Determining the sustainability of legal wildlife trade.

Exploitation of wildlife represents one of the greatest threats to species survival according to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. Whilst detrimental impacts of illegal trade are well recognised, legal trade is often equated to being sustainable despite the lack of evidence or data in the majority of cases. We review the sustainability of wildlife trade, the adequacy of tools, safeguards, and frameworks to understand and regulate trade, and identify gaps in data that undermine our ability to truly understand the sustainability of trade. We provide 183 examples showing unsustainable trade in a broad range of taxonomic groups. In most cases, neither illegal nor legal trade are supported by rigorous evidence of sustainability, with the lack of data on export levels and population monitoring data precluding true assessments of species or population-level impacts. We propose a more precautionary approach to wildlife trade and monitoring that requires those who profit from trade to provide proof of sustainability. We then identify four core areas that must be strengthened to achieve this goal: (1) rigorous data collection and analyses of populations; (2) linking trade quotas to IUCN and international accords; (3) improved databases and compliance of trade; and (4) enhanced understanding of trade bans, market forces, and species substitutions. Enacting these core areas in regulatory frameworks, including CITES, is essential to the continued survival of many threatened species. There are no winners from unsustainable collection and trade: without sustainable management not only will species or populations become extinct, but communities dependent upon these species will lose livelihoods.

The Rush for the Rare: Reptiles and Amphibians in the European Pet Trade.

Direct exploitation is one of the five main reasons for the loss of biodiversity, and collections for the international pet trade are an ongoing threat for many reptiles and amphibians. The European Union and in particular Germany have a central role as a hub and destination for exotic pets from all over the world. Rare species of reptiles and amphibians especially are in the focus of collectors. Rarity on the market may be either caused by rarity of a species in the wild or by a limited availability for sale, e.g., due to national protection measures in the range state or remote localities. The present study identified 43 species that are not listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and were only recently described, but have already entered the European pet trade. Ten of these species were selected as case studies, representing species from different geographic regions and illustrating the marketing mechanisms. Many such species that are new to science are neither assessed by the International Union for Conservation of Nature (IUCN) Red List of Threatened Species nor are they covered by international legislation, even though in several countries, where such internationally sought-after species are caught, national protection measures are in place. This paper analyses the challenges and opportunities for the protection of potentially threatened and newly described reptile and amphibian species against over-exploitation for the pet trade.
