EDP Foz-Tua: Reptiles (point counts): Complementary Studies [2010]

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, Murça and Mirandela.

Sampling

Sampling was designed to cover the main habitat types for reptiles in and around the lower Tua River valley affected by the Foz Tua dam construction (including the reservoir area). Each sampling plot was visited once in the winter (February-March) of 2010. All habitats were searched for reptilians (adults or juveniles), and all individuals detected were recorded. Species identification and assessment of age and sex (when possible) were made in situ, with the help of appropriate field guides.

Quality Control

All identifications were performed by qualified technicians.
