In the decade following possibly one of the worst poaching incidents in Southern Africa, which left at least 300 dead after poachers laced watering holes and salt licks with cyanide, crimes against wildlife have drastically declined in Zimbabwe's largest national park. Investigations conducted by the Zimbabwe Parks and Wildlife Management Authority (ZimParks) revealed that the deaths were due to cyanide poisoning. The horrendous crime, which made international headlines in 2013, led to the deaths of an estimated 300 elephants and is believed to have been carried out by well-organized poaching syndicates.
