Operational gain: Measuring the capture of genetic gain

Abstract

The southern African forestry and forest products industry contributes two percent of the countries gross domestic product, yet is one ofthe most globalised industrial sectors. Forest product exports make up eight percent of the countries total exports and produce an annual net trade surplus of R5 billion. To remain globally competitive, the southernMrican forestry industry must continue to produce low cost wood of the required quality for processors. Increasing yield per hectare is a significant means to achieving this aim and is actively pursued by industry players, particularly through genetic improvement of planting stock.
