EXECUTIVE SUMMARY The Government (MAF) has requested estimates of carbon stocks by stand age for various tree species and tending regimes in nine growth model regions. These carbon stock tables are intended to be used for the calculation of carbon emissions through deforestation. This report provides the requested carbon stock tables and describes how they were constructed. In each case, the most applicable growth model was selected to construct a stem volume yield tables for various species and regimes, e.g. 300Index for radiata pine and 500Index for Douglas-fir. The modelled regimes were supplied by MAF and the resulting volume yield tables were converted to carbon stocks using the carbon model, C_Change. The modelled stem volume yield tables were compared with the 1995 NEFD yield tables and on request by MAF a scaling factor of 0.717 was applied to the modelled yield tables and to the resulting carbon stocks. The reported tables do not purport to represent actual carbon stored in any one specific stand, nor the expected mean values for any geographical region.

DEFORESTATION CARBON STOCK TABLES INTRODUCTION The Government has agreed in principle that owners of pre-1990 planted forest will be subject (with certain exemptions) to the Climate Change Response (Emissions Trading) Amendment Act. Owners who decide to deforest (i.e. convert to another land use) after 1 January 2008 will be liable for the carbon emitted as a result of deforestation. The core obligations of those deforesting pre-1990 forest lands will be to

- report annually to the administering agency about any area deforested; - calculate, using a specified methodology, the emissions associated with this

deforestation; - surrender a number of New Zealand units (NZUs) or other acceptable units equal

to the calculated emissions. The specified methodology for calculating deforestation emissions will use a series of carbon yield tables that will be included in the Regulations to the Climate Change Response (Emissions trading) Amendment Act. This report presents tables of forest biomass carbon1 and describes the construction methods used in their development. The tables do not purport to represent actual carbon stored in any one specific stand, nor the expected mean values for any geographical region.

1 Throughout the report the term “carbon” is used to mean actual carbon in tonnes per hectare. To convert numeric values of carbon to carbon dioxide equivalent, multiply by 44/12.

METHODS Species and stand tending regimes MAF requested estimates of forest carbon stocks by stand age class for various tree species and stand tending regimes, for each geographical (growth modelling) region in New Zealand. The site productivity levels to be used were provided by MAF, based on specified values of 300Index and/or Site Index. The species and regimes modelled are shown in Table 1.

Index300 and Site Index used MAF supplied 300Index and Site Index values to be used for radiata pine in each of the nine Growth Modelling Regions for predicting stem total volume inside bark yields and

7

stand carbon stocks by stand age class. These index values were originally calculated using plot data from a series of replicated genetic gain trials provided by the Stand Growth Modelling Research cooperative and are tabulated in the Radiata Pine Calculator (MacLaren and Knowles 2005). As these index values were calculated using an earlier version of the 300 Index Growth Model, they were recalculated for the same Permanent Sample Plot (PSP) data using the most recent version of the 300 Index Model (Version 2.1) and national volume function. The values represent GF from 0 to 25. Table 2: Radiata pine 300Index and Site Index values for Growth Modelling Regions.

Models used Volume and carbon yield tables were developed using a combination of various stem volume growth models and the biomass partitioning model C_Change (Beets et al. 1999). The 300 Index Growth model (Kimberley et al. 2005) was used for radiata pine, using a new national volume equation (Kimberley and Beets 2007), in combination with C_Change. For Douglas-fir, the 500 Index Growth model (Knowles 2005) as implemented in the Douglas-fir Calculator (MacLaren and Knowles 2005), was used in combination with C_change.

8

For Hardwoods the Eucalyptus nitens Growth model (Candy 2002) was used in combination with C_change. Other Softwoods carbon yield tables were assumed to be 50% of the area-weighted average carbon stocks obtained for the two radiata pine regimes already described. A reduction of 50% is used in the 1995 NEFD Yield table for other softwoods. Wood densities The mean outer wood density of radiata pine for each of the nine regions are based on the former NZ Forest Service Conservancies which overlap or contain more than one of the nine growth model regions (Table 3) as tabulated in Cown et al. 1991. The outerwood density of rings 21-25 was input into a wood density model for predicting the density of annual growth sheaths (Beets and Kimberley 2007). Table 3: Basic density for ring group 21-25 years. Density figures are taken from Cown et al 1991, based on NZ Forest Service conservancies.

