Innovative Method to Curb Poaching

The University of the Witwatersrand in South Africa has launched an innovative anti-poaching initiative titled the Rhisotope Project, aimed at protecting the nation’s critically endangered rhinos by utilizing radioactive isotopes. The project, which commenced with a formal launch on July 31, follows six years of rigorous research in collaboration with the International Atomic Energy Agency (IAEA).

Key Highlights of the Rhisotope Project:

• Purpose and Methodology: The project seeks to deter rhino poaching by injecting non-harmful radioactive isotopes into rhino horns, enabling customs agents to easily identify trafficked horns using radiation detection technology. This approach has been designed to be non-invasive and safe for the rhinos.

• Testing and Implementation: Five rhinos were treated at the Waterberg Biosphere Reserve. Prior laboratory endeavors involved the use of 3D-printed rhino horns to simulate conditions and assess detection efficacy, confirming that horns could be identified even when hidden within shipping containers.

• Health Monitoring: An earlier pilot phase involved 20 rhinos treated in June, with health assessments conducted by a research team from Ghent University, Belgium. They monitored cellular damage and found no adverse effects in the treated rhinos as compared to untreated ones.

• Concerns about Rhino Poaching: The global rhino population has dramatically decreased from approximately 500,000 at the start of the 20th century to about 27,000 due to high demand for rhino horns, especially in Asian markets. South Africa, home to about 80% of the world’s rhinos, has witnessed significant poaching, with over 10,000 rhinos lost in the last decade.

• Comparison to Existing Methods: Unlike dehorning, which has proven effective in reducing poaching rates by 78% yet disrupts the social behavior of rhinos, the isotopic tagging method aims to offer a more humane solution without altering the animals' natural behavior.

• Future Aspirations: Researchers are not only focusing on rhinos but also aspire to apply similar techniques to protect other endangered species including elephants and pangolins.

Additional Information:

• Scientific Validation: Chief Scientific Officer James Larkin emphasized the scientific proof of the safety and efficacy of the isotopic tagging process in deterring poaching.

• International Collaboration: The project is underscored by an international partnership aimed at addressing the poaching crisis, reflecting a united front in wildlife conservation efforts.

• Long-term Goal: The overarching aim is to provide a sustainable framework to combat the rhino poaching epidemic and raise global awareness regarding the plight of this species.

Economic Context:

• Illicit Trafficking and Economy: The trafficking of rhino horns is linked to extensive illegal trade networks, contributing to significant economic losses in wildlife conservation and the overall biodiversity of the ecosystems.

This innovative project represents a significant development in conservation strategy, offering a science-based approach to protect not only rhinos but potentially other endangered species facing threats from poaching and illegal trafficking.

Important Points:

• Launch date of Rhisotope Project: July 31.
• Collaboration with the IAEA and support from international teams.
• No harm to rhinos observed in trials; effective identification of poached horns established.
• The global rhino population decline from 500,000 to 27,000 primarily due to poaching.
• Aim to deter poaching without disrupting natural behaviors of animals.
• Future aspiration to extend similar techniques to protect elephants and pangolins.
