Colombia has launched a program to sterilize hippopotamuses living near the former ranch of Pablo Escobar. These animals are descendants of four hippopotamuses illegally imported from Africa by the drug lord in the 1980s. This was reported by U.S. News.
As part of a government initiative to control the population, which has significantly increased along the rivers in the Antioquia province, two male and one female hippopotamus have been sterilized.
Experts note that in Colombia, hippopotamuses have no natural predators, and their population growth may pose a threat to other species inhabiting the region. Consequently, last year the country's government recognized hippopotamuses as a 'toxic invasive species' and developed a population control program. This plan includes sterilizing 40 hippopotamuses annually, transferring some animals to other countries, and conducting partial culling.
According to reports, the sterilization of hippopotamuses is a complex and risky task that requires significant time and financial resources. The cost of the procedure for one animal is $9,800. Additionally, it carries risks for both the animals, who may experience allergic reactions to anesthesia, and for the veterinarians.
David Echeverri Lopez, head of the environmental protection department, shared with the press the difficulties his staff faces when capturing hippopotamuses. These animals weigh over 3 tons and are territorial, making them aggressive when approached. According to Lopez, the situation is exacerbated by frequent rains and dense vegetation in the area. The abundance of food complicates the use of bait, making the capture of hippopotamuses nearly impossible.
According to the Colombian government, the current population is around 169 individuals. Projections indicate that without intervention, it could grow to 1,000 individuals by 2035.
