- At least 110 countries are now involved in illegal trade in wildlife — more than doubling from 49 in 2000. Trade connections jumped by more than 400%, according to a recent analysis of global wildlife seizure data.
- Asia, rather than Europe, is now the center of illegal trade for most species, the study found, sparked by extensive trading, business and diplomatic connections with Africa — the source for many wildlife products.
- This trade, often run by transnational criminal syndicates, is complex and resilient to disruptions, such as the pandemic or border restrictions, and adapts quickly, making intervention and enforcement extremely challenging.
- Experts say constant monitoring and transnational law enforcement efforts are needed to crack down on this rapidly evolving illegal enterprise.
Wildlife trade is decimating the planet’s biodiversity, driving declines in more than 31,500 wild species and spreading infectious zoonotic diseases that jump between wildlife, livestock and humans.
In addition to massive legal, regulated trade, there’s widespread illicit trafficking in both live animals and high-demand, profitable animal products, a commerce worth at least $20 billion per year. Dubbed “one of the world’s largest criminal activities,” wildlife ranks among the most lucrative smuggled goods, a list that includes guns, drugs and humans — but with way lower risks.
Yet, there’s patchy data on how this trade has grown over the years; what species are trafficked; and where the hotspots are. What we do know comes from law enforcement seizures, which are often just the tip of the iceberg.
“Much of what we know about [illegal wildlife trade] is based on static estimates, isolated case studies or regional snapshots, rather than long-term, system-level analyses,” said researcher Tow Jia Hao at the National University of Singapore. “[It] is a difficult picture to piece together and tackle, especially with much of the pieces still being hidden.”
To fill the knowledge gaps, Hao and his colleagues analyzed data on illegal wildlife trade from the last two decades (2000 – 2019), and compared it with legal trade data.
They gathered seizure data from TRAFFIC’s Wildlife Trade Portal and collected information on permitted wildlife trade from the CITES legal trade database, which records all legitimate commerce in species listed under a global wildlife treaty, CITES. They mapped out source and destination countries and tracked trade routes.
Their analyses revealed that wildlife trafficking networks are complex and resilient and can easily shift trade routes and source countries as needed.
It also uncovered shocking growth in illicit networks that now spiderweb across the globe: The number of countries involved more than doubled from 49 in 2000 to 110 in 2019, and trade connections jumped by more than 400%. Their findings were published in the journal Conservation Biology.
“Wildlife trade has grown exponentially … with increasing connectivity among countries, providing more opportunities for wildlife products to move across continents,” Hao said. “While some countries remain as hubs in the network, trade links have been established directly between supplier and consumer countries.”
Hao and his colleagues also discovered that illegal trade is no longer confined to a small set of routes or actors: It’s now highly spread out, happening in countries on every continent, with Asia, Africa and Europe being key hubs.
Asia, Europe and North America are current hotspots of legal trade.
“The study underscores how trafficking groups are highly flexible, able to shift transport routes, target different species and modify their modes of transportation in response to enforcement pressure, trade restrictions and changing market conditions,” Michelle Anagnostou said. She’s a wildlife crime researcher and Banting Fellow at the University of Oxford who was not involved in the study.
Asia is now a center of illegal wildlife trade
Prior to the 2010s, European countries were the top importers of both legal and illegal wildlife and acted as transit hubs for global trade. But as Asia’s middle class grew wealthier, starting in the 1980s, the demand for wildlife products surged — particularly in China and Vietnam.
Endangered tigers poached from India in large numbers were smuggled to China — a trade that still continues. And as pangolins, turtles and other species dwindled in Asia, Africa became the target. For example, since 2008, when Chinese pangolin (Manis pentadactyla) numbers had plummeted by 90%, poached pangolins began pouring out of Africa headed for China, where they’re coveted for meat and scales used in traditional Chinese medicine (TCM).
Between 2005 and 2010, Asia emerged as the hotspot for illegal trade, with Africa being the prominent source.
“Asia overtook Europe as the main center of illegal imports, particularly for high-profile taxa such as pangolins, rhinoceroses, large cats, reptiles and [other] species used in traditional medicine,” Has said.
