characteristics

• Vegetation

• Soil

• Forest site type class (FC)

• Forest site type group (FG)

• Forest site type (FS)

• Forest type (FT)

Units

Forest site type

• The areas with the same reaction of vegetation

to management operations of forestry (similar

natural conditions: climate, soil, hydrology)

• Forest site type can be the same while forest

type is changing

• Change of forest types: succession

Stand dynamics• No change in forest site type

• Change can happen in forest type in old multi aged phase
