Rhino dehorning nearly eliminated poaching in African reserves: study, PgII

Key Highlights:

• A study in South Africa's Greater Kruger region showed that dehorning led to a 78% drop in rhino poaching.
• Between 2017 and 2023, the Greater Kruger area lost 1,985 rhinos, despite spending $74 million on anti-poaching.
• 2,284 rhinos were dehorned across eight reserves, using only 1.2% of the total anti-poaching budget.
• The illegal rhino horn trade generated between $874 million and $1.13 billion from 2012 to 2022.

Detailed Insights:

• Dehorning involves safely removing 90-93% of the rhino's horn to deter poachers, as horns are made of keratin and used in traditional medicine.
• The study used hierarchical Bayesian regression modelling to compare reserves that dehorned rhinos with those that did not, tracking poaching changes.
• Reserves that dehorned rhinos saw a 75% decrease in poaching, and dehorned rhinos had a 95% lower risk of being poached.
• Kaziranga National Park in Assam has successfully reduced poaching through smart patrolling and community engagement, without dehorning.
• The study emphasizes the importance of supporting rangers through fair pay, training, and safety, as they are crucial for conservation efforts.
• While dehorning is not a perfect solution, it shows promise as a long-term strategy, helping governments and agencies make informed decisions about resource allocation.

Key Concepts Involved:

• Poaching: The illegal hunting or capturing of wild animals, often for profit.
• Keratin: A fibrous protein that forms the main structural constituent of hair, nails, and rhino horns.
• Anti-poaching: Measures taken to prevent, deter, and combat the illegal hunting of wildlife.
