BfN Schriften 504 - CITES Non-detriment Findings for Timber A nine-step process to support CITES Scientific Authorities making science-based non-detriment findings (NDFs) for timber / tree species listed in CITES Appendix II
Export permits for CITES Appendix II species, or parts or products derived from these, require that the Scientific Authority of the exporting country carries out a Non-Detriment Finding (NDF). NDFs are a procedure to scientifically evaluate parameters such as species distribution and habitats, population status and trends, harvest practices, as well as volumes and impact of trade in target species. They result in a recommendation to the CITES Management Authority of the exporting state. In general this recommendation is made as a positive NDF (necessary precondition for a CITES permit) or a negative NDF.
The structure, content and methods used to develop NDFs vary considerably. This is partly explained by the fact that there are different analytical requirements for different groups of species. In addition, there is an absence of specific guidance documents on how to develop CITES NDFs for specific taxa. In the case of timber/tree species only principle guidance documents and case studies have been developed until now. These resulted from discus-sions on and efforts to develop specific guidance for making an NDF for timber in CITES for over a number of years.
