Wildlife experts in Africa have known for years that large mammal populations are dwindling outside wildlife reserves, researchers from the University of California, Davis, and Leiden University in the Netherlands report in report.

But new research has found that animal populations are also declining in many of Africa's national parks.

The researchers analyzed that the main reason for this is human activities, and illegal hunting has brought a great impact on the survival of wild animals in many national parks.

They point out that wild animals are hunted for game, "which used to be eaten only by locals, but now it has crossed the ocean and is on the table in Paris and London".

Nonetheless, Africa's wildlife remains the most diverse in the world. This land was once the birthplace of human civilization and is now a protected area for the world's wildlife. Here are the top five animal sanctuaries in Africa.

1. Hwange National Park, Zimbabwe

Hwange National Park is the largest park in Zimbabwe, covering an area of nearly 15,000 square kilometers. There are cheetahs, hyenas, lions, and giraffes there. Thousands of elephants travel to Botswana every year.

The hidden luxury tents in the camp will make you feel like returning to primitive society - the operator will take you to the nearby riverside to watch, and you will see animals still living in peace and contentment in this turbulent home country.

2. Lower Zambezi National Park, Zambia

Compared to neighboring Zimbabwe, which is famous for its tourism industry, Zambia's wildlife tourism is just getting started. The most beautiful place in the Lower Zambezi National Park is the Jongoway River House on the Savannah River, which is built with raw materials such as rocks and branches from the river.

During the day, you can see herds of wild elephants frolicking in the outdoor pools, and groups of hippos pass by on the lawns.

3. Mthethomusha Game Reserve, South Africa

Here you can see paintings left over 2,000 years ago by the original African San people on the stone walls - many paintings are found every year. In addition to the Big Five (lion, leopard, elephant, rhino, buffalo), there are also zebras, eland, and wild dogs. Drive down the valley at night and try delicious traditional South African dishes at the reserve, such as the ostrich steak from Bonhani Hills.

4. Mundulea Nature Reserve, Namibia

A few decades ago, this remote corner of Namibia was just a farm. Now, the vast plains, as well as the jagged hills and precipitous Otavi Mountains in the south of the country, are restored to their former pristine state.

Here, you can see black rhinos named Hook, leopards, eland, impala, zebras, etc., before returning to the residence, you can see the roaring flames and furniture carved from acacia.

5. Gorongosa National Park, Mozambique

Mozambique's seaside is full of luxury resorts that make tourists forget about the many attractions inland. Back in the 1960s, American actor, Cary Grant visited Gorongosa National Park.

Decades of turmoil have decimated animals, and in times of peace, lions, sables, eland, striped antelope, and crocodiles have returned to the desert plains and craters.
