Background
I grew up in upstate New York, but I moved to Michigan in 1999 to attend graduate school and have lived here ever since. I am currently a Research Specialist with the Wildlife Division of the Michigan Department of Natural Resources. I specialize in population monitoring (through surveys and modeling) and provide support to the Division for data analysis, data management, survey design, and research into new data collection and analysis techniques. I work with species as diverse as butterflies, deer, bear, bobcat, and waterfowl, although the animals I handle are rarely anything more substantive than a record in a database. I don’t know a walleye from a salmon (except on my dinner plate), so I’m grateful to the QFC for accepting a wildlifer into their ranks as I explore the application of common fisheries population analysis techniques to wildlife populations.
Research
My research project is an application of statistical catch-at-age assessment (SCAA) techniques to data collected from bears harvested in Michigan since 1989. The Michigan Department of Natural Resources relies on estimates of bear population size as a factor in setting hunting quotas. The quota system is designed to help achieve the primary bear management goal of maximizing recreational opportunities for hunters while maintaining a stable population. A SCAA may provide an alternative to the labor-intensive capture-mark-recapture techniques currently used to monitor bear populations. It will also provide insight into other demographic parameters such as natural mortality rates, harvest rates, and recruitment.
