This does not contradict our findings of the vast diversity of traded species, nor that many species have recently been (e.g. argue that trade does not necessarily equate to enhanced extinction risk, and that sustainable trade can improve the conservation of traded species and mitigate other threats. Our study uses a rigorously assembled database to make a global assessment of traded species-both legal and illegal, and from national to international scales-and to identify the global hotspots of trade diversity.įirst, Challender et al. raise three areas of concern about our study.
