Illicit wildlife trafficking poses a threat to the conservation of species and ecosystems, and represents a fundamental source of biodiversity loss, alongside climate change and large-scale land degradation. Despite the seriousness of this issue, little is known about various socio-cultural demand sources underlying trafficking networks, for example the forthright consumption of endangered species in different cultural contexts. Our study illustrates how wildlife trafficking represents a wicked problem at the intersection of criminal enforcement, cultural heritage and environmental systems management. As with similar network-based crimes, institutions are frequently ineffective at curbing wildlife trafficking, partly due to the lack of information detailing activities within illicit trading networks. To address this shortcoming, we leverage official government records documenting the illegal trade of reptiles in Colombia. As such, our study contributes to the understanding of how and why wildlife trafficking persists across robust trafficking networks, which are conduits for a broader range of black-market goods. Leveraging geo-spatial data, we construct a multiplex representation of wildlife trafficking networks, which facilitates identifying network properties that are signatures of strategic trafficker behavior. In particular, our results indicate that traffickers’ actions are constrained by spatial and market customs, a result which is apparent only within an integrated multiplex representation. Characteristic levels of sub-network coupling further indicate that traffickers strategically leverage knowledge of the entire system. We argue that this multiplex representation is essential for prioritizing crime enforcement strategies aimed at disrupting robust trade networks, thereby enhancing the effectiveness and resources allocation of institutions charged with curbing illicit trafficking. We develop a generalizable model of multiplex criminal trade networks suitable for communicating with policy makers and practitioners, thereby facilitating rapid translation into public policy and environmental conservation efforts.

Historically, the poaching of wildlife was portrayed as a small-scale local activity in which only small numbers of wildlife would be smuggled illegally by collectors or opportunists. Nowadays, this image has changed: criminal networks are believed to be highly involved in wildlife trafficking, which has become a significant area of illicit activity. Even though wildlife trafficking has become accepted as a major area of crime and an important topic and criminologists have examined a variety of illegal wildlife markets, research that specifically focuses on the involvement of different criminal networks and their specific nature is lacking. The concept of a ‘criminal network’ or ‘serious organized crime’ is amorphous – getting used interchangeably and describes all crime that is structured rather than solely reflecting crime that fits within normative definitions of ‘organized’ crime. In reality, criminal networks are diverse. As such, we propose categories of criminal networks that are evidenced in the literature and within our own fieldwork: (1) organized crime groups (2) corporate crime groups and (3) disorganized criminal networks. Whereas there are instances when these groups act alone, this article will (also) discuss the overlap and interaction that occurs between our proposed categories and discuss the complicated nature of the involved criminal networks as well as predictions as to the future of these networks.

Urban wildmeat consumption can contribute to significant declines in wildlife populations, ecosystem function, and food insecurity security. Describing types of individuals involved in illegal urban wildmeat trafficking can help distinguish ordinary citizens from members of criminal organizations and urban vs. rural dimensions of the activity. This research aimed to: (1) create and apply a typology for urban wildmeat traffickers and sellers; and (2) explore linkages between types of urban wildmeat traffickers and sellers. We used focus groups with experts in the Republic of the Congo, February 2019 (N = 2, n = 7–10) to achieve objectives and focused on pangolins, great apes, and dwarf crocodiles. Participants generated risk rankings for each species, typology and city; data was encoded and indexed. Results illustrate heterogeneity in actors involved in the illegal supply chain. Business sideliner and trading charity trafficker types were associated with the highest total risk to wildlife trafficking. A similar pattern of divergence was detected for seller typologies; hidden and casual sellers were associated with the greatest total risk in Pointe Noire and Brazzaville, respectively. Differentiating but not stove piping stakeholders involved in urban wildmeat trafficking will help clarify stages of illegal supply chains as well and promote thinking about new sectors to involve in interventions and solutions, particularly in urban ecosystems thought to be outside the scope to wildlife crime.

The report presents a collection of case studies to illustrate the mechanisms and modalities of corruption in real terms - how it facilitates the movement of wildlife shipments through all stages of the supply chain from source to market, and how it obstructs the criminal justice response, allowing criminal networks to operate with impunity. This report also highlights the harm caused by corruption and urges strong coordinated action to counter it. Wildlife crime and corruption must be addressed in a more connected way, rather than being treated as two separate issues in law enforcement responses. Levelling the playing field will require an innovative and collective approach on the part of all stakeholders to identify the high-risk areas for corruption, develop the means to prevent, investigate, and prosecute corrupt activities, and establish a robust framework to tackle corruption along the wildlife supply chain.

The fine wool Shahtoosh obtained from the Tibetan Antelope (Pantholops hodgsonii Abel, 1826) which is endemic to Tibetan Plateau, is highly valued for its rarity, warmth and lightness. The illegal trade in Shahtoosh may lead to extinction of this species. The Tibetan Antelope is protected from commercial trade throughout its range, both nationally and internationally thereby prohibiting any commercial use or trade of any product in India and in the international market. Though globally banned the illegal trade of Shahtoosh driven by international demand has continued to be actively operational undercover in India. In order to bypass this trade ban, the traffickers mis-declare Shahtoosh consignments as Pashmina, Cashmere or conceal by mixed them in shipments between look-alike woolen products. In the present study the illegal Shahtoosh trade was analysed from 2009 to 2020. The Wildlife Crime Control Bureau has envisaged Operation Soft Gold to curb this. A total of 62 confirmed Shahtoosh cases were detected in India from 2009 to 2020. Most of them were detected at exit points and intended for international smuggling. The Indri Gandhi International airport New Delhi in India was the most preferred airport, while Air Cargo and Air Courier were often used by the traffickers. Our analysis shows that the illegal Shahtoosh trade network is going on between the Western Asian countries, Oman, China, Japan, Pakistan, UK, Spain, Hong Kong and Switzerland are either destination or transit countries for illegal Shahtoosh products.

