In a newly released photo on the royal couples shared Instagram account @SussexRoyal, the Sussexes shared a special photo from their 2017 trip where Harry walks towards an elephant.
"Two years ago on World Elephant Day, The Duke and Duchess of Sussex joined Dr Chase to help in this conservation effort," the new parents wrote on Instagram.
In another shot shared to social media, Meghan's hand is seen gently holding an elephants trunk.
38-year-old Meghan and 34-year-old Harry also announced they had joined forces with American talk show host Ellen DeGeneres and her wildlife fund.
“These collars allow the team at EWB to track the elephants, as well as to learn their essential migratory patterns to keep their corridors safe and open so future generations of elephants can roam freely,” the couple wrote.
“In honour of this amazing support, EWB have named their most recently collared Elephant…ELLEN! We can’t wait to see where she will go! 🐘”
Botswana has a special meaning for the couple, with Prince Harry taking Meghan Markle to the African wilderness after they first met in 2016.
Talking immediately after their 2017 engagement, the Duke of Sussex recalled their time spent in Botswana.
"I managed to persuade her to come and join me in Botswana. We camped out with each other under the stars. She came and joined me for five days out there, which was absolutely fantastic,” he said.
“So then we were really by ourselves, which was crucial to me to make sure that we had a chance to know each other."
Prince Harry and Meghan Markle have confirmed they'll be undertaking a royal tour to South Africa in Spring, announcing they will also be taking baby Archie along with them.
