Abstract Conservation partners are concerned that oil and gas development in the Prairie Pothole Region may reduce the abundance of breeding duck pairs using associated wetland habitat. We conducted wetland-based surveys for breeding pairs of 5 species of dabbling ducks in the Bakken oil field during 2015–2017 across a gradient of oil and gas development intensity to test the hypothesis that the abundance of breeding duck pairs on survey wetlands would decrease as the development of oil and gas resources increased. We included covariates traditionally used to predict breeding duck pairs (i.e. wetland size and class) and a spatiotemporal index of disturbance when developing zero-inflated Poisson models relating pair abundance to environmental predictors. Similar to past analyses, pair abundance was strongly associated with wetland size. Our results were mixed and suggested that the abundance of early and late nesting species was positively and negatively related, respectively, to an index of disturbance that was largely driven by oil and gas development. Regardless of the direction of the relationship, effect sizes were small and not considered biologically significant. Our findings indicate that in our study area, strategies to conserve wetland resources for breeding duck pairs should not deviate from previous prioritization metrics within the range of oil and gas development we observed. We believe that our findings may have implications to similar landscapes within the Bakken.

SynopsisThe island of Islay posssesses by far the largest population of wintering wildflowl in the Inner Hebrides; there are 18,000-20,000 barnacle geese Branta leucopsis and 4,000 Greenland white-fronted geese Anser albifrons jiavirostris. There is also a small flock of greylag geese A. anser. Most of the commoner dabbling and diving ducks spend the winter in small numbers, with a flock of 1,000 scaup Aythya marila the most important. A few hundred pairs of eider Somateria mollissima breed, and up to 3,000 wintering or moulting birds have occurred offshore. Other breeding duck are few in number, including up to five pairs of common scoter Melanitta nigra. Whooper swans Cygnus cygnus spent the winter in the past but are now common on passage only. Barnacle geese have trebled in numbers in the last twenty years, leading to complaints of agricultural damage, and a subsequent increase in shooting and disturbance followed by a recent decline in numbers. Annual data on populations, productivity and losses are presented. Greenland white-fronted geese have varied less in numbers, but shooting has increased and the situation is reviewed. All other wildfowl occurring on the island are dealt with briefly.