This study examines the possession of Tigers (Panthera tigris) as pets in Mexico through statistical analysis of governmental seizures on a period of 11 years, a review of socio-political factors related to this phenomenon and an analysis of a particular illicit supply network of a Tiger (P. tigris) specimen seized from a criminal group in northern Tamaulipas, Mexico. We found that socio-political factors such as the prohibition on the use of animals for circuses; environmental regulation strategies; the dominance of criminal groups in most of the Mexican territory and their traditional interest in exotic animals have an influence in the presence of tigers in private homes and ranches. This study contributes to the theoretical understanding of the possession of exotic animals, wildlife illegal networks and wildlife trafficking in Mexico.

In Deep Waters: India's sea cucumbers in illegal wildlife trade – found at least 101.40 tonnes and 6,976 sea cucumber individuals in illicit wildlife trade in India for 2010-2021. It was released ahead of World Fisheries Day on 21 November 2022, a day dedicated to highlighting the critical importance of healthy ocean ecosystems and the need to ensure sustainable fisheries stocks. The report looked into the reasons behind the unsustainable sea cucumber trade and found that demand for sea cucumbers in East Asian and Southeast Asian markets, along with the ease of harvest and low processing costs (drying), are proving detrimental to the species and their survival in India. According to the seizure reports, Sri Lanka, China, and Southeast Asia were the top three destinations for sea cucumbers trafficked from India. The new report also provides action points to help curb the illegal sea cucumber trade in India, including a detailed recommendation on future research priorities, enhancing capacity for interdiction by law enforcement agencies, devising policies and promoting community engagement and awareness.

An intrepid investigation of the criminal world of wildlife trafficking--the poachers, the traders, and the customers--and of those fighting against it. Journalist Rachel Nuwer plunges the reader into the underground of global wildlife trafficking, a topic she has been investigating for nearly a decade. Our insatiable demand for animals--for jewelry, pets, medicine, meat, trophies, and fur--is driving a worldwide poaching epidemic, threatening the continued existence of countless species. Illegal wildlife trade now ranks among the largest contraband industries in the world, yet compared to drug, arms, or human trafficking, the wildlife crisis has received scant attention and support, leaving it up to passionate individuals fighting on the ground to try to ensure that elephants, tigers, rhinos, and more are still around for future generations.

The illegal wildlife trade is one of the most lucrative transnational crimes in the world. Numerous wildlife are threatened with extinction due to overexploitation for food, medicine, and as pets. Although it is difficult to quantify the illegal wildlife trade due to its mostly clandestine nature, analyzing seizure data can indicate its magnitude. Wildlife seizure records from the DENR, PCSDS, and other sources for the period 2010–2019 were collated and analyzed to identify species threatened by the illegal wildlife trade, hotspots, and trafficking routes. The 10-year seizure dataset involved 511 incidents, 283 taxa, and 44,647 wildlife individuals. Reptiles (n = 16,237 individuals) and birds (n = 6,042) were the top seized live wildlife, while pangolin scales (>2,100 kg) had the most quantity and seizure frequency among derivatives. Intervention policies on the key source, transit, and destination locations were proposed to address illegal wildlife trade in the country.

The present report is the fourth iteration of TRAFFIC’s analysis on the illegal trade in Tigers Panthera tigris looking at an overall 19-year trend from 2000 to 2018. Previous analyses reviewed seizures from the 2000–2010, 2000–2012 and 2000–2015 periods. This analysis involved largely Tiger Range Countries (TRCs), while information opportunistically gathered from outside TRCs has also been included to provide a more comprehensive picture of the illegal trade in Tigers. Beyond highlighting the statistics, this report provides insights into trends and the most current and urgent threats facing Tigers. Nineteen years is a considerable time frame for data aggregation, and admittedly numerous changes have occurred in the wildlife protection and management regimes, including of Tiger habitats in a number of TRCs. With the large dataset spanning almost two decades, various considerations emerge involving TRCs and issues concerning the protection of wild Tigers, as well as those arising from captive facilities implicated with illegal Tiger trade. Overall, a conservative estimate of 2,359 Tigers were seized from 2000 to 2018 across 32 countries and territories globally. These occurred from a total of 1,142 seizure incidents, with 95.1% (or 1,086 incidents) occurring in the 13 Asian TRCs1 , accounting for a minimum of 2,241 Tigers seized. On average, 60 seizures were recorded annually, accounting for almost 124 Tigers seized each year. The top three countries with the highest number of seizure incidents were India (463 or 40.5% of total seizures) and China (126 or 11.0%) closely followed by Indonesia (119 or 10.5%).
