The government of Colombia has announced a plan to control its growing invasive hippopotamus population, including the possible euthanasia of some animals, officials said on Monday.
Environment Minister Irene Vélez said the country will begin a management programme in the second half of 2026 aimed at reducing the hippo population in the Magdalena River region.
The population could grow rapidly
Authorities estimate there are around 200 hippos living in the wild in central Colombia. Officials warn that if no action is taken, the number could rise to nearly 1,000 within the next decade.
The animals are considered an invasive species and are reported to be damaging local ecosystems by affecting water quality and threatening native wildlife such as river turtles and manatees.
Euthanasia and other control measures planned
As part of the plan, the government said around 80 hippos may be euthanized as an initial step to reduce population growth.
The programme will also include other measures such as relocation and confinement, although officials say relocation options remain limited.
Colombia has previously discussed transferring some animals to other countries, including India, Mexico, Ecuador, Peru, and South Africa, but no final agreements have been reached.
Origin traced back to Pablo Escobar
The hippo population in Colombia originated from a private zoo owned by late drug lord Pablo Escobar, who illegally imported four hippos in the 1980s.
Since then, the population has grown without natural predators, raising environmental concerns among scientists and authorities.
Environmental concerns
Officials say uncontrolled growth of the species could cause long-term ecological damage, including disruption of river systems and competition with native species.
The government says urgent action is needed to protect biodiversity and restore balance to affected ecosystems.
Summary
Colombia is preparing a controversial wildlife control programme targeting its rapidly growing invasive hippo population. The plan includes euthanasia of some animals and other population control measures to prevent environmental damage and uncontrolled expansion.
