The global economy of wildlife trafficking

Wildlife trafficking is a complex transnational phenomenon situated at the intersection of conservation, illicit markets, global trade, and governance systems. It refers to the illegal taking, transportation, and trade of wild animals and plants, including their parts and derivatives, in contravention of national laws or international agreements such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). While public discourse often centres on a limited set of “charismatic” species, the contemporary wildlife trade is far broader in scope. Recent analyses by the United Nations Office on Drugs and Crime (UNODC) indicate that illegal wildlife trade has been detected in at least 162 countries and territories, involving approximately 4,000 species, emphasising the extent to which wildlife trafficking is embedded in globalised economic systems. This article sets out what wildlife trafficking actually is, what is being traded, where and how it happens, and why it matters, before turning to what is being done, and what still needs to change.

The commodities involved in wildlife trafficking are highly heterogeneous, reflecting diverse forms of demand across global markets. Animal parts and derivatives are typically the most associated with wildlife trafficking, including ivory, rhino horn, pangolin scales, and big cat bones, usually trafficked for luxury consumption and status signalling, or use in traditional medicine. However, a considerable proportion of trafficking involves live animals, particularly for the exotic pet trade, which encompasses birds, reptiles, amphibians, and small mammals. In parallel, plant trafficking constitutes a significant, though often under recognised, component of the trade, such as high-value timber species such as rosewood, as well as orchids and medicinal plants. Marine species, including seahorses, corals, and eels, are increasingly targeted, reflecting both expanding demand and regulatory gaps in ocean governance. Bushmeat trafficking is also seen, ranging from localised subsistence use to commercialised cross-border trade. 

Geographically, wildlife trafficking operates across interconnected global supply chains that link biodiversity-rich source regions with major consumer markets. Source areas are frequently located in parts of sub-Saharan Africa, Southeast Asia, and Latin America, where high biodiversity coincides with economic marginalisation, limited enforcement capacity, and, in some cases, political instability. Transit routes often pass through major logistical hubs, including international ports, airports, and free trade zones, where high volumes of legitimate trade provide cover for illicit flows. Destination markets are typically concentrated in urban centres where purchasing power and consumer demand are greatest. In many case, countries occupy multiple roles simultaneously, acting as sources, transit points, and destinations depending on the commodity and network configuration. Indeed, large-scale enforcement operations coordinated by INTERPOL and the World Customs Organization, involving over 130 countries, illustrate the extent to which wildlife trafficking is embedded within global trade infrastructures.

The organisation of wildlife trafficking reflects broader patterns of transnational organised crime. Networks involved in the trade often operate across multiple stages of the supply chain, from extraction and collection to transport, distribution, and retail, frequently exploiting weak regulation and enforcement and corruption to facilitate movement across borders. Trafficking networks employ sophisticated methods, including the use of shell companies, falsified documentation, and complex routing strategies designed to obscure the origin and destination of illicit goods. Digital technologies are also increasingly being used in the trade, with online platforms and social media facilitating both retail-level transactions and connections between suppliers and buyers. Wildlife products are frequently concealed within legal shipments, transported through passenger luggage or postal systems, or laundered into legal markets through misdeclaration or blending with licensed goods. These practices mirror those observed in other illicit markets, reinforcing the view that wildlife trafficking should be analysed within the broader framework of organised crime rather than as a distinct category.

The impacts of wildlife trafficking are complex and extend beyond biodiversity loss. Ecologically, the removal of species at unsustainable rates contributes to population declines, local extinctions, and the disruption of ecosystem functions. The targeting of keystone or highly interactive species can generate cascading effects that alter ecological systems. Indeed, wildlife crime has contributed to local and global extinctions in some taxa. From a socioeconomic perspective, wildlife trafficking affects livelihoods, particularly in communities that depend on sustainable resource use or ecotourism. It also exacerbates inequality, as profits are often concentrated amongst intermediaries and criminal networks rather than local populations. The trade is frequently associated with drug trafficking, human exploitation, corruption, money laundering, and the erosion of state authority. Moreover, there are emerging concerns regarding public health, as the capture, transport, and sale of wild animals can facilitate zoonotic disease transmission. 

Efforts to address wildlife trafficking have expanded over the past two decades, combining international regulation, law enforcement cooperation, and demand reduction strategies. CITES remains the central multilateral framework, regulating international trade through a system of permits and listings that aim to ensure sustainability. However, its effectiveness relies on national implementation and enforcement capacity. To strengthen responses, the International Consortium on Combating Wildlife Crime (ICCWC), which brings together CITES, UNODC, INTERPOL, the World Bank, and the World Customs Organization, supports countries in developing legal frameworks, conducting threat assessments, and improving criminal justice responses. Large-scale enforcement initiatives, such as UNODC’s GUARD Wildlife programme is currently focused on strengthening enforcement capacity and international cooperation, particularly in Africa and Asia, while INTERPOL and WCO’s annual Operation Thunder now represents one of the largest recurring global enforcement efforts against wildlife and forestry trafficking. In 2025, the Operation reported nearly 30,000 live animals seized, 4,640 seizures overall, and 1,100 suspects identified across 134 countries. At the same time, there has been growing emphasis on addressing demand, particularly in key consumer markets, through behaviour change campaigns and regulatory measures.

Despite these efforts, challenges remain. Enforcement responses are variable, with limited resources and competing priorities constraining action in many countries. Trafficking networks continue to adapt rapidly, shifting routes, commodities, and methods in response to interventions. Furthermore, policy approaches have historically focused on individual species or conservation outcomes, sometimes overlooking the broader structural drivers of the trade, including poverty, inequality, and global demand patterns. Recent analyses suggest that more effective responses will require a shift towards integrated strategies that combine conservation and criminal justice approaches. This includes strengthening financial investigations to disrupt profit flows, enhancing monitoring of online markets, supporting community-based conservation initiatives, and addressing the socioeconomic conditions that enable participation in illicit trade.

In sum, wildlife trafficking is a global, adaptive, and deeply embedded phenomenon that requires intersectoral strategies. Its persistence reflects not only the value of wildlife commodities but also the structural conditions that facilitate illicit trade in a globalised economy. As such, it demands responses that are equally systemic, combining international cooperation, national enforcement, and broader efforts to reshape the economic and social contexts in which the trade operates.
