Private Forests Tasmania - Strategic Forest Modelling
Development of a strategic forest resource model and integrated optimiser model.
Designed, programmed and implemented a comprehensive GIS model of 20 year wood fibre availability sourced from the 768 000ha private ‘non-industrial’ Tasmanian native and plantation forest resource. The Strategic Forest GIS Model, and accompanying Optimiser model and report, was prepared on behalf of Private Forests Tasmania to support a study into the feasibility and optimal location of wood processing plants within Tasmania. The report is published under the title ‘Private Forest Resource 2012: Where are the best locations for a hypothetical Tasmanian wood processing plant?’.
- Spatially modelled the Non-Industrial Private Forest (NIPF) estate as at 31st December 2011 using data from a variety of sources including:
- Forest Practices Plan harvesting & regeneration records from 1997 to 2011;
- Tasmanian Reserve Estate;
- Private Forest Timber Reserves;
- Volume discounts to compensate for yield reconciliation analysis, and;
- Area discounts to compensate for environmental, legal and landowner restrictions on harvesting.
- Developed a 20 year growth & harvesting simulation model based on sustainable harvesting & regeneration practices as appropriate to the ecological requirements of each forest type.
- ArcGIS 10 Add-In Optimiser Model that determined optimum locations for a hypothetical processing plant, based on minimising wood catchment area, using a 5km grid across Tasmania:
- Spatial distribution of NIPF harvestable volume:
- Visual representations of optimal sites for wood processing plants across Tasmania:
- Comprehensive report outlining modelling inputs, methodology, assumptions, outputs & limitations.
