Dracula under siege: Persistent demand for a threatened and range-restricted orchid taxa

Abstract: The sustainable use of biodiversity in international trade faces persistent challenges regarding source verification, taxonomic precision, and laundering detection. We analysed four decades of CITES data of Dracula orchids, a genus with 93% of species threatened by overexploitation, to quantify trade patterns, identify taxonomy-related reporting loopholes, and assess which traits predict trade intensity. Since 1981, 121 species (91% of all Dracula ) have been traded across 77-countries, with 49% exported from non-native countries and all species were recorded as artificially propagated. Ecuador and Colombia exported 78.7% of individuals with the USA and Germany comprising 62.4% imports. We found that 89% of all Dracula species were described from nursery specimens, primarily from non-native countries, and 18% entered trade within two years of scientific description, questioning establishing artificial stocks within short timeframes. Approximately 10% of trade involved genus-level reporting or invalid taxa, preventing accurate species verification. Widespread species and those native to Colombia and Ecuador dominated high-volume trade over long term, in contrast to range-restricted, hard-to-cultivate, and threatened species that appear less frequently in trade, whilst morphological traits showed no detectable effects on volume, frequency, and price. Our results indicate that listing the genus in CITES Appendix I may be necessary to prevent further erosion of evolutionary history. The centralised network structure presents a strategic intervention opportunity where targeted actions could transform Dracula conservation outcomes and establish replicable regulatory frameworks for other threatened taxon exhibiting similar concentrated trade networks.
