EDP Foz-Tua: Riparian Birds (transects) - Ecological Monitoring Program [2011-17]

Study Extent

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

Sampling

Sampling was designed to cover the main habitats for riparian and aquatic birds along the lower Tua valley affected by the Foz-Tua dam. A total of seven line transects was established in the flooded area and in control points upstream, along the river Tua. All transects were sampled once in winter (only from 2012 onward) and twice in the reproductive period (spring), in the early morning or late afternoon. Each transect was walked on foot at a constant speed of 1-2 km/h and lasted no less than 30 minutes. Species identification and assessment of age and sex (when possible) were made “in loco”, with the help of appropriate field guides.

Quality Control

All identifications were performed by qualified technicians
