This report comprises a review of the biometric qualities of current non-timber forest product assessment methods comissioned under the ZF0077 pre-project of the Forest Research Programme of the United Kingdom Department for International Development.

The study undertook a review of anglophone literature concerned with non-timber forest product (NTFP) resource assessment. The intention was to examine the biometric quality of current methods and make recommendations for a programme of research to address any gaps. The focus of the research will be the provision of methods suitable for use in the tropics and sub-tropics but the literature review includes material from temperate and boreal forests. In all, 126 case studies were reviewed. Of these, 97 directly concerned the quantification of NTFP resource abundance, yield or growth. The papers were drawn from a wide range of disciplines and included work on exploited trees, herbs, fungi, fruit, mammals and birds.
