Zimbabwean ivory poachers have killed more than 80 elephants by poisoning water holes with cyanide, endangering one of the world's biggest herds.
Environment minister Saviour Kasuku said the elephants had died in the last few weeks in the Hwange national park, while security forces were preoccupied with a 31 July general election.
Police and rangers recovered 19 tusks, cyanide and wire snares after a sweep through villages close to the park, which is located south of Victoria Falls.
Zimbabwe is home to some of Africa's largest herds, with half of its estimated 80,000 elephants thought to be in Hwange, the country's largest park.
Mr Kasuku, who was appointed to the environment ministry a week ago, said he would push for stiff penalties for convicted poachers, who routinely get less than the nine-year jail term imposed for cattle rustling.
Zimbabwe is working to revive its tourism industry, including its wildlife sector, which has suffered years of decline blamed by some on long-serving President Robert Mugabe's economic policies.
Mr Mugabe and his ZANU-PF party, in power since the former Rhodesia gained independence from Britain in 1980, was re-elected in an election in July.
