Abstract

The dataset contains records of bats (Chiroptera) collected in the lower valley of River Tua. Data were collected in the scope of the long-term Ecological Monitoring Program (PME) and the Monitoring Program of Mitigation/Compensation Measures (PMC) of  the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2011 and September 2017 during field visits to 91 known or presumed bat hibernation, reproduction and pre-dispersion (post-reproduction) roosts, within a 5-km radius buffer around the lower valley of River Tua. From 2012, two roosts located at >20 km from the river (deactivated railroad tunnels) were added to the sampling sites in the context of the PMC. The presence of individuals was recorded by direct observation, and all individuals were photographed whenever possible. The records include taxa identified at the species or genus level. In several occasions it was not possible to separate the individual species, so they were grouped in 15 “species complexes”, both mono-specific and multi-specific. 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 (undegraded) coordinates may be provided upon request by the resource contact from EDP, who will define the terms and conditions for its use.

General description

Purpose: This dataset is part of a broader initiative whereby the company EDP - Energias de Portugal S.A. will made available biodiversity data collected during impact assessment and biological monitoring studies.

Project details

Project title: EDP Foz Tua: Bat Roosts - Ecological & Compensatory Measures Monitoring Programs [2011-2017]
Personnel: Hugo Costa, Nuno Salgueiro, Sílvia Mesquita, Miguel Mascarenhas, Ana Teresa Marques, Helena Coelho, Luís Braz, Rui Gonçalves, Cláudia Ferraz, Susana Batista, Sérgio Bruno Ribeiro, Dárcio Sousa, João Paula, José Oliveira, Marco Caetano, Rui Silva, Bárbara Monteiro, Pedro Pereira, Margarida Silva, Catarina Ferreira, Fernanda Pereira, Tiago Neves, Joana Magalhães, Fernado Romão, Margarida Augusto, Mário Carmo, João Santos, Luís Queirós, Mafalda Moreira, Joana Santos, Tiago Múrias
Funding: The work was funded by EDP - Energias de Portugal, S.A.
Study area descriptions/descriptor: The study was conducted in part of the sub-basin of river Tua directly or indiirectly affected by the construction of the Foz-Tua Hydroelectric Dam. The sampling included all known and potential 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 36 km from the Tua mouth.
Design description: Thje objective of the study was to monitor the fate of bats roosts (hibernation and/or reproduction, and pre-dispersion periods) and associated bat populations in the area of the Foz-Tua Hydroelectric Dam, centered in a 5-km radius buffer around the river, during its construction (2011-2015) and subsequent flooding (2016-2017). The objectives also included the monitoring of bat population trends in 2 deactivated railroad tunnels located outside the study area (20 km distant), whose conditions for bats were improved in the scope of the Mitigation/Compensation Program of the Foz-Tua dam (2015-2016).

Methods

Method step description: To be completed
Study extent description: The data were collected within a 5-km radius buffer around the lower valley of River Tua (Northeast Portugal), up to 36 km from the mouth, in the municipalities of Alijó, Carrazeda de Ansiães, Vila Flor, Mirandela, Sabrosa and Bragança. There were also two additional sites surveyed at >20 km from the river.
Sampling description: Sampling was designed to cover all known and potential bat roosts in the study area, including railroad tunnels, caves, mines, wells, bridges and all sorts of buildings. A place was considered to be a roost when the presence of bats was confirmed, either by direct observations or by indirect evidences (e.g., faeces, urine stains, etc.). Each roost was visited once or twice per season, in the hibernation (January-February), reproduction (April-August) and pre-dispersion (September-October) periods, depending on the year.

All roosts were searched for the presence of bats by two observers, which recorded all individuals seen. The time spent in each roost varied with 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. All bats were photographed whenever possible, not only to build a photographic database, but also to allow a “a posteriori” identification of individuals that raised doubts, or to count large groups that could not be accurately counted in a suitable time in the field.
Quality control description: All identifications were performed by qualified technicians
