Latest version published by EDP - Energias de Portugal on Feb 18, 2020 EDP - Energias de Portugal

The dataset contains records of reptiles (Reptilia) collected in the lower valley of the River Tua, and included in the Ecological Monitoring Program (2011-2017) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2011 and August 2017 during field visits to 24 (2011-2014) or 28 (2014-2017) sampling transects with favorable habitats, in 24 2x2 km UTM squares in the area of the lower Tua valley directly or indirectly affected by the Foz Tua dam. The presence of individuals was recorded by direct observation.

Project Data

The dataset contains records of reptiles (Reptilia) collected in transects along the lower Tua River valley, and included in the Ecological monitoring Program (2011-2017) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2011 and August 2017, during field visits carried out in 28 sampling transects with favorable habitats for reptiles, within a 5-km buffer around the River Tua lower valley. The occurrence of the target taxa was documented through 405 observation events in 79 sampling points. In total, five taxa were identified to the species level. The most abundant species (>15 individuals) were Podarcis hispanicus (52 individuals observed), Tarentola mauritanica (20) and Psammodromus algirus (17)

Title EDP Foz Tua Reptiles - Ecological Monitoring Program [2011-2017]
Identifier EDP Biodiversity Data
Funding The work was funded by EDP - Energias de Portugal, S.A.
Study Area Description The study was conducted in part of the sub-basins of river Tua, prior to (2011) and during the construction (2011-2015) and subsequent flooding (2016-2017) of the lower part of this river valley by the Foz Tua Hydroelectric Dam. The sampling was centered in suitable habitats for reptiles found in a 5-km radius buffer around the future reservoir banks and up to 50 km from the Tua mouth.
Design Description The objective of the study was to monitor changes in the distribution patterns and abundances of species of Reptiles in the area of the Foz Tua Hydroelectric Dam, prior to (2011) and during (2011-2016) the dam construction, and in the subsequent flooding of the river valley (2016-2017).

Sampling Methods

Sampling was designed to cover potential areas of nocturnal occurrence of amphibians (roads, tracks) in a grid of 2x2 km squares in, and around, the lower Tua valley affected by the Foz-Tua dam, including the reservoir area. A representative sample of transects of variable length was set up (one transect per square), covering the area affected by the dam and a control area upstream. Each transect was visited once in spring (April-Jun) and in summer (July-August), of 2012 to 2016. The transects were performed by two observers simultaneously (one on each side of the transect), during which all evidence (e.g., skin shedding) and individuals observed in displacement or located in potential refuge sites (e.g., stones or logs) along the transect, were identified and recorded. Species identifications were made with appropriate field guides. Sampling was carried out on days with favorable weather conditions to reptilian activity, especially on sunny or cloudy days. On days with very high temperatures (above 30 ° C) monitoring was preferably conducted at warmer times of day, particularly during the first four hours after dawn and the last three hours before dusk.

Study Extent The data were collected within a 5-km buffer around the Tua lower valley (Northeast Portugal) located in the region of Trás-os-Montes e Alto Douro, up to 50 km from the mouth, in the municipalities of Carrazeda de Ansiães, Vila Flor, Alijó and Mirandela.
Quality Control All identifications were performed by qualified technicians.
