Proximity to oil wells in North Dakota does not impact nest success of ducks but lowers nest densities

Nesting data were collected by a graduate student and teams of technicians. Briefly, we drove ATVs parallel through a field with a chain strung between them. When the chain dragged over the top of a duck nest, the hen flushed and we located and monitored the nest. Data entry from nest cards to Excel, analysis in ArcMap, R, and MARK.