Today, he said, “Europe remains a major market for both legal and illegal wildlife commodified products such as skins and live specimens, whereas demand for TCM-related wildlife products [is] centered around Asia.”
The deepening economic ties between the African and Asian continents have opened direct routes for wildlife trafficking, the researchers say. From 2000-24, China loaned at least $180 billion to 49 African governments and invested nearly $60 billion in infrastructure projects across the continent.
China’s Belt and Road Initiative, a transcontinental transport corridor launched in 2013, has also unlocked new trade routes between Europe, Asia and Africa through which wildlife products — and people — flow.
Smuggling wildlife, like all illegal activity, requires complicity, corruption and an eroded rule of law, and there’s evidence of collusion with government officials.
For example, the U.K.-based NGO Environmental Investigation Agency (EIA) uncovered deals between Chinese-led criminal gangs and corrupt Tanzanian officials to smuggle huge quantities of ivory — which is regarded as a status symbol in China. Their collusion helped kill more than half of the country’s elephants in just five years between 2009 and 2014.
In 2005, when President Jakaya Kikwete assumed office, there were about 142,000 elephants in the country. By late 2015, when he stepped down, that number plummeted to about 55,000. Most of the ivory from these elephants went to China, and Chinese diplomats were also involved in smuggling ivory, EIA’s report found.
Vietnam, a major destination for South African rhino horns since 2006, has seen similar trends, with its nationals involved in smuggling rhino horns and pangolin scales. In March 2026, South African authorities arrested two Vietnamese rhino horn smugglers for illegally exporting 98 horns from a game reserve.
Pangolins are another victim. A 2020 study found that 65% of the nearly 300,000 pangolins seized in Nigeria were destined to China and Vietnam between 2012 and 2019.
Anagnostou called Asia’s rise as a hub “unsurprising” but said the findings also show that Europe remains a primary market, surpassing North America, South America and Oceania.
Europe continues to be a destination for wildlife smuggled from Hispanic America, especially for reptiles and exotic pets, because laws don’t prohibit trade in wildlife removed illegally from their source countries. Another high-value commodity in illicit commerce is the critically endangered glass eels — baby European eels (Anguilla anguilla) shipped to China for aquaculture, raised to be served there as popular, pricey cuisine.
“This has significant policy implications: High-income countries that have historically taken a back seat in wildlife enforcement may need to assume a far more central role in tackling illegal wildlife trade within their own borders,” Anagnostou said.
Illegal wildlife trade networks are complex and resilient
International criminal networks, the researchers found, are resilient to global disruptions, such as the COVID-19 pandemic. Although commerce came to a near-grinding halt with borders closed during the early days of the pandemic, illegal wildlife trafficking continued — slow at first, but then picking up. For instance, the rhino horn trade in Asia decreased in 2020, but shot up a year later as traffickers shifted from planes to ships to move goods and avoid quarantine restrictions.
“The COVID-19 pandemic seemed to only slow the flow of wildlife trade, despite global trade disruptions and initial hesitation towards wildlife products surrounding the origin of the virus,” Hao said. “It highlights how overwhelming the demand for wildlife products is, and how suppliers will find a way to meet demand, regardless of restrictions.”
Illicit trade is also quick to shift when certain species receive protections. When European eels were regulated under CITES in 2009 and export was banned outside the EU a year later, smugglers targeted new grounds: first, North Africa for European eels and then North America and the Caribbean for American eels.
Since this analysis relies on reported seizures, the researchers say this is an underestimate of the true scale of wildlife trade. Not all seizures are tallied: Noncharismatic animals, such as amphibians and insects, often go undetected or unreported, and not all criminals are caught.
Tackling this hydra-headed problem of illegal wildlife trade needs consistent monitoring, Anagnostou said, “to keep pace with changing dynamics, and to ensure enforcement efforts remain effective.”
By pointing out hubs of illegal commerce, this research helps authorities prioritize high-risk trafficking paths, Hao said. “Strengthening cooperation between linked source, transit and destination countries, through joint investigations, intelligence sharing and targeted border controls can help break established routes and reduce the resilience of illegal wildlife trade networks.”
