    This dataset is the output of a national waterbird monitoring programme coordinated by ICNF that collects information on the number and distribution of waterbirds at wetland sites in Portugal and is part of the International Waterbird Census project (African-Eurasian Waterbird Census – Europe). The dataset consists of annual waterbird counts, undertaken from 2000 to 2013, of species regularly encountered at wetlands and observed in all types of natural and man-made wetlands in mainland Portugal. In this dataset there is a record of 84 waterbird species, 20 families and 11 orders (Accipitriformes, Anseriformes, Charadriiformes, Ciconiiformes, Gaviiformes, Gruiformes, Pelecaniformes, Phoenicopteriformes, Podicipediformes, Strigiformes, Suliformes).

    The dataset contains records of Butterflies (Lepidoptera) collected in the lower valley of the River Tua, and included in the Ecological Monitoring Program (2011-2017) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between July 2014 and August 2017 during field visits to 33 sampling transects with favorable habitats on the area of the lower Tua valley directly or indirectly affected by the Foz Tua dam, and in a small stream of the Douro basin. The occurrence of the target species was recorded when individuals were seen or captured in the selected transects.

    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.

    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.

    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). 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.

    This dataset includes all the Orthoptera species recorded during a study performed in 2014 and 2015 mainly in Castro Verde Special Protection Area (SPA), southern Portugal, and is the first Orthoptera inventory conducted in the area. Orthopterans were visually recorded along transects placed in 61 sites, each composed of one forest plantation and one adjacent fallow field and. A total of 35 Orthoptera species was recorded, distributed among six of the 11 families known to occur in Portugal. Two species are recorded for the first time for Portugal: Dociostaurus hispanicus Bolivar, 1898 and Euryparyphes terrulentus (Serville, 1838). Furthermore, Platystolus martinezi (Bolívar, 1873), first recorded around 100 years ago in Portugal, is now recorded for the second time. Some of our records complement the current knowledge on species geographic distribution in southern Europe. Seven species expanded their known distribution to the south-westernmost location in Europe: Dociostaurus hispanicus, Euryparyphes terrulentus, Platycleis falx (Fabricius, 1775), Platycleis intermedia (Serville, 1838), Platystolus martinezi, Sphingonotus lluciapomaresi (Defaut, 2005) and Tylopsis lilifolia (Fabricius, 1793).
