2.1 History
The Masai Mara National Reserve is the keystone of the Greater Mara Serengeti Ecosystem, a safe haven for the great migration, a powerhouse of sustainable economic benefits, and a living testimony to the Maasai community’s conservation ideals and affinity with wildlife. This purpose is further elaborated in the individual programme purpose statements which are provided at the beginning of each of the four management programmes. The Masai Mara National Reserve was first established in 1948, when the Mara Triangle, a 520 square kilometre area between the Siria escarpment, the Tanzanian border and the Mara River, was declared a National Game Reserve. 
 As its name suggests, the Masai Mara National Reserve is therefore unique amongst Kenya’s protected areas in its role as a cultural and natural heritage of the Maasai. The purpose that the MMNR serves is not simply to provide a sanctuary for wildlife and revenue generation through tourism, but also as a living and vivid testimony to the Maasai’s traditional conservation-compatible and wildlife tolerant pastoralist livelihood. Since the Maasai communities’ traditional land use practices are responsible for the preservation of the Reserve’s exceptional natural resources in the first place, it is also important that the benefits that are now being derived from these resources are first and foremost channelled back to these communities. 
Around the time of Kenya's independence, the Sanctuary became a “Game Reserve” and was expanded to cover the eastern portion as well. At this time, the land was brought under control of the Narok County Council (NCC). In 1974, the status changed from Game Reserve to National Reserve (Walpole et al. 2003:x). While Kenyan National Parks are managed by the central government, all National Reserves are held in trust, and managed, by County Councils .Following the status change, a few major grazing areas were removed from the reserve and attached to existing group ranches. This action reduced the overall area of MMNR and allowed Maasai to continue using areas that their cattle had grazed in recent years (Lamprey and Reid 2004). More recently, part of NCC was separated to become the TransMara County Council (TMCC). TMCC then took control of the western Mara Triangle which was under its jurisdiction. TMCC has granted management of the Triangle to the Mara Conservancy, a non-profit organization (Walpole et al. 2003), while NCC continues to manage the eastern two-thirds of the Reserve by itself to encompass an area of 1,831 square kilometres. 
In 1984, parts of Reserve were excised to provide access to watering points for livestock, and the Reserve was brought to its present size of 1,530 square kilometres, as shown in Figure 2 opposite.  In 1995, following the creation of the Trans Mara District, the control of the Reserve was split between the County Councils of Narok and Trans Mara. This situation remains today, with the CCN responsible for the Reserve to the east of the Mara River, and the CCTM responsible for the Reserve to the west of the river (still known as the Mara Triangle). In 2001, the day-to-day management of the Mara Triangle was contracted to an independent non-profit protected area management company, the Mara Conservancy, under an initial five-year management agreement. This management agreement was extended for a further ten years in 2006.
Surrounding areas are managed as group ranches by Maasai communities. However, the Kenyan government has promoted subdivision of group lands into private ranches. 85% of respondents to a recent survey expected some positive effects of this subdivision, particularly the anticipated increased security of property rights. However, 56% also noted likely negative impacts such as reduction in available grazing areas. The survey found that many community members anticipate a shift in livelihood and/or land use if their ranch is subdivided (Seno and Shaw 2002)..
Despite these changes in the size and management of the Reserve in the 60 years since the area’s initial gazettement, the MMNR has throughout this time provided a vital refuge for wildlife, most notably the elephant and Black rhino populations, and for the spectacular annual large mammal migrations. In addition, as a result of the area’s high popularity with visitors, the Reserve has also generated significant economic benefits at both the local level (through employment, benefit sharing, and tourism-related enterprises) and at the national level, where the MMNR has proved to be a driving force for tourism to the country as a whole. These major functions that the Reserve has played correspond with oral testimony given by local residents on the reasons the Reserve was gazetted, which states: “it was the intention that the game reserve should be Maasai owned. The idea was for African participation and to serve tribal interests by conserving wild life for the material improvement of the Maasai”.
