Information Gaps See abstract for details – lets dig into just one of them here: Web Meeting Ideas Fall into Three Broad Themes August 16, 2013 What Have We Learned: Fertilization vs Rehabilitation Treatments – which one? 3 Preferred Strategy Expenditures (Williams Lake) Web Meeting • Prioritize Rehab Treatments in short term because Fert Treatments can wait (but do both). August 16, 2013 Quesnel and Williams Lake TSAs 4 Web Meeting • Rehab has potential to provide merchantable volume for mills at the time of treatment AND increase the effective landbase in the long term. • Example – a dead Pl stand with 35m3/ha of green spruce scattered throughout is currently uneconomic and not expected to amount to much in next 80 years. If rehabbed now (FLTC or ITSL) it provides 35 m3/ha of merch volume into the timber supply + capture the sites potential with a new managed stand. • Costs to treat are offset by realized merch volume. August 16, 2013 Why Rehab over Fert? 5 Web Meeting • Limited number of currently suitable stands. • Risk of loss reduced and ROI increased when fert done closer to harvest. • Still plenty of time to treat stands prior when they will be harvested (midterm). • Example – in fires t August 16, 2013 Why is Fert Lower Priority? 6 • +15m3/ha in 10 yrs • Cost is $450/ha Rehabilitation • Re-establish stands rendered uneconomic by MPB related mortality – with • + ~30m3/ha now? • +100m3/ha in 60 yrs • Cost is $1000-2000/ha Web Meeting Fertilization August 16, 2013 Fertilization vs Rehabilitation 7 Midterm: Yrs10-50 91% Pl in Yrs 1-5 Web Meeting Short term: 3.2 M Midterm: 1.8 M Long term: 3.6 M August 16, 2013 Base Case Review Lowest Point of Available Growing Stock is in Years 30-50. 8 Small but important role for IDF. Web Meeting Salvage in first two periods. August 16, 2013 Base Case Review Transition to managed stands starts in 20 yrs. Heavily reliant by 40 yrs. 9 Web Meeting Most >60% dead stands salvaged – leaving lesser impacted stands for Midterm August 16, 2013 Base Case Review Youngest stand profile (smallest timber) harvested between 30-50 yrs 10 Web Meeting August 16, 2013 Base Case Review • Average harvest volume in short term is 100m3/ha and then improves. • Average harvest age is ~90 years in the long term but gets a low as 68 in year 50. • Harvest area is very high during salvage period (30,000 ha/yr) but reaches a long term average of 15,000 ha/yr. 11 Web Meeting August 16, 2013 BASE CASE SENSITIVITIES Harvest Flows Min Harvest Volumes Shelf Life Min Harvest Ages 12 Web Meeting August 16, 2013 Alternative Base Case Harvest Flows • Alternative approaches to short term harvesting can yield different outcomes in the midterm. Avoiding the harvest of stands that remain viable in the midterm – improves the midterm but foregoes the economic value of the pine lost. 13 Web Meeting August 16, 2013 Sensitivity: Revised Min Harvest Criteria Always @80m³/ha • Short (+12%) • Mid (+21%) • Rise (+13%) • Long (+5%) Always @110m³/ha • Short (-4%) • Mid (-9%) • Rise (-1%) • Long (-6%) Base Case: 80 m³/ha for salvage, 110 m³/ha for second growth 14 Web Meeting August 16, 2013 Sensitivity: Revised Shelf-Life 15 Web Meeting August 16, 2013 Sensitivity: Revised Shelf-Life • • • • Short (+15%) Mid (~) Rise (+23%) Long (+5%) 16 Web Meeting August 16, 2013 Sensitivity: Longer MHAs (Quesnel Ex) 17 Web Meeting August 16, 2013 Sensitivity: Longer MHAs 18 Web Meeting • Currently very little utilization of deciduous material • Estimate opportunity • Deemed lower priority August 16, 2013 Sensitivity: Deciduous 19 Web Meeting • Harvesting small pine becomes less economic with longer haul distances • Deemed lower priority – not completed August 16, 2013 Sensitivity: Limit the Harvest of Small Pine 20 • Salvage effort and stand types salvaged • Shelf-life • Minimum harvest criteria (MHA) Web Meeting • WL TSA is heading towards a low in available volume after the 4th decade (29.3 MM m³) • Harvest forecasts are very sensitive to: August 16, 2013 Key Points: Base Case and Sensitivities 21 Web Meeting August 16, 2013 SILVICULTURE STRATEGIES 22 Area Treated Over Time Web Meeting Incremental volumes achieved after 10 yrs (single or multiple treatments) Pl @ 12m³/ha Fd @ 15m³/ha Sx @ 15m³/ha (Mulitple Sx fertilization done every 5 yrs, with larger gains) August 16, 2013 Strategy: Fertilization 23 Web Meeting August 16, 2013 Strategy: Fertilization • Budget maximized after 15 years • The model harvests all stands that are treated and does not treat stands that are not harvested. • Half of volume harvested in midterm is comes from natural stands. • Multiple Sx fertilization is prioritized (most cost efficient). 