Harvesting and operations

Program Manager: Mark Brown

Read our latest news in The Log.

The greatest cost component in the production of forest products by far is the cost of log harvesting and transport. As the rapidly expanding plantation estates come on line for harvesting, safety and productivity demands are driving high levels of sophisticated mechanisation in these processes, signifying an even greater level of capital investment. These financial considerations along the entire production chain mean that harvesting and log transport operations must be efficiently planned and implemented.

­RP3_Harvesting

The primary objective of the Harvesting and Operations Program is to significantly improve the safety and efficiency of industry partners' forest harvesting and log transport operations. The measure of efficiency will depend on the specific aspect of harvesting or transport operations under consideration; for example, operator safety, cost or revenue per cubic metre of production, per cent recovery and fuel consumption. The secondary objective of the program is to build capacity in forest harvesting and transport operations research in Australia.

The research program will study forest harvesting and log transport operations in a range of locations extending across southern Australia and in both native forest and plantations. The research work will be carried out by seven staff: a principal research fellow based at the University of Melbourne (Creswick campus, Victoria), two research fellows based at the University of Tasmania (Tasmania) and Murdoch University (Western Australia) and four part-time staff based in Melbourne or Creswick (Victoria), together with up to six postgraduate students. The program is strongly supported by at least 12 industry partners.

Research will be conducted under five subprojects:

  • safety, productivity and cost effectiveness of harvesting systems across sites / operations
  • safety, productivity, cost effectiveness and design of wood transport infrastructure
  • forest resource utilisation and waste reduction
  • bucking / scheduling optimisation
  • stand parameter information from harvest data

Ultimately, the research conducted will contribute to the development of safer and more efficient forest harvesting and log transport operations with increased levels of resource utilisation and value recovery from harvested areas. The development of a core group of internationally recognised Australian researchers will underpin ongoing improvements in these areas of interest well into the future.

Program Three (Harvesting and Operations) bulletins

Program Three ('Harvesting and operations') has recently released six bulletins:

  • Bulletin 1 outlines the results from a trial in which the impact of piece size and slope on the productivity and costs of cut-to-length harvesting equipment was investigated in a forest near Eden, New South Wales.
  • Bulletin 2 points out some inherent pitfalls in current harvester calibration procedures and outlines simple methods to improve calibration while also minimising costs and time required.
  • Bulletin 3 explores the impact of tare weight on transportation efficiency in Australian forest operations.
  • Bulletin 4 evaluates the productivity and cost of an in-field chipping operation.
  • Bulletin 5 presents the results of a harvesting trial which assessed the impact of stocking density, tree size and tree form on harvesting efficiency and cost.
  • Bulletin 6 compares harvester productivity in third-row versus fifth-row thinning of a Eucalyptus nitens plantation.

If you are a member of the CRC for Forestry, you can access the bulletins on the CRC for Forestry members' website. Otherwise, contact Program Manager Mark Brown to inquire about obtaining copies.

May 2008 workshop: machine evaluation on the front line
This half day workshop was designed to help frontline managers make the most of their valuable time when determining machine productivity and cost. One of the keys to ensuring that you are on the profitable side of that line is to know how to identify issues quickly, accurately assess them and act on the knowledge gained. This workshop was co-presented by a leading international visiting expert. The three workshops were held in May at Mount Gambier, SA; Albany, WA; and Campbell Town, Tas. [pdf 285.3 kb]
