Data Used
5
Data Used 1 Areas (based on Forestry Zones) Roundwood Volume (based on Forestry Zones) Planted areas per product :FES 2005/06 Age class distribution per product :FES 2005/06 Sirex affected area:Sirex Co-ordinator Roundwood Prices (based on Forestry Zones) Rotation ages per product:FES 2005/06 MAI’s :FSA Sawlogs (at roadside): LP Index, Crickmay – March 2007 Pulpwood (delivered mill): NCT – June 2007 Poles (at roadside): SAWPA - June 2007
6
Data Used 2 Volume of Processed Product (recovery rates) Product Prices (current) Crickmay & Associates Sawlogs 47%: Crickmay & Associates Pulpwood 33%: FSA, Industry Poles 95%: SAWPA Inoculation & Thinning Costs (current) Sirex infection rates:Sirex Co-ordinator Inoculation costs :Sirex Co-ordinator Thinning costs: FSA, Industry LPI, Crickmay & Assocs Sawn timber: LPI, Crickmay & Assocs Pulp: FSA, Industry Poles: SAWPA

Methodology Used
8
Basic Premises Upon Which Analysis Made The loss of any volume NOW through Sirex damage or thinnings will result in a foregone loss in volume in the future. First Premise This loss in volume will result in a foregone loss in income in the future to both the Forestry Industry AND the Forest Products Industry Second Premise
9
Methodology - Sirex Damage Determination of Foregone Volume and its Value Area affected / at risk (ha) Infection level (%) Equivalent area lost (ha) x MAI x Rot Age = m 3 /ha Future volume lost (m 3 ) x roundwood prices Future income foregone Future product volume lost (m 3 ) x recovery rates x processed product prices Age classes
10
Methodology - Thinnings Determination of Foregone Volume and its Value Area affected / at risk (ha) Thinning regime used 5%, 10% & 15% Equivalent area lost (ha) x MAI x Rot Age = m 3 /ha Future volume lost (m 3 ) x roundwood prices Future income foregone Future product volume lost (m 3 ) x recovery rates x processed product prices Age classes
11
Methodology - Thinnings Determination of Cost of Operations Area affected / at risk (ha) Thinning regime used 5%, 10% & 15% Area thinned (ha) x cost per hectare Total operational cost Age classes
12
Methodology - Inoculations Determination of Cost of Operations Area affected / at risk (ha) Infection level (%) 1-3% (33% inoculated) 3%+ (20% inoculated) Area inoculated (ha) x cost per hectare Total inoculation cost Age classes
13
Assumptions Made
14
Assumptions Made in Analysis 1 Areas at Risk Areas Affected Sawlog stands: 15 yrs and older Pulpwood stands: 10 yrs and older Other stands: 13 yrs and older Infection Rates W & S Cape (all crops): 0.1% E Cape, S KZN & KZN Mid (sawlogs): 0.5% E Cape, S KZN & KZN Mid (pulpwood): 5.0% W, S & E Cape (sawlogs/poles): 50% of area at risk W, S & E Cape (pulpwood): 100% of area at risk S KZN & KZN Midlands (all crops): 100% of area at risk
15
Assumptions Made in Analysis 2 Thinnings Recovery Rates Only pulpwood stands thinned (5%, 10% & 15% volume) Eventual loss in volume 80% (i.e. 4%, 8% & 12% loss) Thinnings occur between 4 & 7 years – all to waste Cost based on R30 per m3 Inoculations Cost per hectare (from Mondi Shanduka & Sappi) R1 100 Infection levels of 1-3% - 33% of area inoculated Infections levels of over 3% - 20% of area inoculated Sawlogs to sawn timber: 47% Pulpwood to pulp: 33% Poles to treated poles: 95%
16
Scenarios Used
17
Area Demarcation & Characteristics 1 Western & Southern Cape Eastern Cape, Southern KZN and KZN Midlands Winter rainfall area 91% sawlogs – balance poles Stable & low levels of infestation Balance of KZN, Mpumalanga & Limpopo Summer rainfall area 60% sawlogs – balance pulpwood Low to medium levels of infestation & increasing Summer rainfall area 69% sawlogs – balance pulpwood Currently Sirex free 1. Forestry Areas Divided into 3 Zones ZONE 1 ZONE 2 ZONE 3
18
Area Demarcation & Characteristics 2 2. Zones Divided into 2 Regions ZONE 1 ZONE 2 ZONE 3 Currently Affected Currently Unaffected Total Currently Affected & Unaffected
19
Scenarios 1. Based on Currently Affected Areas 2. Based on Currently Unaffected Areas Current cost / losses on areas affected Plus cost of thinnings (5%, 10% & 15%) & inoculations Potential cost / losses if all “area at risk” affected Plus cost of thinnings (5%, 10% & 15%) & inoculations 3. Basic scenarios developed ZONES 1 & 2 ZONE 3 Cost / losses if same infection levels as affected areas Plus cost of thinnings (5%, 10% & 15%) & inoculations Potential cost / losses if all “area at risk” affected Plus cost of thinnings (5%, 10% & 15%) & inoculations 3. Consolidated ZONES 1, 2 & 3

Section 2 Summary of Preliminary Results
21
Areas Involved – Current Situation Hectares Total = 688 313 ha: At risk = 279 732 ha : Affected = 90 921 ha
22
Areas Involved – RSA Hectares Total = 688 313 ha: At risk = 279 732 ha : Potential Affected = 199 432 ha
23
Estimated Volume Losses – RSA (ex Sirex Damage - Growers) M3 Ex affected = 1 315 000 m 3 : Ex at risk = 1 417 000 m 3
24
Estimated Volume Losses (ex Sirex Damage) M3
25
Estimated Volume Losses – RSA (ex Sirex Damage - Processors) M3 Ex affected = 453 000 m 3 : Ex at risk = 501 000 m 3
26
Estimated Foregone Income - RSA (ex Sirex Damage - Growers) Million Rand Ex affected = R346 million : Ex at risk = R383 million
27
Estimated Foregone Income - RSA (ex Sirex Damage - Processors) Million Rand Ex affected = R1 431 million : Ex at risk = R1 527 million
28
Estimated Foregone Income (ex Sirex Damage) Million Rand
29
Estimated Volume Losses (ex Thinnings - Growers) M3
30
Estimated Volume Losses (ex Thinnings - Processors) M3
31
Estimated Foregone Income (ex Thinnings - Growers ) Million Rand
32
Estimated Foregone Income (ex Thinnings - Processors ) Million Rand
33
Estimated Inoculation Costs Million Rand No inoculations undertaken Current Affected Area = R20 m: Area at Risk = R74 m
34
Conclusion 1 Sirex is already causing massive losses in terms of volume and foregone income for the Industry. Should it spread into those areas where it currently is not present, these losses will increase dramatically. Sirex will require a large amount of resources to be used to control it.
35
Conclusion 2 The best results can be achieved by taking action as soon as new infestations are discovered It is thus critical that an efficient and effective monitoring programme be developed and put in place ASAP
