Movhera - Hidroelétricas do Norte, S.A.. Sampling event dataset https://doi.org/10.15468/7xhzj4 accessed via GBIF.org on 2024-12-15.Description
The dataset contains records of nocturnal birds (Aves: Strigidae), and particularly the Eagle Owl (Bubo bubo) collected in the lower valley of the River Tua and included in the Ecological Monitoring Program (2021-2023) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A., subsequently (2021) transferred to Movhera – Hidroelétricas do Norte, S.A. Data were collected between February 2021 and June 2023 during field visits to 11 sampling points on the area of the lower Tua valley directly affected by the Foz-Tua dam. The presence of individuals was recorded by acoustic observation.Purpose
This dataset is part of a broader initiative whereby the company Movhera – hidroelétricas do Norte S.A. will make 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 Tua lower valley (Northeast Portugal), up to 50 km from the mouth, in the municipalities of Carrazeda de Ansiães, Alijó, Vila Flor, Murça and Mirandela.Sampling
Sampling was designed to cover the main habitat types for nocturnal birds in and around the lower Tua River valley affected by the Foz-Tua dam. Each sampling point was visited three times per year in winter (February) and spring (April-June), for acoustic censuses. The methodology consisted in spontaneous listening (without any playback) for five minutes, during which all "natural" contacts with nocturnal birds were recorded, followed by the emission of vocal recordings for one minute to induce audible responses of individuals of Bubo bubo, or other species. The playbacks were followed by a fixed listening time (three minutes), where all contacts with any nocturnal species were recorded. This procedure was repeated three times in each sampling point. All censuses begun 15 minutes after sunset and proceed up to two hours (maximum) after the first listening.Quality Control
All identifications were performed by qualified techniciansMethod steps