Wood density for Douglas fir was taken from the Douglas fir Calculator. Density was input by stand age class into the C_Change model. The wood density of other softwoods was assumed to be the same as radiata pine in the same growth modelling region. Wood density of hardwoods is based on Shelbourne et al 2002 representing density of Eucalyptus nitens as one of the more common eucalypt species likely to be deforested in New Zealand. Densities from a number of sites over New Zealand, were averaged to calculate a national density for Eucalyptus nitens. The effect of ring age on wood density variation from pith to bark were based on published studies (McKinley et al 2000).

Altitude and Latitude for modelling a regional radiata pine yield table Altitude and latitude influence height growth and are used as additional input variables in the 300Index model. For each of the nine Growth Modelling Regions the geographical centre point was determined and this latitude was used as model input. The mean altitude for each Growth Modelling Region was obtained by averaging altitudes of forests in the region. The occurrence and distribution of exotic forests for the calculation of mean altitude were based on the Forest owner database Version 2004 (MAF website). Age of pruning and thinning for radiata pine and Douglas-fir For radiata pine the stand age when a specified pruning lift was undertaken varied by region, depending on the Site Index and 300Index (and to a lesser extent on altitude and latitude). The Radiata Pine Calculator was used to schedule pruning operations (stand age was rounded to nearest integer) to ensure that crown length averaged 4 m following each lift. Radiata pine stands were scheduled for thinning when the stand was predicted to attain a specified Mean Top Height (MTH) using the Radiata Pine Calculator. For example, a target MTH of 12 m was specified for the radiata minimum tending regime (unpruned). Thinning of Douglas-fir stands was scheduled using the Douglas-fir Calculator based on a MTH of 16 metres. Further specifications for Douglas fir and other species The Douglas-fir Calculator was used to develop a single national volume yield table for stands at least 7 years of age and older. In stands less than 7 years of age stem volumes were estimated using the following formulae based on Kimberley and Beets (2007)

The national yield table for Douglas-fir was based on: • a Site Index of 31.3 m

10

• a 500 Index of 18.4 m3/ha/year • a latitude of 40 degrees

The Index500 and Site Index values are the default values in the Douglas-fir Calculator and were derived using all available PSP data for Douglas-fir in New Zealand. The same database was used to develop the 500 Index Growth Model (the growth model incorporated in the Douglas-fir Calculator). The Eucalyptus nitens growth model was used to develop a national stem volume table for hardwoods. This model was developed using all available PSP data for Eucalyptus nitens in both New Zealand and Tasmania (Candy 2002). The national volume table assumed a site index of 28.6, a mean tree height (MH) of 13.3 m and a BA of 25.6 m2/ha at stand age 11 years. For Other Softwoods, a national radiata pine volume table was developed from the area weighted average of the regional yield tables, and then reduced by 50%, to be consistent with the reduction of 50% that was used in the 1995 NEFD Yield table for other softwoods. Areas of forests within each region were taken from the NEFD 2006 and are shown in Table 4. Table 4: Growth modelling region and area of exotic forests.

NEFD tables for comparison The yield tables developed using the growth models were compared with the version of the NEFD yield tables supplied by MAF (Table 5). Graphs showing the modelled and

NEFD yield curves by regime, grouped by Growth Modelling Region, are shown in an Appendix to this report. Table 5: NEFD yield tables supplied by MAF

Scaling factor A scaling factor was applied to adjust the modelled volume yield tables to the NEFD 1995 yield tables as requested by MAF. A fixed scaling factor was derived from the existing NEFD information on the average clearfell yield for radiata pine, based on the 2006 NEFD report. The average recovered volume at 1st April 2006 was 486 m3/ha at age 28.2 years. Assuming a mean recovery of 85%, his results in 486/0.85 = 572 m3/ha of total stem volume. The comparison of this total stem volume at age 28 (572 m3/ha) with the modelled weighted average volume of 781 m3/ha (are weighted by area for pruned and unpruned regimes in each regions) gives a scaling factor of 26.8% (or 0.732). This factor was used to scale the modelled volume yield tables for radiata pine. The same factor was applied to Douglas-fir, other softwoods and hardwoods - because insufficient data exists from the NEFD regarding species other than radiata pine. Thinning events and their representation in the Yield tables Thinning affects the carbon allocation significantly, especially in the year that thinning takes place. This is evident through a reduction in tree volume and live carbon stocks in that year although the growth of the remaining trees ensures that carbon stocks recover quickly in subsequent years. Because the thinned trees are transferred to the dead biomass pools at time of thinning, the reduction in total carbon stocks is much less pronounced than the reduction in live carbon. It should be noted that C_Change predicts a slight reduction in total carbon at the point of thinning because fine roots associated with the thinned trees are allocated immediately to the soil carbon pool. Soil

