The Duke of Sussex, Prince Harry, on Monday joined an anti-poaching patrol with local park rangers in Malawi to highlight conservation work, another leg of his African tour.

The Duke of Sussex arrived in Malawi on Sunday, met President Peter Mutharika and also visited a college to meet young women whose education is partially supported by The Queen's Commonwealth Trust.

Prince Harry also visited to Malawi's Liwonde National Park, where he paid tribute to former British soldier Guardsman Mathew Talbot, who was killed in May while taking part in counter-poaching operations in the country.

He also joined an anti-poaching patrol with local park rangers and witness an anti-poaching demonstration conducted by local rangers and the U.K. military.

The Duke of Sussex, writing in The Daily Telegraph ahead of his national park trip, said conservation was "fundamental to our survival.”

"This may well sound hippy to some," he wrote.

"But we cannot afford to have a 'them or us' mentality. Humans and animals and their habitats fundamentally need to co-exist or within the next 10 years our problems across the globe will become even more unmanageable.”

While Prince Harry is visiting the third country since his arrival in Africa last week, the Duchess of Sussex, Meghan and their four-month-old son Archie are still in South Africa.

This is the royal couple's first official trip since the birth of Archie, who was born in May. It is also the first time Meghan is visiting South Africa.

Prince Harry is scheduled to rejoin his family in South Africa for a township visit on Wednesday near Johannesburg. They will also meet Graca Machel, widow of South African anti-apartheid icon Nelson Mandela, and meet President Cyril Ramaphosa before returning for London.
