Summary Ol Ari Nyiro (OAN) which was also called Laikipia Nature Conservancy (LNC) stands out among other conservation areas in the greater Laikipia region for two main reasons. First, it remains the largest privately protected area in the area covering 400 km2, encompassing the most diverse habitat types from grass lands, high forest to riverine vegetation. Secondly, its the only conservancy in Laikipia without livestock, exclusively dedicated to nature conservation following the complete eradication of cattle ranching in 1998. A remarkable improvement in biodiversity richness has been witnessed since then, with significant increase in vegetation cover.
Site description Its located on the Eastern wall of the Rift Valley, the Conservancy is the most important water catchment area for Lake Bogoria and Lake Baringo among other ecological benefits for the riparian community. Its located on the Laikipia Plateau, lying between Longitudes 36017' and 36029' E and between latitudes 00029' and 00042'N.
Key Biodiversity Besides the presence of a variety of large mammals, very high species diversity of relatively inconspicuous, but equally important biota has been documented in Olari Nyiro Conservancy-comprising of 14 amphibians (i.e. frogs and toads), 55 reptiles, 477 birds, more than 800 vascular plants and 755 macro-invertebrates. Amongst these are globally endangered species of mammals and birds, including the critically endangered Wild Dog Lycaon pictus ,Cheetah, Reticulated Giraffe, Greater Kudu, African Elephant and a large population of Lions.
