摘要

摘要监测水鸟是了解湿地栖息地健康状况的基础。然而,这种监测必须通过可靠的数据收集来进行,这些数据可以提供关于人口趋势的准确信息。通常,水鸟的监测很困难,因为筑巢地通常位于人迹罕至的芦苇丛中,而且很难通过眼睛检测到神秘物种。无人机有能力克服大多数这些问题,因为它们可以提供无法到达的地方的鸟瞰图,同时减少干扰和在野外花费的时间。本研究旨在比较一种神秘物种紫鹭的地面(传统)和无人机计数的准确性、干扰水平和管理效率。传统的监测方法只能检测到35%的无人机调查检测到的筑巢对(地面和无人机调查分别为8.0±11.8对和22.9±38.2对)。因此,两种方法之间的菌落大小估计结果一致性较差,以至于传统方法错过了无人机检测到的菌落。无人机飞行时发现的巢对没有明显的负面影响。此外,用无人机调查繁殖地的平均时间远少于传统方法,减少了六倍。这种减少,加上在进行无人机监测时没有观察到干扰,监测精度和准确性不断提高,支持将无人机作为在难以进入的地点进行人口监测研究的侵入性最小的选择。

Faster and Better: Comparison between Traditional and Drone Monitoring in a Cryptic Species, the Purple Heron Ardea purpurea
Abstract. Monitoring waterbirds is fundamental to understand the health status of wetland habitats. However, this monitoring has to be conducted by means of reliable data collection that can provide accurate information on population trends. Usually, waterbird monitoring is difficult, as nesting grounds are usually located in inaccessible reedbed, and by eye detection of cryptic species is hard. Drones have the capacity to overcome most of these problems, as they can provide with an aerial view of places otherwise unreachable, while reducing the disturbance and time spent in the field. The present study aims to compare the accuracy, disturbance levels, and managerial efficiency between ground (traditional) and drone counts of a cryptic species, the Purple Heron Ardea purpurea. Traditional monitoring methods were only capable of detecting 35% of the nesting pairs detected by the drone surveys (8.0 ± 11.8 versus 22.9 ± 38.2 nesting pairs in ground and drone surveys, respectively). Consequently, colony size estimates between methods showed poor agreement, to the point that traditional methods missed colonies otherwise detected by the drone. No apparent negative effects on nesting pairs where found when flying the drone. In addition, mean time spent to survey breeding sites with a drone was far less than with the traditional approach, down to a six-fold time reduction. This reduction, together with a lack of disturbance observed when conducting the drone monitoring, and an increasing monitoring precision and accuracy, supports the use of drones as the least invasive option for studies on population monitoring on hardly accessible sites.
