Technodiversity Glossary

Felling, delimbing and bucking to standard industrial logs or differentiated assortments directly in the stand

Functiogram:

 

• Letting nutrients and biomass in the stand
• No transport of waste
• Low investment
• Low relocation cost

• Dangerous work, ergonomic limitations
• Extreme danger at steep terrain
• Costs of processing
• High costs of pre-skidding (logs are not bunched/stacked - follows higher cost of forwarding)

• For lowering the mass of the logs in order to ease manual pre-skidding (animal, hand)

Economic suitability

Example:

• machine costs without personal costs: 4,0 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 1
• in total: 39,00 Euro/h
  • regression line time per tree
  • b₀ = 4,0
  • b₁ (tree volume) =  22,0

Social suitability:

• S-class: no contact with forest road -> S5
• E-class: motor-manual work, very heavy and dangerous -> E2
