The magnitude of legal wildlife trade and implications for species survival https://www.oliverstringham.com/publications/magnitude-legal-wildlife-trade-species-survival/ Tue, 14 Jan 2025 00:00:00 +0000 https://www.oliverstringham.com/publications/magnitude-legal-wildlife-trade-species-survival/ Using two decades of U.S. wildlife import records (2000–2022), we show that the United States traded over 21,000 species and 2.85 billion individuals, with more than half of individuals from most taxa sourced from the wild. The scale of legal trade far exceeds prior assessments, limiting decision-makers' ability to gauge its impact on species survival. United States amphibian imports pose a disease risk to salamanders despite Lacey Act regulations https://www.oliverstringham.com/publications/us-amphibian-imports-disease-risk-salamanders/ Tue, 16 May 2023 00:00:00 +0000 https://www.oliverstringham.com/publications/us-amphibian-imports-disease-risk-salamanders/ A 2016 U.S. rule restricted trade in 20 salamander genera to prevent introduction of the fungal pathogen Bsal. Analyzing import data from 1999–2021, we found the rule reduced trade in the targeted taxa, but many other amphibian genera and species now known to carry Bsal continue to be imported in large quantities, leaving a persistent disease introduction risk. The U.S. market for imported wildlife not listed in the CITES multilateral treaty https://www.oliverstringham.com/publications/us-market-non-cites-wildlife/ Fri, 07 Oct 2022 00:00:00 +0000 https://www.oliverstringham.com/publications/us-market-non-cites-wildlife/ CITES regulates trade in a subset of at-risk species, but most wildlife imported into the U.S. isn’t covered by the treaty at all. We compared U.S. imports of CITES-listed and non-CITES-listed live wildlife and found non-listed imports involve 3.6 times more species and 11 times the trade quantity, exposing a major gap in international trade monitoring.
