Bob Emery
(Retired - 2021)
Helped our understanding of the impact of landscape and environmental change on waterfowl; evaluated the restoration of large marsh complexes.
Bob joined DUC in 1990. He worked on the Prairie Habitat Joint Venture Assessment Project and oversaw data collection for IWWR’s Spatial and Temporal Variation in Nesting Success of Prairie Ducks study: two long-term waterfowl research projects. The information compiled from the studies has been used to guide DUC’s upland habitat programs across Prairie Canada and the results continue to provide key feedback to enhance conservation program delivery.
Most recently, Bob was involved in evaluating the restoration of Delta Marsh, a large, freshwater coastal wetland on the south shore of Lake Manitoba.
