EDP Foz-Tua: Large Mammals (diurnal transects): Ecological Monitoring Program [2011-2017]

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 434 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 35 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, 7 orders, 11 families, 15 genera and 14 species.

Temporal Coverage

Project Data

The dataset contains records of large mammals (Mammalia) collected in transects along the lower Tua River, 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 August 2017, with 47 (2011), 24 (2012-2014) and 28 (>2014) line transects in areas with favorable habitats for large mammals within a 5-km buffer around the River Tua lower valley. The occurrence of the target taxa was documented through 1460 positive records. In total, 177 were identified only to class, 7 to order, 27 to family and 50 to genus, while 1229 were identified to the species rank. The most abundant species (> 100 records) were Vulpes vulpes (565), Sus scrofa (214) and Genetta genneta (164).

Sampling Methods

Sampling was designed to cover the main habitat types for large mammals in and around the lower Tua valley affected by the Foz-Tua dam (including the reservoir area). Up to 47 transects were established in 24 2x2 km squares in the flooded area and in control areas upstream. Each transect, with a length of of about 500 m, was walked on foot, during daytime, by two observers, one each side of the transect, which recorded all individuals and/or signs of presence of the target species (e.g. scats, footprints, tracks, trails, rooting, hog wallows, rubs). All recorded contacts/signs have been identified or collected for later identification.
