Forestry and Resource Management
2
Case study: Clayoquot’s Big Trees
1993- Canada’s largest act of civil disobedience -Timber fueled the economy -Protesters opposed the logging of Canada’s oldest forests 1995 –the government recommended reducing harvests and retaining old growth trees The government reversed its policies
3
1998 – the timber company agreed to limited logging and began using environmentally friendly practices -ecotourism began to thrive: fishing, kayaking, whale watching, etc. -site became a United Nations International Biosphere Reserve -trees were worth more alive than cut down
4
True or False: Renewable resources cannot runout.
Resource Management - managing resource harvesting so the resource is not depleted (sustainable use) Renewable resources: soil, fresh water, animals, timber
5
Management Approaches
Maximum sustainable yield (MSY) – maximize harvest without reducing future harvests Keep the population below its carrying capacity Disadvantages: trial and error, often results in overharvesting and ecosystem changes
6
2. Ecosystem-Based Management
Harvest resources in ways that minimize impact on ecosystems Disadvantages: - ecosystems are complex, it is difficult to determine the best plan - often results in inconsistent management
7
Assess Design implement
3. Adaptive Management - Test different approaches, customize based on the results Assess Design implement Monitor Evaluate Adjust Disadvantages: Time consuming and complicated

What do you think? What management approach would you follow?
You have just become supervisor of a national forest. Ten percent of it is old growth forest. Your managers are split among preferring maximum sustainable yield, ecosystem-based management, or adaptive management. What management approach would you follow? 2. Come to a consensus in your group, defend your choice.
