  1. Criterion 3 Maintenance and encouragement of productive functions of eucalyptus J-N Marien, AFOCEL Pedro Lencart, CELBI Clara Araújo, CELBI Juan Picos, AFG Nuno Borralho, RAIZ Paco Soria (PECADOR) Évora, Jan 22, 1999

  2. Proposed Indicators 31. Wood production per hectare 32. Wood production in a region 33. Growth-harvesting balance 34. Appropriate management plans in place 35. Use of genetically improved stock 36. Importance of non-wood products

  3. 31. Wood production per hectare • Operational indicator • Wood MAI (u.b.) at rotation age • PICL • Forest inventory plot or total stand harvested volume • ML • Stand level • Representativity • FMU

  4. 31. Wood production per hectare • Methodology • Growth models using forest inventory data • Wood harvested from company land • Costs • Low • Pros/Cons • Useful for managers, simple • High year to year variation (e.g. climate)

  5. 32. Wood production in a region • Operational indicator • Total standing volume • PICL • Forest inventory plots • ML • Region • Representativity • Region • Methodology • Forest inventory • Costs • Low

  6. 33. Growth-harvesting balance • Operational indicators • Total annual volume increment (ub) • Total volume purchased by industries • PICL • Regional or national inventory plot • Industries • ML • Regional or national • Representativity • Regional or national

  7. 33. Growth-harvesting balance • Methodology • Regional or national forest inventory results • Industry statistics • Costs • Low • Pros/Cons • Simple • National forest inventories are only available every 5 to 10 years • Often unreliable source of purchases

  8. 34. Appropriate management plans in place • Operational Indicators • Proportion of eucalypt stands under management plans • PICL • FMU • Representativity • Region • Costs • Low

  9. 34. Appropriate management plans in place • Methodology • Areas from national forest inventory • Areas under projects approved and supervised by Government Forest Departments • Pros/Cons • Compliance to plans is assumed • Difficult to define what is appropriate

  10. 35. Use of genetically improved stock • Operational indicator • Ratio of selected plants produced and total plants produced, as reported by nurseries • PICL • Nursery statistics • Representativity • FMU or Region • Costs • Low

  11. 35. Use of genetically improved stock • Methodology • Nursery statistics • Pros/Cons • Most plants coming from few large nurseries • In some years number of plants produces very different from areas planted

  12. 36. Importance of non wood products • Operational indicators • Percentage surface with non wood use • PICL • Property or estate • Representativity • Region • Costs • Depend on level of accuracy required

  13. 36. Importance of non wood products • Methodology • Specific survey to forest owners by region • Some statistics available in companies • Pros/Cons • Difficult to estimate areas for most small scale forest owners. Only reliable with companies and organized forest associations
