Greater Maasai Mara

Geography and cultural context

The reserve was first established in 1948, and Narok County has been responsible for it since 2013. The Mara Conservancy manages the western Mara Triangle on the county's behalf under a collaboration agreement ³. The reserve's southern boundary meets Tanzania's Serengeti, and its management plan sets a 2 km buffer strip along its other borders ³. The Greater Mara, as defined in recent fencing research, covers 668,500 hectares ⁵⁶.

Land outside the reserve was formally allocated in 1970 as Maasai group ranches. These have since been subdivided into smaller individual parcels, a process still under way in places ⁵. According to a 2018 commentary co-written by MMWCA's then chief executive, individual holdings created in the 1990s were typically about 40 hectares ¹⁸. Subdivision is the backdrop to both the conservancy model and the spread of fences. In February 2025 Narok County's governor signed three linked documents for 2023–2032 into law: a reserve management plan, a spatial plan and a Greater Mara Ecosystem plan ⁴.

Landscape and ecology

Wildlife in the Mara has been declining for decades. Resident wildlife populations fell by more than 70% between the 1980s and the 2000s, according to studies summarised by Løvschal and colleagues ⁵. A study by Joseph Ogutu of the University of Hohenheim found that Kenya's wildlife overall fell by 68% between 1977 and 2018, with the Mara especially hard hit ¹⁴.

Fencing is the most visible recent pressure. Satellite mapping found that fenced land in the Greater Mara grew from 35,067 ha in 1985 to 130,277 ha in 2020, 19% of the ecosystem ⁶. In Pardamat, ground surveys in 2019–2021 recorded 920.6 km of fences enclosing about a third of a 23,400 ha area ⁶.

The Mara–Loita wildebeest population was estimated at 120,000–150,000 in the 1970s and about 26,700 in 2024, on Kenyan government figures ⁷. A December 2025 fact sheet from the Global Initiative on Ungulate Migration links the decline to settlement and fences on the Loita Plains and northern Mara Plains, conversion of savanna to wheat, and more sheep and goat herding ⁷.

Communities and livelihoods

In the conservancy model, tour operators pooled individual Maasai plots into conservancies that are leased to them ¹⁸. MMWCA, founded in 2013 ², says its conservancies have more than 17,000 landowners and receive over US$7 million a year in lease payments from 52 tourism partners; its strategic plan does not say which year that figure covers ¹. It also reports more than 3,200 tourism jobs and more than 510 community rangers, 70 of them women ¹. These are first-party figures.

Independent research points to trade-offs. A 2017 study by Claire Bedelian and Joseph Ogutu found that conservancy payments give households a reliable, year-round income, but that lease income is no greater than what livestock contribute. It also found that conservancies restrict grazing and herd movement, and that because payments follow land title, women and other marginalised groups are left out ¹⁶. In 2019 Al Jazeera reported a dispute in which some landowners said they had been excluded from decisions and that operators took too large a share. Some threatened to leave their leases and fence or farm their land ¹⁷. When tourism collapsed during COVID-19, Conservation International lent more than US$2 million to four Mara conservancies so that operators could keep paying leases ¹⁵.

Tourism model and development

The reserve's management plan describes overcrowding and vehicle congestion in parts of the reserve, and records that more than 150 vehicles have sometimes gathered at a single river crossing ³. A 2016 audit counted 31 lodges and camps with 1,382 beds inside the reserve ³. The 2023–2032 plan bars new accommodation and any increase in bed capacity in all reserve zones, and allows no new or expanded balloon concessions ³⁴. In June 2024 the county banned private vehicles from game drives ¹³. Since 2024, non-resident adults have paid US$200 a day from July to December and US$100 from January to June ¹¹¹². The county says 19% of entry-fee collections go to surrounding communities through a Community Support Fund ⁴. Visitor numbers fell for a second year in 2025, when the Mara drew fewer tourists than Amboseli National Park, according to Business Daily ¹¹.

Lodge building is now in court. The Ritz-Carlton safari camp in the reserve opened in August 2025; a petitioner had alleged that it was built along the Sand River. In February 2026 the High Court struck out that petition, largely on jurisdictional grounds ⁹. In July 2026 the East Africa Law Society, Natural Justice and two other groups filed a new case against it and two other camps, seeking a halt to new or expanded accommodation in the reserve until 2032 ¹⁰. Marriott and the camp's owner say it had the required approvals, and Kenyan authorities have said it lies in a designated tourism investment zone under the 2023–2032 management plan ⁸.
