Technodiversity Glossary

After measuring and decision where the optimal cuts have to be set, the trunk is cut into 2 or more pieces, (nearly) each of them marketable assortment.

Functiogram

• To separate assortments, lend them to different customers
• Enable collecting machines (like forwarder) to collect , lower damage in stand and on soil

• Costs
• Therefore only available after pre-skidding

• Separating logs to different assortments
• On skid road = separate forwarding
• On forest road=separate storage
• Poplar plantations in Italy (buyer-marked)
• High-value assortment production, customer-driven grading (veneer)

Economic suitability

Example:

• machine costs without personal costs: 4,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 1
• in total: 39,00 Euro/h
• regression line minutes per tree
  • b₀ = 5,0
  • b₁ (tree volume) = 3,5

Ecological suitability

• Ecogram 

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: motor-manual work, very heavy and dangerous -> E2
