A life for
the Kalahari

Valentin Grüner is a conservationist and ranger best known for his extraordinary bond with Sirga — a wild lioness he raised from an orphaned cub and has lived alongside ever since. He is the founder of the Modisa Wildlife Project, a 70 km² reserve of wild Kalahari in southwestern Botswana, where he has lived full-time for over fifteen years.

A trained bush pilot, he handles game management, supports anti-poaching operations and acts as a link between local communities and the surrounding conservation areas. In partnership with the remote community of Khawa, Modisa is responsible for 780,000 hectares of wild Kalahari — privately funded and built from the ground up.

Grüner grew up near Lake Constance, Germany.

Sirga

Abandoned as a cub and rejected by her pride, Sirga was taken in by Valentin at just a few days old. He raised her by hand in the Kalahari — not as a pet, but as a lion, with the aim of giving her a life as wild as possible within the realities of the reserve.

Their bond became one of the most documented human–lion relationships in the world, followed by millions on social media and covered by international press. Through Sirga, people around the world are captivated by the Kalahari — and Valentin's work aims to direct that love toward a sustainable future for the land and the wildlife it holds.
