The sanctuary has successfully reintroduced many endangered species such as, White Rhino, Grevy's Zebra, Beisa Oryx, Wildebeest, Topi and Greater Kudu. The effect of conservation on the natural habitat and the increase of species, has led Oserian Wildlife to be a sanctuary filled with diverse flora and fauna found nowhere else in Kenya or East Africa.
Any profits generated from tourism are dedicated to the conservation of the Oserian Wildlife Sanctuary and the Oserian Game Corridor. The funds go into sustaining the wildlife, the habitat and supporting the surrounding communities.
