Dehorning Rhinos Slashes Poaching in South Africa's Greater Kruger

  • Researchers led by Dr. Tim Kuiper published a seven-year study on June 5 showing that dehorning 2,284 rhinos across eight Greater Kruger reserves cut poaching by 78%.
  • The study arose from reserve managers' concern over persistent rhino losses despite $74 million spent on anti-poaching efforts between 2017 and 2021, with systemic corruption and ineffective law enforcement undermining results.
  • The research analyzed 1,985 poaching incidents over 2.4 million hectares spanning 11 reserves, revealing that dehorning reduces poaching incentives by removing valuable horns, though 111 dehorned rhinos were still killed.
  • Dr. Kuiper reported that dehorning rhinos, which accounted for just a small fraction of the total conservation funding, resulted in a 95% decrease in poaching risk—from 13% down to 0.6% annually; nonetheless, issues such as horn regrowth and persistent poaching due to leftover horn stumps remain challenges.
  • The study concludes that dehorning is a highly effective but temporary tactic that can buy time to tackle deeper drivers like horn demand, inequality, corruption, and criminal networks, emphasizing the need to empower local communities.
