Criteria and indicators constitute an increasingly common policy tool to implement sustainable forest management (SFM) and to define clear priorities and targets. This should improve monitoring, reporting and assessment of key aspects of SFM performance. These guidelines provide specific concepts, definitions, tools and reference materials to guide the development process of national criteria and indicator sets for SFM. These guidelines have been developed to support the project Accountability Systems for Sustainable Forest Management in the Caucasus and Central Asia which is implemented through the UNECE and FAO Forestry and Timber Section and funded through the UN Development Account. The guidelines and the methods described within are used and applied for the development of national criteria and indicator sets for sustainable forest management in Armenia, Georgia, Kazakhstan, Kyrgyzstan and Uzbekistan. The guidelines might be also relevant for other countries
