1 NEW USES FOR OLD DATA Green Triangle Permanent Growth Plot Projects Dr Jim O Hehir General Manager Planning and Development And many others

2 Green Triangle SE South Australia and SW Victoria South Australia Victoria

3 Green Triangle - Extent, Producivity and Industry GT Plantation Industry: 170,000 ha each of pine (Pinus radiata) and blue gum (Eucalyptus globulus). Pine local integrated & export markets Eucalypt export pulp/chip markets. Growth Rates: Pine average m3/ha/yr; rotation lengths years; multi thinned. Eucalypt average m3/ha/yr rotation lengths years; single clearfelling operation. 3

4 South Australia - Informaion needs 1870s Geographic extent, species and site suitability Species & provenance selection Survival and growth rate 1900s Radiata pine preferred species Beginning wide scale planting 1930s Royal commission Radiata pine for structural timber Plantation forestry industrialisation Silvicultural development Initial stocking Thinning Site treatments Growth & yield biometrics to predict log availability NW Jolly PSP s

5 South Australian - PSP v Inventory PSP Permanent growth plots Growth & research trials model building Long term across rotations Expensive per plot - few High precision measurement, few assumptions Inventory plots Represent resource what s there now Temporal Cheap per plot - many Indirect & few measurement points, assumptions Lower precision measurement acceptable Sacred sites Strong IP at individual plot level Normal treatment Strong IP at collective plot level

6 South Australian PSPs Since 1935 ~600 ~ 0.1ha radiata, globulus, pinaster, muricata Normal operations excluded Dbh, Ht, direct tree volume measurement for whole rotation Documented measurement standards; known changes Continuity of trained measurement Known geographic, climatic and temporal extent Multiple rotations same location 40+ years of unimproved genetics Silvicultural gradients Paper/computerised systems; Electronic Large amount of paper only data including tree measurements staff 6

11 GT growers collaboraive projects ABP, FSA, GTFP, HVP, OFO, TPPL Forestry Systems, Silmetra, Dr Richard Woollons Project 1 - Data status paper/electronic & secure Project 2 - Target priority data for entry Project 3 Modelling Next stages New measurements and plot establishment Collaboraion needs & structures Governance & intellectual property & ownership Opions for alternaive recording & management system New data types e.g. LiDAR Links to other datasets e.g. geneic

12 Project 2 - Data entry Criteria for tree volume measurement data entry from paper: Priority 1 plots with good measurement history & already parially entered in the ForestrySA PMS. Priority 2 plots with good measurement history but no data in the PMS. Priority 3 - everything else. Achieved: 225 Priority 1 & 2 plots entered as at 31 March 2017, project conclusion. 3 metre secionally measured trees entered: 40,006; comprising 32,515 Imperial & 7,491 Metric Regional Volume Table trees: 22,932; comprising 9,865 Imperial & 13,067 Metric 12

14 Project 3 Modelling Increase YTGen funcionality for GT using addiional PSP data: 1. Stand-level growth model for Pinus radiata in the Green Triangle - Predicing changes in predominant height, basal area & survival over ime - Brian Rawley; Richard Woollons January Allocaion models from stand to tree - funcions for predicing changes in survival, diameter & height of individual trees over ime, for use in Pinus radiata growth models in the GT - Brian Rawley June Revision of tree taper model - Hiquan Bi 4. Modiicaion of feriliser & thinning model - Brian Rawley/Jim O Hehir 1 & 2 complete; 3 underway & 4 seeking a quote. Feasibility of implemening full SA biometrics in YTGEN? Beneits depend on collaborator taking commercial advantage of improved log availability predicions when biometric models deployed in planning systems. At least two signiicant beneits: Forest values improved with greater conidence in product predicions & biometrics used to generate them. Beter allocaion of resources based on beter products predicions. 14
