Content Detail

Explore the interactions that drive ecosystem function and learn to identify plants, animals, and fungi in relation to ecological habitats. 

By developing knowledge of ecological food webs and species interdependence you will have a better understanding of how to manage natural areas to support biodiversity. We will discuss influential variables that determine habitat quality and shape an ecosystem, such as light, water, fire, and herbivory. An emphasis on the cyclical nature of the seasons and life history of native species will allow insights for short-term and long-term natural areas management. 

The online component of this class is self-guided and can be completed wherever you have access to a computer, at your own pace. Online assignments are due before the session.

The class will spend an afternoon outdoors and on-site exploring ecosystems at the Arboretum to discuss factors influencing these habitats and restoration practices.