carbon is not included in these yield tables (Beets pers. comm.). To avoid the occurrence of this short term drop in carbon stocks we interpolated the yield table data before the thinning event and the following year. This results in a smoothing of the yield curve. In the case of a very heavy thinning with a relatively slow growing tree species (e.g. Douglas-fir) or even in some cases with radiata pine, there can be a real drop in the stand total carbon in subsequent years. This occurs whenever the loss in carbon due to the decay of the large pool of dead material (from thinnings) exceeds the ability of the residual trees to sequester carbon. The decay rates for dead biomass of all tree species used in these tables are based on radiata pine. The specified heavy thinning regimes used in this report caused a marked slow down in carbon sequestration, and in some cases, a temporary loss in total carbon. This occurred because the modelled yield tables were chosen to be representative of actual regimes. This reduction in carbon sequestration rate, although reflecting the nominated regime, could lead to inconsistent results when applying the tables for deforestation purposes. To avoid such short term thinning effects, the specified stocking reduction following thinning was spread out over three years so that the ‘average’ stocking across a large number of stands is modelled rather than the actual stocking of any single stand. The resulting yield table will therefore not representative any individual stand, but should more accurately reflect the average volume and carbon stocks across a large number of stands. Second rotation stands Young second rotation stands show higher carbon stocks then first rotation stands (afforestation), because dead woody litter and fine woody litter residues are carried over from the previous rotation. Residues from the previous rotation were modelled assuming the same thinning and pruning regimes were applied in both rotations, and assuming first rotation stands were clearfelled at ages given in Table 6: Table 6: Rotation age of first rotation stands used for modelling carbon stocks in 2nd Rotation stands

Extraction of 85% of the stem volume following clearfelling was assumed. Averaging Carbon stocks of radiata regimes for regions MAF requested the averaging of the modelled radiata regimes for each region. The resulting “average” carbon stocks were then scaled as described above. We averaged the modelled carbon stocks based on the pruned and unpruned radiata regimes for each region to derive “average” carbon stocks by using an area weighted averaging to account for differences in area of unpruned and pruned regimes in the modelled regions. The areas by regime (unpruned /pruned) were taken from the NEFD 2006 for the nine modelled regions and are shown in Table 7.

Figure 3. Volume yield table graph for Douglas fir, hardwoods and other softwoods (unscaled).

The volume yield tables for all species, growth model regions and regimes are compared graphically with NEFD yield tables in the Appendix. Modelled Carbon yield tables Carbon yield tables for aboveground live biomass, below ground biomass, dead wood litter (coarse woody debris), and fine litter were calculated from the stem volume yield tables using C_Change, and are shown in the Appendix. Total carbon in these four pools (which excludes mineral soil carbon) is also shown along with carbon dioxide equivalent, calculated by multiplying total carbon by 44/12. The carbon yield tables for radiata pine and other softwoods start from age 9 and end at age 50. Carbon yield tables for Douglas-fir start from age 9 and end at age 80 and for hardwoods at age 9 and end at age 25. MAF stated that for stands were trees are harvested at age 8 or younger, the deforestation emission is calculated as if the trees were at the age of those last harvested from the land. As an example, predicted carbon pools for Bay of Plenty unpruned radiata pine are shown in Figure 4. Aboveground and below ground biomass carbon both generally increase with stand age. However when stands are thinned a decrease in these live

16

pools occurs, because a portion of live tree biomass is relocated into the dead wood litter and fine litter pools.

Representation of thinnings in the yield table The nominated thinning regimes were spread over 3 years to better represent stocking reductions expected across a large number of stands. The effect of spreading thinning events across 3 years instead of thinning in one year on the stand total carbon stocks is shown in Figure 5. Spreading thinning events over time considerably reduces the ephemeral drop in carbon stocks that is evident when thinning occurs all in one year (Figure 5).

