EDP Foz Tua Large Mammals: river crossings - reference situation/early exploration phase. Compensatory Measures Monitoring Program (MC40B.1) [2012-2017]

The dataset contains records of large mammals (Mammalia) and other fauna (Herpetofauna, Aves) collected in the lower valley of the River Tua to assess the river crossing potential before (2012-winter 2016) and after (spring 2016-2017) the implementation of the Compensatory Measure MC40B.1, included in the Compensatory Measures Program (PMC) of the Foz Tua Hydroelectric Dam, promoted by EDP – Energias de Portugal, S.A. Data were collected between April 2012 and August 2017 three bridges, as well as in four natural crossings in Tua river (up the beginning of flooding phase, in late 2015), using visual prospection (ponts and/or transects), stone powder and camera trapping (2 cameras per site). Both direct (visual observation, photos) and indirect (faeces, tracks/trails) signs were used to confirm the presence of the target species/groups (the identification up to the species levels was not always possible).
