EDP Foz Tua: Exploration Phase - Aquila fasciata and Bubo bubo breeding sites & occasional observations of other cliff-nestig species [2018-2020]

The dataset contains records of Bonelli’s Eagle (Aquila fasciata, Aves) nests and observations of other cliff-nesting species of high conservation priority, collected in the lower valley of River Tua (NE Portugal), in the scope of the long-term Ecological Monitoring Program (PME) of the Foz-Tua Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A. This dataset includes results of nest surveys carried out at and around the area affected by the dam, from January 2018 to July 2020. Data consists of observations of all nests of the target species (and Bubo bubo) found in the study area, which were followed throughout the reproduction period (January-July) of each year. The records include the number of young produced by each couple in each year, if available. The target species was the Bonelli's Eagle (Aquila fasciata), but records were also kept of individuals of Griffon (Gyps fulvus). Due to the vulnerability of these species and their nest site locations, the precision of the geographic coordinates was degraded to 0.01, according to the recommendations of Chapman & Grafton (2008). The original (undegraded) coordinates dataset may be provided upon request by the resource contact from EDP, who will define the terms and conditions for its use.

该数据集收录了波尼利隼（Aquila fasciata, Aves）的巢穴记录以及其他具有高度保护优先级的悬崖巢居物种的观察数据，这些数据是在葡萄牙东北部的图阿河下游（NE Portugal）收集的。该数据集是在Foz-Tua水电站（AHBS）长期生态监测计划（PME）的框架下进行的，由EDP – Energias de Portugal, S.A.发起。数据集涵盖了从2018年1月到2020年7月期间，在受水电站影响区域及其周边进行的巢穴调查结果。数据包括在研究区域内发现的所有目标物种（包括Bubo bubo）的巢穴观察，这些巢穴在整个繁殖期（1月至7月）内都进行了跟踪。记录中包括了每年每对繁殖个体产生的幼鸟数量（如有记录）。目标物种为波尼利隼（Aquila fasciata），同时亦记录了秃鹫（Gyps fulvus）的个体信息。鉴于这些物种及其巢穴位置的脆弱性，根据Chapman & Grafton（2008）的建议，地理坐标的精确度被降低至0.01。如有需要，原始（未经降级）的坐标数据集可通过资源联系人从EDP处获取，EDP将定义其使用条款和条件。
