Presenters

Cassandra Allsup, Ph.D.

University of Wisconsin, Forest Mycorrhizal Ecologist

Cassandra Allsup’s research focuses on using soil microbes to increase forest trees’ resilience to climate change. She investigates the impact of fungi in roots, mycorrhizal fungi, on forest trees in drought conditions and altered water availability. She runs several field and greenhouse research projects at Allerton Park in Monticello, Il. Additionally, Allsup is responsible for the Forest Fungi Project, a community science project that collects roots and soils of forest trees in the eastern U.S. The project’s aim is to educate the public on the importance of soil microbes and to determine what climatic factors and host tree species determine where mycorrhizal fungal species live. Her research, Migration of soil microbes may promote tree seedling tolerance to drying conditions, was published in the journal Ecology in 2019
