Technodiversity Glossary

Limbs are to be cut by axe or comparable knives: with one cut the branch should be separated - therefore more suitable for younger trees and conifer species 

Functiogram:

Advantages

• Dynamic work as contrast to static, noisy and vibrating work with chainsaw
• Easy done by workers who did not have experience with chainsaw
• Low investment
• Low/no relocation cost

• Diameter of branch max 3 cm ?
• No. of branches, best if only few branches per tree
• Heavy physical effort/workload

• At first thinning in regions with low wage levels

Economic suitability

Example:

• machine costs without personal costs: 0,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 1
• in total: 35,00 Euro/h
• regression line minutes per tree
  • b₀ = 4,0
  • b₁ (tree volume) = 10,0

Social suitability

• S-class: 
  • in the stand or on the trail no contact with the forest road -> S5
  • processing on the forest road -> S2 
• E-class: manual work, very heavy and dangerous -> E1
