EDP Baixo Sabor: Construction and Reservoir Filling Phases - Otter: camera-trapping - [2010-2013]

Study Extent

The data were collected in 49 5x5 km squares in the lower Sabor river valley, some of its tributaries, and along the rivers Maçãs and Angueira, from the river mouth up to 42 km upstream, in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro and Macedo de Cavaleiros.

Sampling

Sampling was designed to cover the whole valley of the lower Sabor river, some of its tributaries, and the rivers Maçãs and Angueira. A maximum of 15 (in 2010) or 20 (in 2011-13) automatic cameras was deployed in the study area (one or two per 5x5 km square). In 2010 (an experimental period), the cameras were deployed for a maximum period of 15 days. Starting in 2011, a maximum exposure period of three months was adopted, with the cameras being inspected at the end of each month. From 2012 onward, an increasing number of cameras were lost, due to theft, damage or destruction, forcing their substitution. The dataset presents the total number of photos taken for the target species for each exposure period, by the combined set of cameras in each square.

Quality Control

All individual identifications were performed by qualified technicians
