This initiative, a pioneer in Argentina, seeks to integrate forensic DNA into scientific knowledge in judicial investigations on crimes affecting biodiversity.
The main focus is the implementation of precise protocols for the collection, preservation, and analysis of genetic evidence.
Development of the training
On March 10, 2026, more than 50 professionals —including Federal Security Forces, officials from the Public Prosecutor’s Office, and technical personnel for wildlife control— participated in the workshop “Forensic DNA Applied to Judicial Investigations on Illegal Wildlife Trafficking”.
The event was promoted by WCS Argentina, with the support of CONICET, the Argentine Museum of Natural Sciences (MACN), the National Security Ministry, the Argentine Federal Police, and the cooperation of the INL office from the United States.
Strategic objective
The purpose of the training was to strengthen operational capacities through the use of forensic DNA tools. By incorporating technical protocols and scientific knowledge, it aims to improve the quality of genetic evidence to offer a more robust response to organized crime.
The impact of illegal trafficking in Argentina
The illegal wildlife trafficking is a form of transnational organized crime that threatens national security, public health, and sovereignty. Argentina acts as a strategic point of origin, transit, and destination in South America.
-
It is estimated that more than 140 wildlife species are affected in the country.
-
At least 30 species are under threat of extinction.
-
Among the most illegally traded animals are the talking parrot, the toucan, the land turtle, and various monkeys.
Science as a judicial tool
Experts from WCS Argentina and the Ministry of Security agreed that interinstitutional cooperation is vital. Dr. José Pereyra highlighted that this environmental crime often shares routes and logistics with drug trafficking and money laundering.
The use of forensic DNA allows:
-
Precisely identifying the trafficked species.
-
Determining the geographic origin of the specimens.
-
Linking evidence in complex investigations.
-
Detecting criminal patterns and areas of illegal extraction.
Theoretical and practical training
The workshop included modules taught by researchers from CONICET on the fundamentals of species identification and the collection of biological samples to avoid contamination or degradation of probative value. A real case from 2025 was also presented where genetic evidence was incorporated for the first time in an operation.
New Technical Protocol
As a result of the joint work between the MACN and WCS, the “Technical Protocol for the Collection and Preservation of Genetic Evidence” was presented. This document standardizes the handling, documentation, and transfer of samples, ensuring the integrity of the evidence and its validity in the oral trial system.