Comparison between PSP data and modelled yield To test the representativeness of the modelled yield tables and to check for possible anomalies, the modelled yield curves were compared with estimates based on a nationwide database of permanent sample plots (PSPs). Plots were selected to represent regimes similar to the two radiata pine regimes used in this report. A smoothing spline function was used to estimate the mean volume yield curve of the PSP data and this was superimposed on the predicted growth curves for Gisborne/East Cape and Canterbury regions which represented the highest and lowest productivity regions according to the modelled yield tables. Figures 6 and 7 show the PSP data, the mean spline curve fitted to the PSP data, and the modelled yield curves for respectively the unpruned and pruned radiata pine regimes. Except for the period before the heavy thinning event the two regional yield curves modelled for the unpruned radiata pine regime, lie above and below the mean yield from the PSP data. For this regime, PSPs were selected from the database on the basis of stocking at age 20 (PSPs with 350 to 450 sph at age 20 were selected). The differences between the PSP data and model at young ages can be explained by the thinning regime (most PSPs were thinned earlier than the specified regime – see Figure 8). Also,

18

it is possible that unpruned higher-stocked stands such as those represented by this regime tend to be found on poorer sites. This may explain why the mean PSP yield for this regime tends to be slightly closer to the yield table for the poorer productivity region than to that for Gisborne, especially at older stand ages. In addition PSP data at older ages represent unimproved stands (low level of genetic improvement and site preparation), which can be expected to reduce volume yield of PSP plots at older ages compared to modelled yields. The modelled yield curves for the pruned radiata pine regime are in agreement with the PSP data, with a similar stocking (PSPs were selected with between 200 to 300 sph at age 20, and with pruned height greater then 3m). The mean of the PSP data lies between the two modelled yield curves which represent the upper and lower bounds of regional productivity levels. Overall, the comparison between nationwide PSP data and the modelled regional radiata pine yield tables revealed no major deficiencies or abnormal behaviour.

Comparison of modelled Yield Tables with NEFD Yield tables The modelled stem volume tables were also compared with the total stem volumes of the relevant NEFD tables. Overall the NEFD yield tables showed lower volumes than the modelled yield tables (Figures 9 & 10; further graphs are in the Appendix).

20

In some Growth Modelling Regions e.g. Hawkes Bay, Gisborne, Waikato-Taupo the differences between our modelled tables and the NEFD tables were small. The South Island growth modelling regions showed greater differences, with Nelson Marlborough showing the smallest difference and Canterbury the greatest difference especially at older stand ages. The differences between the modelled yield tables and NEFD yield tables result from differences in the underlying data used for deriving the tables. For example, NEFD tables are based on areas that are not fully stocked in contrast to the generally fully-stocked PSPs that were used to estimate regional 300 Index values (radiata pine) and 500 Index values (Douglas-fir). To overcome this difference, either the modelled yield tables could be adjusted to account for stocking difference (e.g. reduced by 20%), or alternatively unstocked areas (roads, patches of scrub etc.) could be excluded when determining the deforestation areas.

Ave Scaled Yield

Figure 10. Modelled Volume for Growth Modelling Region Canterbury/West Coast compared with NEFD yield table data. Scaled average yield for the modelled radiata regimes (not area weighted) is also shown.

Another difference between NEFD and modelled tables is that, while the 300 Index (or 500 Index) represents an average productivity level for relatively recently planted stands, the NEFD table represents “snapshots” in time for each year in the current resource, and therefore is a mix between younger stands with improved stocks and silvicultural management and older stands established with less improved stock and variable management practices. Another discrepancy might exist between the site productivity indices used for model predictions (300 Index and 500 Index) and actual site productivity of the stands used in developing the NEFD tables. The regional 300 Index values used in this study came from lookup tables provided in the Radiata Pine Calculator which were derived from mean estimates of PSPs provided by the Stand Growth Modelling Cooperative. However, the distribution of these PSPs in each region may not necessarily be completely representative of the forests in that region. Rather than relying on 300 Indices calculated from PSP data, an alternative approach would be to derive them from the NEFD yield tables (e.g., using the NEFD volume at age 20 years). This would give volume predictions that were in line with NEFD yields.

22

Scaled modelled Yield compared to NEFD1995 yield The comparison of the scaled modelled yield with the 1995 NEFD yield tables shows that the scaling results in a conservative modelled yield for most of the regions, e.g. Waikato /Taupo (see Figure 9 & 10 and also Appendix). For Hardwoods the scaling resulted in a still very high modelled yield compared to the 1995 NEFD yield. CONCLUSIONS Users of these yield tables should be aware that they represent average specified productivity and stocking values for reasonably large regions. Site productivity and silvicultural regimes, and hence Carbon stocks for specific stands within those regions may vary significantly from the yield tables produced for this report. The yield tables presented in the Appendix have not been adjusted by experience factors. As such they represent ideal conditions, in both net stocked area and implementation of silvicultural prescriptions. For the reasons listed above the tables do not purport to provide an accurate estimate of carbon stock for any specific forest, REFERENCES Beets PN, Kimberley MO, McKinley RB 2007.
