This paper describes and analyses a sample of value chains of timber sourced from farms in the Mount Kenya area. A combination of research methods were used including focus group discussions, a timber busi ness census, and an in - depth business questionnaire applied to a stratified random sample of timber businesses and their value chains. The research methodology and value chain survey tool are based on the methodology of “filiere” analysis. The business questionnaire includes the institutional dimension (the identification of direct and indirect actors), the technical dimension, (conversion rates and efficiency), and the economic dimension (value added at each stage of the chain). Eight distinct processing s tages (possible actions) were identified in the various value chains described by the survey from the farm to the end user. Value chains varied as to how they combined or amalgamated the eight different stages along the length of the chain.Adequate data enable a detailed analysis of 17 of those chains working with Grevillea robusta. The results of the various research components are presented and comparisons are made between the form and structure of the chains . The role of ownership or hiring of different stages of the chain is discussed. Recommendations to raise farmer s’ returns and enhance value chain efficiency are made. The technical dimension of the farm timber value chains, conversion rates and efficiency are key elements in overall returns and value added. As a result of this research the World Agroforestry Centre has initiated training activities which address skills upgrading in the handling and processing of farm -produced timber. Future possible scenarios of market-oriented farm timber production and conditions required for their viability are presented
