  1. Investing in Forest Fertilization: tools, measures, analyses By Ralph Winter Forest Practices Branch July 25, 2005

  2. Objectives • review the growth and yield tools that we use • review stand level outcomes • review forest level outcomes • review industry comments • summary

  3. Ministry has comprehensive growth and yield tools • These tools help integrate biological information with treatment effect and stand management actions • Tree and Stand Simulator (TASS) and TIPSY are the primary tools to evaluate stand treatments

  4. Typical TIPSY output

  5. Volume/age information from TIPSY

  6. Volume/age information from TIPSY

  7. Typical TIPSY output

  8. Analysis of a fertilized spruce plantation at age 50 compared to untreated. A volume response at age 70 of 16 cubic metres.

  9. Analysis of a fertilized spruce plantation at age 35 compared to untreated. A volume response at age 70 of 17 cubic metres.

  10. The Internal Rate of Return for fertilization is dependant on time to harvest 5% IRR can be achieved if time to harvest is less than 35 years - 30 to 40 year Govt bond rates are at 4.73% Spruce plantaions - 100 km - SI 19.6

  11. Silviculture affects conditions produced at the forest level • current AAC is maintained longer treated harvest schedule LRSY treated LRSY m3 (millions) 2.5 2.0 1.5 1.0 untreated harvest schedule 0.5 0 6 7 8 9 10 11 1 2 3 4 5 decades

  12. Allowable cut effect - sustain harvest levels longer and 5.9 % increase in the midterm Cranbrook TSA

  13. Forest level analysis - TFL 52

  14. TFL 52 comments

  15. TFL 52 comments

  16. direct and indirect jobs income tax generated wildlife habitat biodiversity Log quality profiles changes in harvest net revenue impacts stumpage Other factors that have been analysed in comprehensive silv strategies

  17. Summary • fertilization research is included in GY & forest models. • models are used to forecast a variety of measures including volume, value, revenue, ROI and jobs • analyses indicate that fertilization can have a positive impact when done at the right sites for the right reasons • every tree to be harvested in the next 20-60 years is in the ground today. Fertilization treatments need to commence soon if significant short or mid term timber supply improvements are desired • operational support from industry for forest fertilization

  18. Industry comments in FIA submissions • “Increase wood volume and utilization. This will increase product output and reduce recovery costs. Also, reduce rotation age” - Bonaparte Kamloops TSA • "Fertilization is a silviculture treatment that can be effectively used to increase the merchantable yield and value of established forests". - TFL 14 • “Operational Fertilization programs have been recognized as a high priority for the future timber supply issues through the TSA silviculture analysis” - Westfraser
