Reengineering Italian Forestry Statistics

• Revision of wood categories and aggregates for
  statistical purposes

Scenario

• New wood process techniques and technologies
• New Rules and Regulations (EU)
• Needs of new statistical wood aggregates
  conforming with national and international
  classification and standardisation rules (Uni, EN
  etc.)
• Needs of quantitative standards for wood
  aggregates in statistic surveys
• Data supplying of the JFSQ

3
Surveys to be reengineered

• Survey on wood removals from forest area
• Survey on wood removals from other wooded area
• Survey on prices of wood product aggregates
  (prices of wood, free at border of forest)

4
Criteria for the new statistical classification

• Quantitative standards for roundwood
• CN-explanatory notes, new sawlogs definitions
  adopted by CCC (EU OJ C 256 23/10/02)
• Standardisation rules (UNI, EN)
• Uses of wood

5
Criteria for the new statistical classification

• Uses of wood

• uses of wood requiring processing
• when future uses require processing,
  classification takes in to account the kind of
  process to which wood shall be submitted. Woody
  raw materials values and prices can strongly
  depend on kind of process

• uses of wood requiring no or minimum processing
• poles, beams for construction, housing etc.
• other wood such as that used for posts, fencing,
  pitprops tanning, match blocks etc..

6
Criteria for the new statistical classification

• Uni standardisation rules taken as reference

• UNI 3512 - Pine and Larch poles for telephone
  lines - common type
• UNI 3513 - Pine and Larch poles for telephone
  lines - heavy type
• UNI 3514 - Cestnut poles for telephone lines -
  common type
• UNI 3515 - Cestnut poles for telephone lines -
  heavy type

7
Criteria for the new statistical classification

• New sawlogs definitions adopted by CCC

• Sawlogs are characterised by physical properties
  such as
• cylindrical and straight-grained without major
  bending
• a diameter of not less than 15 cm
• sawn lengthways for manufacture of sawnwood,
  cross-ties, or used for production of sheets for
  veneering (mainly by peeling or slicing).

8
Criteria for the new statistical classification

• Quantitative standards for roundwood

• Dimensional standards minimum diameter (cm),
  roundwood length (m)

9
Industrial processing of roundwood(types of
processes classified by decreasing market value
of raw material - wood)
10
Industrial processing of roundwood(types of
processes)

• Slicing

• Peeling

11
Industrial processing of roundwood(types of
processes)

• Sawing

• Chipping

List of units

• Cubic metres under bark (m3) for all wood
  removals

• Euro per cubic metres (/m3), for prices of all
  wood aggregates
