EDP Foz-Tua: Riparian Birds (transects) - Ecological Monitoring Program [2011-17]

Description

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 117 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, 16 orders, 41 families, 67 genus and 76 species.

Temporal Coverage

Project Data

The dataset contains records of riparian birds (Aves) collected in transects 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 between June 2011 and June 2017 during field visits to five (2011-2011-2014) or seven (>2014) sampling transects with favorable habitats for riparian birds along 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 riparian and aquatic birds along the lower Tua valley affected by the Foz-Tua dam. A total of seven line transects was established in the flooded area and in control points upstream, along the river Tua. All transects were sampled once in winter (only from 2012 onward) and twice in the reproductive period (spring), in the early morning or late afternoon. Each transect was walked on foot at a constant speed of 1-2 km/h and lasted no less than 30 minutes. Species identification and assessment of age and sex (when possible) were made “in loco”, with the help of appropriate field guides.
