We compared the number of avian species detected and the sampling effort during fatality monitoring at 50 North American wind facilities. Facilities with short intervals between sampling events and high effort detected more species, but many facilities appeared undersampled. Species accumulation curves for 2 wind facilities studied for more than 1 year had yet to reach an asymptote. The monitoring effort that is typically invested is likely inadequate to identify all of the species killed by wind turbines. This may understate impacts for rare species of conservation concern that collide infrequently with turbines but suffer disproportionate consequences from those fatalities. Published 2015.

采样不足以识别受涡轮碰撞影响的物种。

我们比较了在北美50个风力发电场进行的病死率监测期间检测到的鸟类物种数量和采样工作。采样事件之间的时间间隔短且努力程度高的设施检测到更多物种，但许多设施似乎采样不足。研究超过1年的2个风能设施的物种积累曲线尚未达到渐近线。通常投入的监视工作可能不足以确定风力涡轮机杀死的所有物种。这可能低估了对稀有保护物种的影响，这种罕见物种很少与涡轮机发生碰撞，但因这些死亡而遭受不成比例的后果。2015年出版。本文是美国政府的工作，在美国属于公共领域。
