The Oserengoni Wildlife Sanctuary was founded out of the need to prevent the wildlife in the region from infringing upon the developing communities and vice versa. Enabling this coexistence lies at the heart of the Sanctuary's philosophy, and its success has enabled both wildlife and communities to prosper – we believe that the successful developments of communities and businesses in the region and their safe and successful coexistence with the wildlife in the Conservancy and its adjoining wildlife corridors is proving that conservation works. The Oserengoni Wildlife Sanctuary is very proud of its many achievements, which includes its Rhino, Grevy's zebra and Beisa Oryx breeding programmes, and a general 3-fold increase across all other species. The sanctuary boasts over 40 different mammal species andf5 320 bird varieties including the endangered grey created helmet shrike, African Fish Eagle and Augur Buzzard.
The Sanctuary is 18,000 acres and includes a wildlife corridor and riparian land along the shores of both lakes Naivasha and Oloidien. On both the Northern and Western sides of the Sanctuary are community farms. On the South West are pastoralists who keep cattle, and on the South East is Hell's Gate National park. The game corridor is especially designed, maintained and managed to allow the free and natural roaming of animals between the National Park and the lakes.
The OWC constitutes a relatively large wilderness of dry acacia-dominated woodland, riparian woodlands and vast grasslands, broken by a few rugged hills. We take pride in conserving both indigenous and threatened species, providing protected habitats for all species threatened by the ever-growing human-wildlife coexistence. The OWC is a vital refuge for wildlife displaced as a result of both human population increases and industrial development, and holds a significant proportion of the region's wildlife.
