The World Heritage Committee recommended extending the national park to include more areas of montane forest. Following a 2005 extension, the National Park includes the whole of the mountain above the tree line as well as the natural forest (montane forest) which was under Kilimanjaro Forest Reserve, and as such fulfils the criteria of integrity. It is important that the extension of the National Park be reflected in the boundaries of the property.
The wildlife of the property is important to the experience of Kilimanjaro, although the property is not inscribed in relation to biodiversity criteria. Pressures on elephant, buffalo and antelope, and logging in the Forest Reserve area, were noted as integrity concerns at the time of inscription. The park is connected to Amboseli National Park, however corridors to Arusha National Park and Tsavo National park have been encroached, impacting on wildlife migration.
