In Katavi National Park, like other protected areas in Tanzania, wildlife poaching is a serious challenge. This is because the park has no fence, and any person can easily enter and kill animals if he is lucky enough to walk out uncaught. According to the African Wildlife Foundation (AWF) website, more elephants are dying from poaching than from natural causes or conflict with humans. Their body parts are traded illegally as trophies, traditional medicine, or trinkets on a lucrative black market - but these iconic pachyderms are not the only wildlife species to be slaughtered for human gain. Big cats like lions and cheetahs are killed for their bones; African wild dogs and other large carnivores die at the hands of villagers protecting their livestock. "We often arrest and bring them to justice so that the law takes its course. But we urge the people to stop such acts as we are well prepared and anyone who enters the park for criminal acts, will be arrested and taken to court," says Francis Konde, acting head of Katavi National Park. Situated about 1,500km from Dar es Salaam, Katavi is the third largest national park in Tanzania. It hosts more than 100,000 wild animals and is a popular tourism destination among locals and foreigners.
