The dataset contains records of the Otter (Lutra lutra) collected in the lower valley of the River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (EMP) and the Compensatory Measures Monitoring Program (CMMP) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of surveys carried out inside and around the area affected by the dam, from April 2015 to July 2020. Sampling was performed in transects distributed along the lower Sabor river valley (including some tributaries), and along the rivers Maçãs and Angueira, up to 73 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.Purpose
This dataset is part of a broader initiative and commitment assumed by the company EDP - Energias de Portugal S.A., which permits to make available biodiversity data collected from infrastructural impact assessments and biological monitoring studies in the scope of hydroelectric dams’ construction and exploitation.
Sampling Description
Study Extent
The data were collected in 50 transects in the lower Sabor river valley, its tributaries and the rivers Maçãs and Angueira, from the river mouth up to 73 km upstream, in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro, Macedo de Cavaleiros, Vimioso and Bragança.Sampling
Sampling was designed to cover the whole valley of the lower Sabor river, its tributaries, and the rivers Maçãs and Angueira. A total of 50 transects was established in the study area. The transects had a minimum lenght of 200 m and, within this distance, the survey was stopped after the detection of the first confirmed sign of presence of the species (e.g., spraints, footprints). If there were no evidences of presence in the first 200 m, the transect was extended to a maximum of 600 m, after which, if the absence of signs persisted, the species was considered absent in the transect. Each transect was performed on foot, during daytime, by one or two observers, and the riverbed and its margins were carefully searched for signs of otter's presence (scats, footprints). All scats found were identified in the field and then taken to the laboratory for dietary analysis. The survey was based on indirect signs of otter presence, because individuals of the species are difficult to observe directly, and because the presence signs (spraints and footprints) can be unequivocally identified by experienced technicians. The database only includes the initial points of the transects along a particular water line, independently of the direction of the transect.Quality Control
All identifications were performed by qualified techniciansMethod steps
