In 2008 Rhino Ark commissioned an environmental and social impact audit of representative samples of venues where the Rhino Charge event has been held. The venues assessed were Tassia Ranch (Mukogodo Division, Laikipia), Swuari Lagha (Wamba Division, Samburu), Ol Kinyei Group Ranch (Mara Division, Narok), and Lorongoswa Group Ranch (Kajiado). The audit was carried out by African Conservation Centre.
