Finn's Take· TL;DRWhat started as a drug kingpin's exotic whim has become Colombia's most unusual environmental disaster. Colombian officials on Monday authorized a plan to cull dozens of hippos roaming freely through a region in the center of the country, where they threaten villagers and displace native species years after notorious drug lord Pablo Escobar brought in the first ones. Vélez said up to 80 hippos would be affected by the measure.
The hippos are the descendants of four brought to the country in the 1980s by Escobar as he built a private zoo in Hacienda Nápoles, a gigantic ranch in the Magdalena River valley with a private landing strip that served as his rural abode. After Escobar's death in 1993, the animals were left behind and began breeding rapidly in Colombia's ideal climate. A study published by Colombia's National University estimated that around 170 hippos were roaming freely in the country in 2022.
Colombia is the only country outside of Africa with a wild hippo population. According to official data, the population could reach 500 animals by 2030 if control measures are not implemented. The massive mammals, which can weigh over four tons, have spread far beyond their original home, with hippos recently spotted in areas that are more than 100 kilometers (60 miles) north of the ranch.
Colombian authorities have spent years and substantial resources trying to control the hippo population through humane means. Environment Minister Irene Vélez said previous methods to control their population have been expensive and unsuccessful, including neutering some of the animals or moving them to zoos. The environment minister said the government evaluated for years alternatives such as sterilization and international relocation, but none have been sufficient to contain population growth. "This ministry has carried out enormous diplomatic efforts, and at this moment no country wants to take responsibility," Vélez said in remarks to Blu Radio.
One significant obstacle is genetic deterioration within the hippo population. All current hippos descend from just four individuals, which has caused inbreeding and malformations. "The gene pool is too limited, and individuals with mutations have already been found," Vélez said. "There are visible deformities, such as in the snout, and probably other genetic damage." This genetic bottleneck makes the animals unsuitable for relocation to international zoos or breeding programs.
The expanding hippo population poses serious risks to both local ecosystems and human communities. Environmental authorities in Colombia say the mammals pose a threat to villagers who have encountered them in farms and rivers. They also compete for food and space against local species such as river manatees. In addition to the genetic component, authorities warn that hippos represent a direct threat to native species, such as manatees and turtles, and also affect water quality in rivers and wetlands.
The culling operation will be costly and complex. The cost per hippo can reach up to $14,000, including sedation, the operation and final disposal through on-site burial, according to Blu Radio reports. A scientific study cited by the government recommends removing at least 33 animals per year to achieve a significant reduction.
The decision has sparked fierce opposition from animal rights activists who view the culling as unnecessarily cruel. Andrea Padilla, a senator and animal rights activist who helped draft a law against bullfights in Colombia, described the plan to cull the hippos as a "cruel" decision, and accused government officials of trying to take the easy way out. "Killings and massacres will never be acceptable," Padilla wrote on X. "These are healthy creatures who are victims of the negligence" of government entities.
Paradoxically, the hippos have become an unexpected tourist draw. Despite the challenges, the hippos have also become a tourist attraction, with residents of villages surrounding Hacienda Nápoles offering hippo spotting tours and selling hippo-themed souvenirs. The former drug lord's ranch now operates as a theme park where the hippos remain a major attraction, creating an economic dilemma for local communities that benefit from hippo tourism but face the animals' environmental and safety threats.
This unprecedented situation highlights the lasting consequences of wildlife trafficking and the complex challenges of managing invasive species. As Colombia moves forward with its controversial plan, the legacy of Pablo Escobar's exotic menagerie continues to shape environmental policy decades after his death.
