* Potential Problems Using Beaver for Restoration & Conservation

What can go wrong

Beavers can cause damage to property, such as cutting down an old oak tree.


Synopsis of Topic

We will introduce by way of discussion other approaches to encourage beaver and have the class provide their experiences in working with beaver, including what can go wrong.

Why We're Covering It

There are other means to encourage beaver to manipulate a system.  However, we also need to acknowledge the potential damage that can arrive with beaver activity.  This will help us prevent these mishaps or prepare us for backup approaches.  Failure to do this when these techniques are somewhat novel, could jeopardize future projects when restoration goes awry.

Learning Outcomes

This topics helps us with the following learning outcomes for the workshop:
  • Knowledge of past and ongoing restoration projects using beaver;
  • A working understanding of considerations in restoration designs using beaver;
  • How to manage public expectations regarding potential restoration responses involving beaver.
