This paper reviews various methodologies for forest valuation and describes how they have been used in the preparation of forestry investment projects and programmes. It confirms that many potentially good valuation methodologies exist and it presents summaries of most of the main methodologies used. The document highlights other important considerations that have to be considered in any analysis (e.g. distribution of costs and benefits, different perceptions of value). It also reveals that valuation is not widely used at the moment in forestry project preparation.
