Bat species data from the UK Environmental Change Network (ECN) terrestrial sites. The count of individual species is recorded. These data are collected while walking a defined transect using a bat detector at ECN's terrestrial sites using a standard protocol. They represent continuous records (the transects are walked four times each year) from 1993 to 2015. 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.

This dataset provides nightly values for activity of two Pipistrelle bat species (Pipistrellus pipistrellus and Pipistrellus pygmaeus) with associated weather and weekly potential food resource data. Bat activity was recorded continually on three ultrasonic acoustic loggers for 185 days (31/04 to 01/11/2014) in an upland pine forest in the Cairngorms National Park, Scotland.

The dataset contains records of bats (Chiroptera) collected in the lower valley of River Sabor, in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2012 and August 2014, during field visits to 12 known bat hibernation, reproduction and pre-dispersion (post-reproduction) roosts with restricted access (caves and mine entrances). These roosts were located within a 5-km radius buffer around the lower valley of River Sabor. The presence and identity of the bat species were assessed by acoustic sampling of the echo-location calls emitted in flight. The records include taxa identified at the species, genus, family or order level, as well as several potential species present in 2 acoustic “species complexes”. Due to the vulnerability of the roost locations, 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.

The dataset contains records of bats (Chiroptera) collected in the lower valley of River Sabor, 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. Sampling was carried out between August 2008 and September 2014 in selected sampling points, in the framework of the regular monitoring of feeding habitats for Chiroptera. As part of the monitoring program of Compensatory Measures (MC 5.7), sampling was also carried out between July 2010 and September 2104 close to small weirs located in the tributaries of the River Sabor, above the area to be flooded by the reservoirs. The latter sampling included both extant weirs and locations where weirs were planned to be built in the future for improving feeding resources for bats. Overall, regular field sampling was performed at a total of 97 sampling points within a 5-km radius buffer around the limits of the area flooded by the reservoirs in the lower valley of River Sabor. The presence and identity of bat species were assessed by acoustic sampling of the echo-location calls emitted in fligth. The records include taxa identified at the species, genus, family or order level, as well as groups of species that share common calls but cannot be identified to any taxonomic level, and that were thus assigned to acoustic “species complexes”.

The dataset contains records of bats (Chiroptera) 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. Specifically, this dataset includes results of surveys made in the scope of the monitoring of the project of Compensation Habitat of Vilariça valley for Chiroptera (MC1). Data were collected between April 2013 and August 2014, during field visits to 2 selected points located along the Vilariça stream, a tributary of the Sabor river, located near its mouth. The presence and identity of bat species were assessed by acoustic sampling of the echo-location calls emitted in fligth. The records include taxa identified at the species, genus, family or order level, as well as groups of species that share common calls but cannot be identified to any taxonomic level, and that were thus assigned to acoustic “species complexes”.
