Midterm Flashcards
Define forest management
the practical application of scientific (environmental), economic, and social values to the working and administration of a forest resource toward specified objectives.
Components of monitoring forest operations include:
- forest inventory
- AAC vs actual harvest volume
- road development and reclamation
- reforestation success
- utilization of wood fiber
- processing facility operation
Components of monitoring forest ecosystem conditions include:
- Forest health: insect, disease, fire
- Soil and water condition
- Biodiversity
- Old growth forests
- Land composition
- wildlife, fisheries etc.
Describe sustainable forest management.
An ecological based approach to forest management.
Involves:
- education, research, and professional practice
- public education and public input
- cutblock design to mimic natural disturbance
- SFM certification
- integrated resource planning and operations
What are the 3 forest management values?
- social
- economic
- environmental (scientific)
What are some economic values of forest management?
- jobs
- sales within Canada
- exports (largest $$)
What are some environmental values?
- clean air, water, carbon sequestration, soil conservation
- wildlife habitat
- forest health (insect, disease, fire)
- old growth forests
- appropriate landscape mosaic
What are some social values?
- cultural, spiritual
- food, shelter, medicine
- recreation
- intrinsic value
What is the problem with the sustainability model?
All values are interconnected and dependent on each other.
- economy is human manufactured
- basic needs for food, water, shelter are met by our environment
- these subsystems are driven by human needs and/or wants but are limited by the environments capacity to provide
What are the different scales of operation within forestry?
Spatial Scales
- regional > subregion > landscape > stand > microsite
Temporal Scales (time.. in years)
Define “stand”.
A stand is a community of trees sufficiently uniform in age, species, and arrangement as such that it is distinguishable from adjacent stands.
What is primary forest ecosystem succession?
Breaking down, freeze-thaw cycles, organic material, involves development of NEW community where one has not existed before.
What is secondary forest ecosystem succession?
involves REdevelopment of a forest community after disturbance such as fire, flood, logging
What is the edatropic grid?
moisture and nutrient regime of ecosystem types. show a specific composition of vegetation which is a function of that moisture and nutrient regime
Briefly explain the forest development model.
- Establishment - post-disturbance stand initiation
- Thinning - pioneer species thin out due to competition for moisture and nutrients
- Transition - shift in overstory composition as shade tolerant understory species move into the overstory
- Shifting mosaic - a stable, self-perpetuating climax community.
