Ongoing 132 Due date Region FA section Milestone Progress Within next five years UNE, LNE 3.5 Att. 8 Refinement of resource availability by improving the inventory such as additional plot measurements (funding provided at $500 000 pa for five years). In progress Forests NSW has implemented a Forest Inventory Policy, which is designed to account for harvesting activity and maintain the currency of its strategic resource data. Continuous replacement of FRAMES plots is part of this policy. Improvements to FRAMES Tools In relation to FRAMES improvements, by the end of 2006, Forests NSW had completed a broad series of improvements to its FRAMES modelling, including: Biometrics • Growth models have been updated for all areas using recent Permanent Growth Plot (PGP) measure data. • Models have also been simplified to improve rigorousness with respect to implementation and testing. • Further data were collected and analysed to improve the recovery factors, volume functions, taper functions, height/diameter functions and tree product apportionment equations biometrics. Growth and yield simulation • FRAMES has been adapted to report species level yield trends. • Changes have been made to the modelled product mix to provide more realistic and flexible product categories. • The simulation tool has been integrated with the inventory and Woodstock wood flow model systems to improve efficiency and user-friendliness. • New reports have been developed that include the profiles of average pre- and post-harvest stand states for areas that meet the harvest criteria. This report can be used by regional staff to ground-truth the modelled harvest specifications. • Silvicultural and harvesting assumptions have been updated as a result of silviculture studies in the North Coast region. • New log level trace reports have also been incorporated into the growth and yield simulation process, enabling precise log level data to be incorporated into FRAMES yield tables. Previous yield simulation models accurately predicted standing yield at estate level but were found to vary significantly at more localised levels. The new log trace approach enables precise estimates at local levels. Area management Because of the complex nature of net area management and the large number of spatial inputs to area modelling, Forests NSW has restructured its strategic net area management toolkit. This has resulted in the development of a grid-based area prediction tool for North Coast regions. The new modelling environment permits layers that contribute to area availability to be easily extracted and updated as new data becomes available. Estate models • Changes have been made from Spectrum RFA to the Woodstock estate modelling system to facilitate more reliable and efficient yield scheduling and reporting at a range of spatial levels. • Resource growth and yield estimates have been defined at a more localised level (e.g. in contractor management zones) to support planning and monitoring activities. • The model has been modified to ensure that only appropriate silvicultural intensities are applied to defined management areas. Forests NSW will continue to review the utility of these and other tools for informing future management decisions. As part of remeasurement, PGPs have been converted to a new plot size (0.2 ha). All new PGPs will be established at the new plot size. The larger plot size will result in a better capture of variability and improve mortality and recruitment modelling. When data become available, the current models will be reviewed and if necessary updated and incorporated in FRAMES. NSW FOREST AGREEMENTS AND INTEGRATED FORESTRY OPERATIONS APPROVALS
Due date Region FA section Milestone Progress Ongoing Eden 2007 30 April Sthn 3.5 Att. 8 3.5 Att. 6(6e) Refinement of resource availability by improving the inventory, such as additional plot measurements. 25 STANDSIM was used as the scheduling tool in the Eden RFA. Refinement of resource availability on native forests by additional inventory plot measurements to improve volume estimates at a regional level. In progress Intensive inventory activities in regrowth forests in Eden continue. This inventory activity has resulted in improved site quality classification, at the regional level. Additionally, within the PGP inventory program three existing plots were remeasured in 2005. Another two existing plots are proposed to be remeasured in late 2006. As part of remeasurement, PGPs have been converted to a new plot size. The larger plot size will result in a better capture of variability and improve mortality and recruitment modelling. Eden-specific tools were reported in the 2006–2007 FA report. In 2002–2003, Forests NSW designed and implemented an inventory-plot management system, called REDEN, for modelling the Eden even-aged regrowth resource. The system is designed to predict individual tree and stand growth and yield for the even-aged regrowth forests and includes biometrics specific to the regrowth forests of the south-east of the State. The yield tables generated by REDEN are designed to be used by yield-scheduling tools for estate-level modelling. The drivers of the models in REDEN are stand age, measurement of site quality (site height), and the number of mature trees. Local taper and volume functions have also been developed; they allow the input of product specifications and determination of theoretical product (pulp) volumes by size. The outputs of the REDEN system are yield tables for the regrowth forest that predict the piece size and volume available for harvest. These results are then combined with net harvestable area estimates and used to schedule thinning operations by using Spatial Woodstock in much the same way as FRAMES. Because of the organisational shift from Spectrum and StandSim 25 to Woodstock for yield-scheduling analysis, the outputs from REDEN are formatted so they can be incorporated into the Woodstock package. The initial analysis from REDEN and Woodstock focused on short-term timber availability issues, notably the current 20-year planning horizon. After the preliminary results were refined and evaluated, the system was then expanded to incorporate longer-term modelling of the resource, bringing it in line with other FRAMES models to consider a full 200-year strategic planning horizon. This work is still in progress, the current focus is on sensitivity analysis of the outputs. After REDEN was developed, the MARVL inventory system, licensed to Forests NSW by New Zealand Forest Research, was upgraded and given the new name Atlas Cruiser. Although Forests NSW has converted the inventory data from the MARVL format for North and South Coasts, the complex nature of the Cruiser data model, the long modelling horizons and the nature of the inventory formats used for the Eden regrowth resource have delayed using this data for EDEN. Forests NSW will continue to review the utility of these and other tools for informing future management decisions. In progress Some planning for additional inventory plots began in the Tumut sub-region, but actual establishment of new inventory plots in areas harvested around Batemans Bay was completed in late 2006. Forty-one new plots were established. A FRAMES strategic inventory plot update program has been completed in accordance with Forests NSW Forest Inventory Policy. Additional plots have been measured to provide an even intensity (1 plot in 200 ha) of plots across the estate. NSW FOREST AGREEMENTS AND INTEGRATED FORESTRY OPERATIONS APPROVALS 133
