The dataset contains records of bats (Chiroptera) collected in the lower valley of the River Tua and included in the Baseline (2008-2009) and Complementary (2010) Studies of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between November 2008 and April 2010 during field visits to 27 known or presumed bat roosts used for hibernation and/or reproduction, within a 15-km radius buffer around the Tua valley. The presence of individuals was recorded by direct observation. When the identification raised doubts, or the numbers were too high to allow individual examination, the specimens were photographed for later identification. The records include taxa identified at the species or genus level. In several occasions it was not possible to separate the potential species of the genus Myotis, so they were simply included in 2 “species complexes”: “large” Myotis (2 species) and “small” Myotis (5 species).

The data were collected within a 15-km buffer around the Tua lower valley (Northeast Portugal), up to 50 km from the mouth, in the municipalities of Carrazeda de Ansiães, Vila Flor, Alijó, Mirandela and Sabrosa.
Sampling was designed to cover all known and presumed bat roosts in the study area, including railroad tunnels, caves, mines, wells and all sorts of abandoned or little used buildings. A place was considered to be a roost when the presence of bats was confirmed, either by direct observations or by indirect evidences (eg., faeces, urine stains, etc.). Each roost was visited once in winter (January-February, hibernation period) and once in spring (April, reproduction period) of 2010. In 2008-2009, only a subset of the sites (railroad tunnels) were visited.
All potential roosts were searched for the presence of bat colonies by two observers, which recorded all individuals of each species detected. The time spent in each refuge varied according to the number of bats present, and the accessibility conditions.
Species identification were usually made “in loco”, with the aid of head-torches, binoculars and field guides. When the visual identification raised doubts, or the numbers present were too large to be identified in a suitable time, photographs were taken to be identified later. Sometimes, reliable counts were not possible (e.g. due to the packing of the groups), so only the presence of the species was recorded.
All individual identifications were performed by qualified technicians

The dataset contains records of bats (Chiroptera) collected in roosts along the lower Tua River, and included in the Baseline (2008-2009) and Complementary (2010) Studies of the Environmental Impact Assessment of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between November 2008 and April 2010, during field visits to 27 known or presumed bat roosts (caves, mines, tunnels, bulidings, etc) used for hibernation and/or reproduction, within a 15-km buffer around the River Tua lower valley. The occurrence of the target taxa was documented through 907 observation events. In total, 11 taxa were identified, of which nine to the species rank and one to the genus rank. The “species complexes” of Myotis could potentially add 2 more species to the list. The most common species (>100 records) were Miniopterus schreibersii (357 records) and Myotis nattereri (207 records). The species complex of the “large” Myotis (Myotis myotis and M. blythii), with 120 records, was also significant.
The work was funded by EDP - Energias de Portugal, S.A.
The study was conducted in part of the sub-basin of river Tua, prior to the construction and subsequent flooding of the lower part of this river’s valley by the Foz-Tua Hydroelectric Dam. The sampling included all known and presumed roosts located in the flooded area and those found in a 15 km radius buffer around the future reservoir banks (caves, mines, tunnels, buildings, etc.), and up to a length of about 50 km from the Tua mouth.
The objective of the study was do document the usage of known and presumed bat roosts in the Tua lower valley before the dam construction, and to gather quality data to support the design and implementation of mitigation and/or compensation measures.
