EDP Baixo Sabor: Construction and Reservoir Filling Phases - Iberian Wolf [howling surveys] - [2010-2014]

Study Extent

The data were collected in a grid of 38 5x5 km squares established in the lower Sabor river valley, its tributaries, and in 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

Acoustic sampling was designed to cover the whole study area, with particular emphasis on places of confirmed or potential occurrence of Iberian Wolf. A total of 28 (2010-11), 14 (2012) or 19 (2013-14) acoustic (howling) stations were distributed throughout the 38 5x5 km squares. Surveys took place between May and November of each year. At each station, simulated howling sequences interrupted by pauses of a few minutes were performed. This method is most effective in detecting offspring, which are more likely to respond to simulated howling and so this method is just applied during the breeding season and dependence of the offspring (May to October).

Quality Control

All individual identifications were performed by qualified technicians
