1. Understanding an organism’s habitat selection and behavioural flexibility in the face of environmental change can help managers plan for future conservation of that species. Hyperabundant tundra-nesting geese are influencing Arctic environments through their foraging activities. Goose-induced habitat change in Arctic wetlands may influence the availability of habitat for numerous shorebird species that breed sympatrically with geese. 2. Here, we explore whether goose-induced habitat alteration affects shorebird breeding density and nest-site selection. Using habitat data collected at sites with high, moderate, and low goose influence, and samples collected during two periods separated by 11 years, we document the habitat characteristics influenced by geese. We describe the habitat characteristics preferred by shorebirds and relate their availability to goose influence and shorebird density. Finally, we examine whether shorebird nest-site selection has changed over time and whether shorebirds select nest ... : Proportional cover and dominant habitat type surveysHabitat surveys conducted at all shorebird nests and random sites.
