EDP Baixo Sabor: Construction and Reservoir Filling Phases – Cliff-nesting birds, prioritary conservation species: fixed observation points [2010-2014]

Citation

Mota P, Gomes C, Zina H A, Araújo P M, Oliveira C A, Marques S M, Mendes J D, Múrias T (2020). EDP Baixo Sabor: Construction and Reservoir Filling Phases – Cliff-nesting birds, prioritary conservation species: fixed observation points [2010-2014]. Version 1.1. EDP. Sampling event dataset https://doi.org/10.15468/zikgab accessed via GBIF.org on 2025-06-19.

Description

The dataset contains records of cliff-nesting species of high conservation priority, namely birds of prey (Aves, Accipitriformes and Falconiformes) and Black Stork (Ciconia ciconia) (Aves, Ciconiiformes) collected in the lower River Sabor (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. The dataset includes results of surveys made in and around the area affected by the dam, from February 2010 to September 2014. Data consists of observations of the target species performed in fixed sampling points directed to birds of prey. Observations were made around the Sabor river, from its mouth to 42 km upstream. The presence and identity of bird species were assessed by visual and/or acoustic observation with binoculars and/or telescope. The records include taxa identified at the species level.

Purpose

This dataset is part of a broader initiative whereby the company EDP - Energias de Portugal S.A. will made available biodiversity data collected during impact assessment and biological monitoring studies.

Sampling Description

Study Extent

The data were collected within a 5-km buffer around the margins of the lower valley of river Sabor and its main tributaries, up to 42 km from the mouth, in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro e Macedo de Cavaleiros.

Sampling

The dataset includes systematic observations using binoculars and telescope made from vantage fixed points scattered throughout the study area in favourable habitats to detect the target species and other cliff-nesting bird species. A single observation session took place per site in each season (spring, summer, autumn and winter) from 2010 to 2014. A total of 16 sampling points was established in dominant features near areas with suitable habitats for cliff-nesting birds of prey. At each point, one observer spent 1 hour recording all contacts with the target species. All sessions were performed at the hottest hours of the day to maximize the probability of contacts with the target species, and they occurred only in favorable weather conditions of wind and rainfall. All identifications were made "in loco" by experienced observers, with the support of adequate field guides.

Quality Control

All individual identifications were performed by qualified technicians
