Dr. Zimmerman joined WDFW in 2008. She leads the Wild Salmon Production Evaluation Unit which is a team of biologists and technicians studying salmonid populations across western Washington. Mara is a field biologist at heart with a background in aquatic ecosystems, community ecology, and multivariate statistics. Her background in fish ecology has taken her on a journey from darters in the North Carolina piedmont, to sticklebacks in Michigan’s Upper Peninsula, to lake trout in large lakes of North America. She currently studies the survival and life history diversity of salmon and steelhead in Washington State where she applies her ecological training to the applied issues of fisheries management. Her strength is as an empirical scientist and she welcomes the opportunity to better understand fish populations by integrating ecological, life history, physiology, and genetic information.
