Determination of nest occupation, with two possibilities: occupied: with an individual/couple or recent built nest or evidence of recent presence of birds (dejects) or nesting evidence during the nesting season; empty: nests without situations described above.

Method step description:

1. The 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: - Conversion of the spatial layer to geographic coordinates using WGS84 as reference system; - Used the points to determine the locations based on the Carta Administrativa Oficial de Portugal 2020 (CAOP2020) and OpenStreetMaps; - Exported to csv and reinterpreted attributes matching to DwC standard terms.
2. The dataset presents detailed information of the structures supporting the nest, indicating the existence or absence of artificial platform (AP). The dataset also presents several notes of the registers on occurrenceRemarks originally as "Observações". The original colum "Data" was considered the DwC field "verbatimEventDate". When it was empty, the DwC field "eventDate" was filled in as "2014-03/07" considering the study period described in the report of the VI national White Stork census, between March and July 2014. There is also records carried out on September 30, 2014.
3. In "dynamicProperties": - "NORDEM" = sequential order number to the occurrence. The numbers are not unique. So, it was not considered an identifier of the occurrence; - "DICO" = other number for the occurrences. The numbers were generally unique, with an exception; - "dico_nord" = the joining of the two previous terms; - "SUPORTE_FI" = original notes of the structures supporting the nest; - "N_NINHOS" = number of occupied nests; - "N_NINHOSV" = number of empty nests (or without situations described in the occupied nests); - "OUTRA_ESPE" = other species presents at the time of the record; - "N_NINHOS_CO" = number of nests of the species co-occurring with Ciconia ciconia
