Synopsis of Topic
We will cover both the physical (hydrogeomorphic) and ecological feedbacks of beaver dams.
Why We're Covering It
We need to understand the feedbacks and ecosystem services provided by beaver dams in order to develop appropriate restoration and conservation objectives around these.
This topics helps us with the following learning outcomes for the workshop:
- An appreciation of beaver ecology and the complex feedbacks between beaver activity, hydrogeomorphic responses, riparian vegetation and fish ecology
