Early warning of trends in commercial wildlife trade through novel machine-learning analysis of patent filing

Unsustainable wildlife trade imperils thousands of species, but efforts to identify and reduce these threats are hampered by rapidly evolving commercial markets. Businesses trading wildlife-derived products innovate to remain competitive, and the patents they file to protect their innovations also provide an early-warning of market shifts. Here, we develop a novel machine-learning approach to analyse patent-filing trends and apply it to patents filed from 1970-2020 related to six traded taxa that vary in trade legality, threat level, and use type: rhinoceroses, pangolins, bears, sturgeon, horseshoe crabs, and caterpillar fungus. We found 27,308 patents, showing 130% per-year increases, compared to a background rate of 104%. Innovation led to diversification, including new fertilizer products using illegal-to-trade rhinoceros horn, and novel farming methods for pangolins. Stricter regulation did not generally correlate with reduced patenting. Patents reveal how wildlife-related businesses predict, adapt to, and create market shifts, providing data to underpin proactive wildlife-trade management approaches

Prevalence of sustainable and unsustainable use of wild species inferred from the IUCN Red List of Threatened Species

Unsustainable exploitation of wild species represents a serious threat to biodiversity and to the livelihoods of local communities and Indigenous peoples. However, managed, sustainable use has the potential to forestall extinctions, aid recovery, and meet human needs. We analyzed species-level data for 30,923 species from 13 taxonomic groups on the International Union for Conservation of Nature Red List of Threatened Species to investigate patterns of intentional biological resource use. Forty percent of species (10,098 of 25,009 species from 10 data-sufficient taxonomic groups) were used. The main purposes of use were pets, display animals, horticulture, and human consumption. Intentional use is currently contributing to elevated extinction risk for 28–29% of threatened or near threatened (NT) species (2752–2848 of 9753 species). Intentional use also affected 16% of all species used (1597–1631 of 10,098). However, 72% of used species (7291 of 10,098) were least concern, of which nearly half (3469) also had stable or improving population trends. The remainder were not documented as threatened by biological resource use, including at least 172 threatened or NT species with stable or improving populations. About one-third of species that had use documented as a threat had no targeted species management actions to directly address this threat. To improve use-related red-list data, we suggest small amendments to the relevant classification schemes and required supporting documentation. Our findings on the prevalence of sustainable and unsustainable use, and variation across taxa, can inform international policy making, including the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, the Convention on Biological Diversity, and the Convention on International Trade in Endangered Species.Fil: Marsh, Sophie M.

Understanding consumer demand for bushmeat in urban centers of Cameroon with a focus on pangolin species

Bushmeat consumption remains significant in urban Central Africa. Increasing urbanization has fueled bushmeat trade and become a threat to endangered species like the pangolin. Behavioral change interventions may help reduce demand for pangolins in urban centers. However, there is still a lack of adequate locally-specific research on consumer behavior and drivers of demand to effectively guide such interventions. Our study addressed this knowledge gap through semistructured interviews to investigate consumer preferences and bushmeat consumption habits and perceptions of 597 participants in Bertoua and Ebolowa, Cameroon. Bushmeat, in general, was positively perceived as a tasty, healthy, and luxurious item that meets cultural needs, while domestic meat was negatively perceived as an unhealthy and intensively processed product. The biggest barriers to bushmeat consumption were its illegality and high price. Pangolin was among the most desired types of bushmeat. Nearly half of pangolin consumers were willing to pay more for a pangolin meal. Despite being fully protected by national laws, pangolins were consistently found in local bushmeat markets and restaurants, suggesting the ineffectiveness in law enforcement and/or communication with the public about the legal protection and current status of pangolins. Our findings provide an understanding of sociocultural consumer behavior and drivers that can help guide bushmeat demand reduction interventions in urban centers of Cameroon

Taking a more nuanced look at behavior change for demand reduction in the illegal wildlife trade

The illegal wildlife trade threatens the future of many species, and undermines economies and livelihoods. Conservationists have largely responded with supply‐side interventions, such as antipoaching patrols, but these often fail to stem the tide of wildlife trafficking. There is now increasing interest in demand‐side interventions, which seek to lower poaching pressure on sought‐after species by reducing consumer's desire for, and purchase of, specific wildlife products. Individual behavior change approaches, from environmental education to social marketing, have been widely advocated by academics, practitioners, and policy makers. However, this is an emerging field and we lack the breadth of evidence needed to understand and predict the potential outcomes of demand reduction interventions. To help us gain broader insights, we examine the literature from public health and international development on the effectiveness of behavior change interventions, and critique the current conceptualization of strategies for reducing consumer demand in the illegal wildlife trade. We show that behavior change is difficult to achieve and interventions may have unintended and undesirable consequences because of unaddressed systemic, cultural and environmental drivers, and limited resourcing. We conclude that some sections of the conservation community are advocating a shift from one reductionist approach based on limiting supply, to another based on limiting demand, and argue that conservationists should learn from the public health and international development projects that have integrated systems thinking. By accounting for the multiple interactions and synergies between different factors in the wildlife trade, we can develop more strategic approaches to protecting endangered species

Insights into the status and distribution of pangolins in Togo (West Africa)

Pangolins are considered among the most threatened mammal species, both globally and also in Africa. However almost nothing is known on their status and distribution across wide areas of their range, including Togo (West Africa). We assessed the status and distribution of pangolin species in Togo. Fieldwork was undertaken in five localities around the Fazao Malfakassa National Park, five sites around Togodo Protected Areas Complex (Togodo North and Togodo South National Parks), “Les Deux Béna” and Missahohe Forest Reserves, Yikpa-Dzigbe, Evou and Afagnan Community Forests. In all of these protected areas and forest islands, only one pangolin species was recorded: the white-bellied pangolin (Phataginus tricuspis), with no records of the giant ground pangolin (Smutsia gigantea), a species that now appears unlikely for Togo. Due to the pangolin’s nocturnal behavior spotlighting was carried out as an index of relative abundance and calculated as the Kilometric Index of Abundance (KIA). Our results indicate that P. tricuspis is relatively abundant in suitable habitats in Fazao-Malfakassa National Park, in Togodo North National Park and in the Assoukoko Forest Reserve. These habitats mainly reflect dense remnant forest patches where numerous termite mounds and ant nests occur. The present study provides significant scientific information on the status of pangolins in Togo that can help inform the development of a conservation programme for this species in Togo
