EDP Foz-Tua: Riparian Birds (point counts) Ecological Monitoring Program [2011]

Study Extent

The data were collected within a 5-km buffer around the lower Tua River valley (Northeast Portugal), up to 45 km from the mouth, in the municipalities of Carrazeda de Ansiães and Vila Flor.

Sampling

Sampling was designed to cover the riparian habitats along the lower Tua River valley (river beds and riparian galleries) affected by the Foz Tua dam, including the future reservoir area. Eleven plots were established along the river, one per 2x2 km square, covering the area to be flooded. All plots were sampled once in winter 2010/11. Each sampling event was surveyed during 10 minutes, during which all birds seen or heard around the point (unlimited distance method) were recorded. Species identification and assessment of age and sex (when possible) were made in situ, with the help of appropriate field guides.

Quality Control

All identifications were performed by qualified technicians
