A climate and soils that are appropriate for the type of trees are required.
Problems- poor forestry practices and soil erosion
What are resource(s) needed for commercial fishing
Naturally occurring fish stocks needed
Problems- overfishing and pollution in water
What are GDDs?
GDDs (growing degree days)- a measure of how warm the growing season is in a given location. The higher the GDD the warmer the climate and the wider range of crops you can grow.
What’s a CLI?
CLI (Canadian land inventory)- 7 classes that classify the land soil in Canada and how well it is for farming. Only classes 1-3 are good enough for farming commercial crops (5%)

Extensive- large areas of land that require small amounts of labour.
