Sara McMillan.AMES, Iowa – The Iowa Learning Farms conservation webinar taking place Oct. 20 at noon will feature Sara McMillan, associate professor of agricultural and biological engineering at Purdue University. McMillan’s research focuses on the impacts of agriculture and urbanization on how nutrients flow through living systems and their physical environments. She also studies the impact on ecosystem function in transitional areas between the land and water such as wetlands, floodplains and small streams.

Iowa Learning Farms is based at Iowa State University Extension and Outreach.

In the webinar, “Ecosystem Function of Wetlands in Midwestern Agricultural Landscapes,” McMillan will draw on her field and laboratory-based approaches, as well as data-driven modeling experiences to highlight watershed ecosystem effects on downstream users. 

She will share ongoing work from her group as well as others in the Midwest who are studying the role wetlands play in an agricultural landscape. The session will also provide insights into identifying the environmental factors that control ecosystem functions to enable better management of existing wetlands, as well as inform decisions on construction or restoration of wetlands for uses including irrigation, animal watering or recreation.

“Wetlands, floodplains and small streams are hot spots that have more positive impacts on water per land area than most other land uses,” said McMillan. “These wetland ecosystems are often the most vulnerable to changing land use and climate but also have a disproportional impact on downstream users, including flood storage, water quality, biodiversity and climate regulation.”

Participants in Iowa Learning Farms Conservation Webinars are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
