Gaborone (AP) - At the beginning of his visit to Botswana, British Prince Harry (35) planted trees in the Chobe National Park in the north of the country on Thursday together with 200 elementary school children.

The tree species, also called baobab, is under serious threat in Africa, the prince said on Instagram. The students took the seedlings in recycled cans and mixed earth with dung from an elephant orphanage. "If you care about nature, she'll take care of you," Harry was quoted as saying.

After visiting the national park, the prince wanted to visit another project of his Sentebale Foundation for young HIV-infected people. He also wants to inaugurate a cross-border forest conservation project in the border triangle with Namibia and Angola.

Afterwards, Harry is expected in the afternoon in a mine clearance camp in the southeasternanganese village of Dirico. His wife, Meghan, Duchess of Sussex, stayed in Cape Town on Thursday with her four-month-old son, Archie, to attend an event for women in the civil service.

Harry (35) and Meghan (38) have been on a ten-day trip to Africa since Monday, starting in the South African tourist capital of Cape Town with visits to museums, township projects and a mosque.