24 Web Meeting August 16, 2013 Strategy: Fertilization • • • • Short (~) Mid (0-10%) (little to no ACE effect occurs) Rise (+5%) Long (+8%) 25 Web Meeting • Relatively little area eligible (6,800 ha) • Lower priority than to fertilize existing stands with appropriate density – higher cost and gain is similar. • Low priority – dropped August 16, 2013 Strategy: PCT and Fertilize 26 Strategy: Spacing Dry-Belt Fd Web Meeting Area Treated August 16, 2013 (Thinning young thickets in NonUWR stands 10% volume increase at harvest $’s Spent 27 Web Meeting August 16, 2013 Strategy: Spacing Dry-Belt Fd • • • • Short (~) Mid (+3%) Rise (+1%) Long (not investigated) Delayed response as have to wait 30 yrs after treatment to harvest. 28 Strategy: Rehabilitation August 16, 2013 Reforest MPB impacted stands that are non-merch (<80m3/ha) Web Meeting Area Treated $’s Spent 29 Extensive opportunity, full budget spent (~1,500 ha/yr). Web Meeting August 16, 2013 Strategy: Rehabilitation • • • • Short (~) Mid (+8%) - volume at time of treatment + some THLB back in Rise (+13%) – Non merch stands brought back into production Long (+13%) – Non merch stands brought back into production 30 Strategy: Partial Cut in Constrained Areas Web Meeting Area Treated August 16, 2013 Harvest of 1/3 volume in constrained areas, no impact to non timber values $’s Spent 31 Web Meeting August 16, 2013 Strategy: Partial Cut in Constrained Areas • • • • Short (~) Mid (+14) Rise (no attempt to improve) Long (no attempt to improve) Significant improvement in midterm due to accessing stands that would otherwise not be available. 32 Strategy: Enhanced Basic Reforestation August 16, 2013 Improved well-spaced densities, fewer gaps (OAF1), more planting / class A seed Web Meeting Area Treated $’s Spent 33 Budget max reached in several periods, about 70% of stands logged in midterm get enhanced reforestation. Web Meeting August 16, 2013 Strategy: Enhanced Basic Reforestation • • • • Short (~) Mid (+5%) Rise (+2%) Long (+12%) First stands are ready in 35-45 years as min harvest volumes are reached sooner. Mid and long term benefit from enhanced yields. Little to no ACE effect. 34 Optimized Mix – $3 Million/yr Budget $’s Spent Web Meeting August 16, 2013 Area Treated • • • • • • Budget max reached every year Rehab and Enhanced Basic are dominant initially (first 5 yrs) Fertilization ramps up over time (almost all eligible stands treated before harvest) Majority of the budget spent on Rehab in all time periods Partial cutting is key to improving early midterm. Spacing of drybelt Fd is a focus in early periods. 35 Web Meeting August 16, 2013 Optimized Mix – $3 Million/yr Budget • • • • Short (~) Mid (+22%) Rise (+2%) Long (+11%) Midterm increased as priority over longterm. 36 Optimized Mix – $5 Million/yr Budget $’s Spent Web Meeting August 16, 2013 Area Treated • • Budget max reached every year (5 Million) Treatment decisions very similar to 3 million budget. • Heavy spending on rehab • Ramp up of fertilization • Steady spending on enhanced reforestation • Partial cutting to help the front end of the midterm. • Most thinning of Drybelt fir in early periods 37 Web Meeting August 16, 2013 Strategy: Composite Mix @ $5M/yr • • • • Short (~) Mid (+28%) Rise (+10%) Long (+17%) Midterm increased as priority over longterm. 38 Web Meeting August 16, 2013 ECONOMIC ASSESSMENT 39 Web Meeting • 2% discount rate • Net economic benefit of $25/m3 on the additional volume realized (net benefit to crown from additional cubic meter harvested and moving through the economy). August 16, 2013 Stand-Level Economics - Assumptions 40 Web Meeting August 16, 2013 Stand-Level Economics - Results Multi Spruce Fert (3-5) most attractive fert option. Rehab, Partial Cut, and Enhanced Basic have positive return at 2%. 41 Web Meeting $3M Budget NPV = $122 M $5M Budget NPV = $182 M August 16, 2013 Forest-Level Economics 42 Web Meeting August 16, 2013 Forest-Level Economics 43 Web Meeting • Rehab appears to be the largest opportunity and warrants significant investment. It buys wood in the short term from stands that will never be eligible, plus adds to the long term harvest by putting them into production. • Partial harvesting in constrained areas is the only strategy to help fill in the front of the midterm. It borrows volume from later in the forecast (i.e., no extra volume) • Fertilization is important but not as time sensitive as other treatments. There are several decades before any of these stands will be harvested so time exists to treat them. • Both Composite Scenarios (3M and 5M budgets) are similar in treatment selections/proportions and have positive NPV at the forest level (2% discount rate).
