Articles III and IV of the CITES Convention state that Parties shall only export Appendix II listed species when they are satisfied that such export will not be detrimental to the survival of that species. A key aspect of this process is the creation of non-detriment findings (NDFs), which are science-based assessments that consider whether trade levels of CITES-listed species are likely to be sustainable. There is no “one size fits all” approach to NDFs, and different taxa present varying challenges for conducting these assessments. Undertaking NDFs in data poor environments can be challenging, particularly in situations where population trends are not well known, where species have complex life histories, or where species are highly migratory and move through areas under the jurisdiction of multiples Parties. This report contains in-depth reviews of the biology, conservation status and management of three taxa that were identified by CITES Parties in Central America and the Caribbean as priority species where more information was required to produce robust non-detriment findings – Honduras rosewood (Dalbergia stevensonii), queen conch (Stombus gigas) and hammerhead sharks (Sphyrna spp.).
