While national and/or regional research institutions generally provide basic technological input and operational recommendations for forestry, these frequently require adaptation to local site and infrastructural conditions. In addition, many plantations experience relatively unique problems and challenges, and thus small scale local research programmes are required for line management (e.g. seedling type/standard, fertilizing, weed control and harvesting system). Such in-house programmes can be more efficiently undertaken following the stratification of land holdings into site types per field of investigation. A similar research strategy applies to site-species/genotype matching and their combined influences on fibre properties, and the identification of major sites for which species/genotypes are poorly adapted.
