EDP Foz-Tua: Dragonflies and Damselflies (Odonata) - Ecological Monitoring Program (2011-2017)

The dataset contains records of Dragonflies and Damselflies (Odonata) 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 June 2011 and August 2017 during field visits to 33 sampling points 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 for the both groups was recorded when individuals were seen or captured heard around the point in a 15-minute census.

该数据集收录了在图阿河下游流域采集的蜻蜓和豆娘（蜻蜓目）记录，这些记录包含在由葡萄牙能源公司EDP – Energias de Portugal, S.A. 主导的福兹图阿水电站生态监测计划（2011-2017）中。数据采集于2011年6月至2017年8月期间，通过对受福兹图阿水电站直接影响或间接影响的图阿河下游流域内33个具有适宜生境的采样点以及杜罗河流域的一条小溪进行实地考察时完成。对于两组生物，当在15分钟的普查中观察到或捕获到个体时，记录其出现情况。
