Statement Regarding Free-Ranging Hippos in Colombia

In Colombia, there are free-ranging hippos who escaped from the house of drug lord Pablo Escobar. As they have no predator in Colombia they breed very fast. However, it is invasive species and the breeding has to be controled. You can read the Hippo Specialist Group Statement Regarding Free-Ranging Hippos in Colombia here.

The Hippo Specialist Group was granted

The chair of IUCN SSC Jon Paul Rodriguez granted Hippo Specialist Group for its outstanding contribution in delivering the Species Strategic Plan and the excellent work carried out during the 2020.

Dead hippo in DCR

Dead hippo was found in the DRC province of South Kivu near the village Ake. Therefore, the army arrested five people suspected of killing of the animal. However, the incident needs to be investigated. Hippos are protected  and killing is a crime. One of the projects of our specialist group (HSG) takes place in this area.
