Over the past decade, the United States has seen a rapid increase in oil and gas extraction from areas where resources were previously thought to be unrecoverable, particularly the Bakken shale formation in North Dakota. The Bakken overlaps with the Prairie Pothole Region, the most critical habitat in North America for breeding ducks, where oil and gas extraction through hydraulic fracturing has the potential to impact more than a million duck pairs in the United States alone. Here, we evaluated the effect of oil and gas development on nesting ducks in 2015–2017 across 5 counties in North Dakota. Using data from ~4,000 nests we found that nest survival was higher at sites composed of a higher percentage of grassland, and for nests found closer to major roads. We found no effect of any metric of oil and gas extraction activity on duck nest survival. Using survival-corrected estimates of nest density, we found higher densities of nests closer to roads, but lower nest densities at sites surrounded by more wells. Our top-ranked model indicated that nest density was predicted to decline by 14% relative to sites with no development, given the average number of wells (3.15 wells) within 1,500 m of a site. However, within a nesting field, we found no evidence that ducks were avoiding petroleum-related infrastructure at smaller spatial scales. Our results indicate mixed effects of oil and gas development on nesting waterfowl, and highlight both the resiliency of dabbing ducks to environmental change and the need for additional research on other aspects of duck breeding biology.

靠近北达科他州的油井不会影响鸭子的筑巢成功,但会降低筑巢密度

在过去的十年中,美国从以前被认为无法开采资源的地区(尤其是北达科他州的巴肯页岩地层)开采的石油和天然气迅速增加。Bakken与草原坑洼地区重叠,草原坑洼地区是北美最主要的鸭子繁殖地,通过水力压裂法开采油气,仅在美国就有超过100万只鸭子受到影响。在这里,我们评估了北达科他州5个县在2015–2017年油气开发对巢鸭的影响。使用来自约4000个巢穴的数据,我们发现,在由较高百分比的草原组成的地点以及靠近主要道路的巢穴中,巢穴的存活率更高。我们发现任何量的石油和天然气开采活动对鸭巢生存没有影响。使用生存校正的巢密度估算,我们发现靠近道路的巢密度更高,但在被更多井包围的地点,巢密度更低。我们的排名最高的模型表明,考虑到一个站点1,500 m之内的平均井数(3.15井),相对于没有发育的站点,巢密度预计将下降14%。但是,在一个筑巢场中,我们没有发现证据表明鸭子在较小的空间尺度上避开了石油相关的基础设施。我们的研究结果表明,油气开发对筑巢水禽的混合影响,并突出了鸭鸭对环境变化的适应力以及对鸭繁殖生物学其他方面的进一步研究的需要。但在更多井周围的地点,巢密度较低。我们的排名最高的模型表明,考虑到某个地点1,500 m之内的平均井数(3.15井),相对于没有发育的地点,巢密度预计将下降14%。但是,在一个筑巢场中,我们没有发现证据表明鸭子在较小的空间尺度上避开了石油相关的基础设施。我们的研究结果表明,油气开发对筑巢水禽的混合影响,并突出了鸭鸭对环境变化的适应力以及对鸭繁殖生物学其他方面的进一步研究的需要。但在更多井周围的地点,巢密度较低。我们的排名最高的模型表明,考虑到某个地点1,500 m之内的平均井数(3.15井),相对于没有发育的地点,巢密度预计将下降14%。但是,在一个筑巢场中,我们没有发现任何证据表明鸭子在较小的空间尺度上会避开与石油相关的基础设施。我们的研究结果表明,油气开发对筑巢水禽的混合影响,并突出了鸭鸭对环境变化的适应力以及对鸭繁殖生物学其他方面的进一步研究的需要。场地500 m。但是,在一个筑巢场中,我们没有发现任何证据表明鸭子在较小的空间尺度上会避开与石油相关的基础设施。我们的研究结果表明,油气开发对筑巢水禽的混合影响,并突出了鸭鸭对环境变化的适应力以及对鸭繁殖生物学其他方面的进一步研究的需要。场地500 m。但是,在一个筑巢场中,我们没有发现证据表明鸭子在较小的空间尺度上避开了石油相关的基础设施。我们的研究结果表明,油气开发对筑巢水禽的混合影响,并突出了鸭鸭对环境变化的适应力以及对鸭繁殖生物学其他方面的进一步研究的需要。
