The above wiki link is about game wardens in USA. I wonder if they operate along the same as this in Africa....
Game wardens, also known as troopers or wildlife troopers, or conservation officers, have broad duties within the law enforcement spectrum, such as ensuring that licensing requirements are met by hunters, fishermen, and trappers. Detailed investigations are common in order to solve wildlife crimes. Officers in some areas may be responsible for conducting investigations of hunting related homicides and boating accidents. Officers also make arrests of individuals driving or boating under the influence of alcohol or other drugs. Officers use DNA, ballistic, fingerprint, and any other comparative evidence to prosecute criminals that illegally kill wildlife or commit other crimes. Officers can also assist with wildlife management duties such as trapping, hunting in a helicopter or in fixed-wing airplane surveys
