EDP Foz Tua: Terrestrial Birds, Winter (point counts) - Ecological Monitoring Program [2011-2017]

Data Records

The data in this sampling event 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 349 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

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.

Geographic Coverage

The data were collected within a 5-km buffer around the valley of the River Tua (Northeast Portugal), up to 45 km from the mouth, in the municipalities of Alijó, Carrazeda de Ansiães, Murça, Vila Flor and Mirandela.

Taxonomic Coverage

The taxonomic coverage of this dataset spans 1 phylum, 1 class, 12 orders, 32 families, 56 genus and 70 species.

Temporal Coverage

Project Data

The dataset contains records of terrestrial birds (Aves) collected in plots along the lower Tua River valley and included in the Ecological Monitoring Program of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected in January and February of 2011-2017, during field visits to 28 (2011), 27 (2012) or 60 (>2013) sampling plots with favorable habitats for terrestrial birds in 26 2x2 km squares within a 5-km buffer around the lower Tua River valley. The occurrence of the target taxa was documented through 349 observation events. In total, 5899 observations were identified to the species rank. The most abundant species were Fringilla coelebs (939 occurrences), Erithacus rubecula (574), Sylvia atricapilla (467), Parus major (334). Turdus philomelos (333) and Sylvia melanocephala (312).

Sampling Methods

Sampling was designed to cover the main habitats for terrestrial birds along the lower Tua valley affected by the Foz-Tua dam, including the future reservoir area. In the first two years (2011 and 2012), a total of 28 point counts distributed along the valley was used, some of which were duplicated as they included more than one habitat type. A final grid of 60 sampling points was established in 2013 and used afterwards. All plots were sampled once or, in some cases, twice per winter. in the early morning or late afternoon. Each sampling event had 5 minutes, of duration in which all birds seen or heard in two bands of 50m around the point were recorded. Species identification and assessment of age and sex (when possible) were made “in loco”, with the help of appropriate field guides.
