Sampling event dataset https://doi.org/10.15468/4aqk8t accessed via GBIF.org on 2023-09-29.Description
The dataset contains records of nests of cliff-nesting species of high conservation priority, namely birds of prey and Black Stork (Ciconia ciconia) (Aves) collected in the lower valley of 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. This dataset includes results of nest surveys made in and around the area affected by the dam, from May 2010 to June 2014. Data consists of observations of all nests of the target species found in the study area, which were followed throughout the reproduction period (March-August) of each year. The records include the number of young produced by each couple in each year. The target species were Golden Eagle (Aquila chrysaetos), Bonelli's Eagle (Aquila fasciata), Griffon (Gyps fulvus), Egyptian Vulture (Neophron percnopteris), Peregrine Falcon (Falco peregrinus) and Black Stork (Ciconia nigra). Additional species whose nests or potential nesting sites were also recorded, included Black Kite (Milvus migrans), Common Kestrel (Falco tinnunculus) and Eagle Owl (Bubo bubo). Due to the vulnerability of nest site locations of these species, the precision of the geographic coordinates was degraded to 0.01, according to the recommendations of Chapman & Grafton (2008). The dataset with the original (undergraded) coordinates may be provided upon request by the resource contact from EDP, who will define the terms and conditions for its use.Purpose
This dataset is part of a broader initiative whereby the company EDP - Energias de Portugal 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 lower Sabor river and its main tributaries, from the river mouth up to 42 km upstream, in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro and Macedo de Cavaleiros.Sampling
The dataset includes systematic observations of all nests detected in the breeding territories of each species. Nest surveys and assessment of the likelihood of breeding usage (confirmed, probable or abandoned) were carried out in potential nesting areas (according to the indicative behavior of adults) close to nesting cliffs. Active nests were monitored each year until the end of the breeding period, with the aim of determining the number of flying chicks for each detected couple. For each nest, records were taken of its approximate location in 1:25.000 military charts, and sun exposure, as North (N), South (S), East (E), West (W), Northeast (NE), Northwest (NW), Southeast (SE) and Southwest (SW). All identifications were made "in situ" with binoculars and telescope. Because most nests were inaccessible, observations were made from vantage points in the opposite bank. For this reason, the locations provided may either be approximate, or represent the observation point, rather than the nest coordinates.Quality Control
All individual identifications were performed by qualified techniciansMethod steps
