Course Description

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 which 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 and in-person sessions complement each other; please plan to complete the class materials online before coming to the field session. This class can be taken as a component of the Natural Areas Conservation Training Program in natural areas management.
