In this activity, students will use data from natural parks to examine terrestrial trophic cascades. Concepts will then be applied to examples in freshwater ecosystems.

Despite the focus on terrestrial trophic cascades, the material was easy to apply to the water ecology course I utilized it in. Students were then asked to apply the concepts to algae we were learning to identify and their predators in freshwater systems.
