  1. What is biological diversity?

  • Economic importance of biodiversity

  • Ecological importance of biodiversity

  • Ethical or cultural importance of biodiversity

  • Biodiversity in BC

  • BC's biodiversity at risk

  • How can we manage biodiversity?

  1. Two approaches to forest management

  • Ecosystem or coarse filter approach

  • Specific-specific or fine filter approach 


Learner outcomes



On completion of this module, you will be familiar with managing forests for biodiversity

  1. Describe biological diversity

  2. Discuss two approaches used in forest management

Pre-reading questions



The following questions will determine how much you already know about managing forests for biodiversity. It is suggested that you use a mind map to assist you in remembering.

When you have completed the module, return to your mind map and add new facts or ideas, and change or modify those that may be incorrect or need to be updated.

Use a different color of pen so it is obvious what you have added, modified, or changed. This is intended to be a positive experience.
