The dataset contains records of the Roe Deer (Capreolus capreolus), a major wild prey of the Iberian Wolf, collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of surveys made in and around the area affected by the dam, from June 2010 to April 2014. Sampling was performed in transects distributed along the lower Sabor river valley (and some tributaries), and in rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence of the target species was assessed through faecal pellet surveys, due to difficulties in directly observing the species.

The dataset contains records of the Otter (Lutra lutra) collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of surveys made in and around the area affected by the dams, from September 2010 to November 2013. Sampling was performed with camera-traps distributed along the lower Sabor river valley (and some tributaries) and along the rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species were assessed with the visualization of photos taken through camera-trapping.

This dataset includes results of surveys made in and around the area affected by the dam, from November 2010 to December 2014. Sampling was performed in transects distributed along the lower Sabor river valley (and some tributaries), and along the rivers Maçãs and Angueira, up to 42 km upstream. The presence and identity of the target species were assessed through the presence of faeces (spraints) and/or footprints of the target species.

The dataset contains records of Iberian Wolf (Canis lupus) collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of spotlight counts made in and around the area affected by the dam, from June 2010 to September 2014. Sampling was performed at fixed transects (spotlight counts) distributed along the lower Sabor river valley and some of its small tributaries, and in the rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species would be assessed by direct observation of individuals during spotlight counts. No detection of Iberian wolf was obtained during these surveys, thus the dataset reports on locations where the species was deemed absent, thereby providing a baseline to assess future changes in species occurrence patterns.

The dataset contains records of a key prey species of Bonelli’s Eagle (Aquila fasciata) and other large birds of prey, the Rabbit (Oryctolagus cuniculus) (Mammalia, Lagomorpha), collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of line transects performed each season (winter, spring, summer and autumn), in the known territories of the Bonelli's Eagle in the lower Sabor river valley, from February 2010 to September 2014. Data consists of presence signs (scats, latrines) recorded per transect surveyed.

The dataset contains records of the Wild Boar (Sus scrofa), a main natural prey of the Iberian Wolf collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of surveys made in and around the area affected by the dam, from June 2010 to September 2014. Sampling was performed in transects distributed in the area of the lower Sabor river valley (and some tributaries) and in rivers Maçãs and Angueira, from the river mouth up to 42 km upstream. The presence and identity of the target species were assessed through presence signs, mainly scats. ontains records of the Wild Boar (Sus scrofa), a main natural prey of the Iberian Wolf collected in the lower valley of River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A.
