EDP Baixo Sabor: Birds of Riparian Habitats - Reservoir Filling [2015] and Exploration [2015-2020] Phases

Study Extent

The study was conducted in part of the sub-basin of river Sabor affected by the Baixo Sabor Hydroelectric Dam. The sampling was centered in the area affected by the reservoir filling of Feiticeiro and Baixo Sabor dams, as well as in some affluent streams, in a 1-km buffer centered in the Sabor river, up to 53 km upstream the river mouth, in the municipalities of Torre de Moncorvo, Mogadouro, Alfândega da Fé and Macedo de Cavaleiros.

Sampling

Sampling was designed to cover all the Sabor river stretches affected by the reservoirs filling of Feiticeiro and Baixo Sabor dams (PME), as well as selected ponds and weirs recovered or constructed in a buffer of a 1-km around the river (PMC). A total of 69 sampling points was used. At each point, a 10-minute sampling session was performed with binoculars and a telescope, in which all birds detected by sight or sound were recorded. Although an “unlimited distance” method was used, an estimate of the distance to the observer (class of distance) was recorded. Species identification, age and sex determination (when possible) were performed by direct observation and confirmed with appropriate field guides when necessary.

Quality Control

All individual identifications were performed by qualified technicians

Data were collected in a 1-km buffer around the Feiticeiro and Baixo Sabor dams, from the river mouth up to 53 km upstream, and in selected places of some of the affluent streams, in the municipalities of Torre de Moncorvo, Mogadouro, Alfândega da Fé and Macedo de Cavaleiros.
