Movhera Foz Tua: Exploration Phase - Cliff-nesting species (Aquila fasciata): Breeding sites [2021-2023]

Citation

Description

The dataset contains records of Bonelli’s Eagle (Aquila fasciata, Aves) nests and observations of other cliff-nesting species of high conservation priority, collected in the lower valley of River Tua (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Foz-Tua Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A., subsequently (2021) transferred to Movhera – Hidroelétricas do norte, S.A. This dataset includes results of nest surveys carried out at and around the area affected by the dam, from January 2021 to May 2023. Data consists of observations of all nests of the target species found in the two territories recorded in the study area, which were followed throughout the reproduction period (January-July) of each year. The records include the number of young produced by each couple in each year, if available. The target species was the Bonelli's Eagle (Aquila fasciata), but records were also kept of individuals of Griffon (Gyps fulvus), Egyptian Vulture (Neophron percnopterus) and Peregrine falcon (Falco peregrinus). Due to the vulnerability of these species and their nest site locations, the precision of the geographic coordinates was degraded to 0.01, according to the recommendations of Chapman & Grafton (2008). The original (undegraded) coordinates dataset may be provided upon request by the resource contact from Movhera, who will define the terms and conditions for its use.

Purpose

This dataset is part of a broader initiative and commitment assumed by the company Movhera – Hidroelétricas do Norte S.A., which permits to make available biodiversity data collected from infrastructural impact assessments and biological monitoring studies in the scope of hydroelectric dams’ construction and exploitation.
