The dataset contains records of land birds (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 surveys made in the upper Sabor sub-basin, outside the area of influence of the dams, from February 2010 to September 2014. These points were thus used as controls to assess the impact of the Sabor Dams. Sampling was performed in selected points distributed along the Maçãs and Angueira river valleys. The presence and identity of bird species were assessed by visual and/or acoustic observation, with the support of binoculars. The records include taxa identified at the species or genus levels.

This dataset includes results of surveys made in and around the area affected by construction works complementary to the dam sites, from August 2010 to September 2014. The presence and identity of bird species were assessed by visual and/or acoustic observation, with the support of binoculars. The records include taxa identified at the species or genus levels.

Baixo Sabor: Land Birds - Construction and Reservoir Filling Phases (Sabor river valley) [2010-2014]
The dataset contains records of land birds (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 surveys made in and around the area affected by the dams, from February 2010 to September 2014.

This dataset includes results of surveys made in and around the area affected by the dams, from February 2010 to September 2014. Sampling was performed close to extant stream weirs, as well as close to locations where weirs were planned to be built in the future under the mitigation program of AHBS. The presence and identity of bird species were assessed by visual and/or acoustic observation, with the support of binoculars. The records include taxa identified at the species or genus levels.

The dataset contains records of terrestrial, aquatic and riparian birds (Aves) collected in the lower valley of River Sabor (NE Portugal), in the scope of the monitoring programs of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A.. Specifically, the dataset relates to monitoring carried out to evaluate the effectiveness of measures implemented to mitigate the impacts of AHBS. In this case, the mitigation measures refer to "MC1 - Compensatory Habitat of Vilariça Stream". The dataset includes the results of bird surveys made in the Vilariça stream from January 2013 to September 2014. Sampling was performed in selected points distributed along the stream, up to 5 km upstream of the mouth. The presence and identity of bird species were assessed by visual and/or acoustic observations, with binoculars. The records include taxa identified at the species or genus levels.

Bird species data from the UK Environmental Change Network (ECN) lowland terrestrial sites. These data were collected, using the British Trust for Ornithology (BTO)'s Common Bird Census methodology (CBC), at ECN's lowland terrestrial sites using a standard protocol. This protocol was abandoned in favour of the Breeding Bird Survey (Rennie et al (2017) UK Environmental Change Network (ECN) bird data: 1995-2015 https://doi.org/10.5285/5886c3ba-1fa5-49c0-8da8-40e69a10d2b5) in 1999; however, some sites continued to follow this protocol for a number of years after 1999 to allow comparison with the Breeding Bird Survey data. The CBC uses a mapping method in which a series of visits are made to all parts of a defined plot during the breeding season and contacts with birds by sight or sound are recorded on large-scale maps. Information from the series of visits is combined to estimate the number of territories found. Annual data are recorded but the date ranges available are variable for each site. ECN is the UK’s long-term environmental monitoring programme. It is a multi-agency programme sponsored by a consortium of fourteen government departments and agencies. These organisations contribute to the programme through funding either site monitoring and/or network co-ordination activities. These organisations are: Agri-Food and Biosciences Institute, Biotechnology and Biological Sciences Research Council, Cyfoeth Naturiol Cymru - Natural Resources Wales, Defence Science & Technology Laboratory, Department for Environment, Food and Rural Affairs, Environment Agency, Forestry Commission, Llywodraeth Cymru - Welsh Government, Natural England, Natural Environment Research Council, Northern Ireland Environment Agency, Scottish Environment Protection Agency, Scottish Government and Scottish Natural Heritage.

Bird species data from the UK Environmental Change Network (ECN) terrestrial sites. Counts of individual bird species are recorded. These data are collected, using the British Trust for Ornithology (BTO)'s Breeding Bird Survey methodology, at all of ECN's terrestrial sites using a standard protocol. They represent continuous records from 1995 to 2015 (the transects are walked twice each year). ECN is the UK's long-term environmental monitoring programme. It is a multi-agency programme sponsored by a consortium of fourteen government departments and agencies. These organisations contribute to the programme through funding either site monitoring and/or network co-ordination activities. These organisations are: Agri-Food and Biosciences Institute, Biotechnology and Biological Sciences Research Council, Cyfoeth Naturiol Cymru - Natural Resources Wales, Defence Science & Technology Laboratory, Department for Environment, Food and Rural Affairs, Environment Agency, Forestry Commission, Llywodraeth Cymru - Welsh Government, Natural England, Natural Environment Research Council, Northern Ireland Environment Agency, Scottish Environment Protection Agency, Scottish Government and Scottish Natural Heritage.
