By the end of this case study, you should be able to:1. Synthesize biological information related to a

conservation topic.2. Apply ecological principles to a current conservation

issue.3. Assess the appropriateness of a proposed

management strategy based on biological evidence.4. Determine the pros and cons of culling a wolf

population in Alberta to protect a declining caribou population.

5. Discuss potential challenges of implementing biologically focused management plans.

Where is this issue taking place?

“Environment Canada had to be dragged into court before it came up with a recovery strategy for Canada's endangered woodland caribou”

(Max Paris, Environment Unit, VIDEO CBC News: Feb 22, 2012) 4

What is the concern over the caribou population?

What are the threats to the caribou population?

What is the management strategy being proposed?

Rachael Mercer is a biologist who has been working at Environment Canada for 6 months. She completed her undergraduate ecology degree and worked at an environmental consulting company in oil and gas for 2 years. Now, as part of the Environment Canada team, she is responsible for determining if culling wolf populations is a viable LONG- TERM strategy for the conservation of caribou.

What should Rachael tell the minister? Is a wolf cull a viable long-term caribou

conservation strategy? Why or why not?
