Description:
The objective of this course is to provide geoscience students with an
introduction to the engineering aspects of forest management and to the
methods used in the harvesting of timber in British Columbia. It is
essential for forest geoscientists to be fully cognisant of the nature,
limitations, advantages and implications of forest harvesting
technology on terrain impact and its mitigation.
The course will consist of two components:
a. Lectures and invited seminars will be given by professional foresters and engineers
b. Field visits to observe varied aspects of forest harvesting techniques and operational forestry management.
Students should budget for $150 field costs (food and lodging).
- Forest Harvesting Techniques
- Ground-based systems: skidders, hoe-chucking, feller-forwarder.
- Cable systems: grapple yarding, highlead and skyline.
- Aerial systems: Helicopter logging and balloons.
- Hand logging and horse logging.
- Tailhold stumps and guylines.
- Elements of operational logging:
- Layout of cut blocks and road systems
- Partial harvests vs. clearcutting,
- Cut patterns and their effects
- Forest roads as a function of harvesting: requirements and expected loading.
- Bridges, culverts and drainage structures on forest roads.
- Forest development plans.
