During 1997, the need for a South African Cable Yarding Safety and Operating Handbook was identified as being important to the South African Forestry Industry, to help improve the safety and efficiency of local cable yarding operations. A great deal of literature was available at the time from many international sources but no single document satisfied South African specific needs. South Africa has a unique combination of terrain conditions, road spacing, tree sizes, cable yarder sizes and configurations amongst other variables.
This South African Standard for Time-studies will provide a common and standard time-study methodology for the South African Forest Industry; a protocol that does not currently exist. Its implementation will serve the purpose of aligning the South African Forest Industry with international forest operations development and assist with the "modernisation" of the Industry’s forest operations.
The first edition of this document was known as the Harvesting Code of Practice and resulted from a project initiated by Forest Engineering Southern Africa (FESA) in 1992. In the second edition of the document, it was renamed the Guidelines for Forest Engineering Practices in South Africa, and was published in 1999.
Timber harvesting offers many challenges to practitioners, harvesting planners and harvesting managers. Among these challenges is the selection and optimal application of harvesting equipment and systems for ground based harvesting operations. Ground based equipment and systems can operate successfully under a wide range of conditions, and the conditions suitable to each system can overlap considerably.
The objective of this handbook is to compile all of the information needed to effectively plan and carry out forest road construction and maintenance operations in one location. Many handbooks exist on forest road construction and maintenance, but none have been written for the South African forest industry. A wide-ranging group of experts was brought together to determine the content and layout of this publication. Forest roads provide required access for management of forest resources.
The research conducted at the Wattle Research Institute / Institute for Commercial Forestry Research and by other individuals and organisations over the past fifty years has played an important role in transforming a species introduced into South Africa as a tree to be used for shade for livestock, shelterbelts, windbreaks and for fuelwood, into a major plantation species that contributes substantially to the South African Forestry and Forest Products sector.
