The National Reserve is situated in Rift Valley Province, Narok and Transmara Districts. It is the ampliation of the Serengeti National Park along the Kenya-Tanzania border. The Masai-Mara National Reserve is Kenya’s most-visited protected area, world famous for its flora and fauna: its high density of herbivores and predators, and the annual migrations of Wildebeest.
The Maasai Mara lies in the Great Rift Valley long from Ethiopia’s Red Sea through Kenya, Tanzania, Malawi and into Mozambique. It is characterized by a wide valley and a towering escarpment.
Habitats in the Maasai Mara are varied, including grassland, riverine forest, Acacia woodland, swamps, non-deciduous thickets, boulder-strewn escarpments, and Acacia, Croton and Tarchonanthus scrub. The permanent Mara and Talek Rivers flow through the Reserve. 

The flora

Given the factors drought , fire and crash land by large herbivores , the National Reserve Masai Mara is dominated by species of resistant grasses. The rich grasslands are spotted riparian forests and rocky outcrops of dark quartz.

The most common grass in the Masai Mara is the red oat grass ( Themeda triandra ) . In its early stages of growth, this species is very palatable and nutritious and form the food base of herbivores through these pastures.

The rains seen the rapid growth of several species of different herbs , for which of course depend on the huge herds from the migration of wildebeest and zebras.

The migration

The Masai Mara Migration is one of nature’s most spectacular events in the world. Visitors should bear in mind that even though the migration is one of Africa’s most remarkable displays, the Masai Mara is one of Africa’s best wildlife destinations year round.

Every July the wildebeest migrate north in vast numbers from the Serengeti plains in search of fresh pasture, and return south around October – November. The Great Migration is one of the most spectacular wildlife experiences nature has to offer, involving an immensity of herbivores: some 1,300,000 wildebeest, 360,000 Thomson’s gazelle, and 200,000 zebras. These numerous migrants are followed along their annual circular route by hungry predators, most notably lions, cheetahs and hyenas.

A dangerous barrier for the migratory zebras and wildebeest is the Mara River, with the largest crocodiles found in East Africa. The crossing of the Mara river by these herds is one of the most fabulous times of the Great Migration. It is not rare to find professional photographers, film makers and animal lovers by the Mara river waiting the animals crossing.

The fauna

The Masai Mara is one of the best known and most famous reserves in the whole of Africa and sustains some of Africa’s largest and most varied wildlife populations. Almost all animals of the African continent are represented since the park shelters about 80 kinds of mammals and more than 450 varieties of birds. It is also famous for the Big Five (Rhinoceros, Leopard, Cape Buffalo, Elephant and Lion) and the Great Migration.

The Masai Mara wildlife is on permanent show: large resident herds of animals (zebras, antelopes, elephants, giraffes, buffalo, Thomson’s and Grant’s gazelles, impalas, topis… ) and their predators (lions, leopards, cheetahs, hyenas…) are prevalent all year round. Hippos are abundant in the Mara River as are very large Nile crocodiles (among the largest in Africa)!

Large numbers of predators inhabit the Masai Mara and you may witness a hunt, a lion hunting may be which is pretty common in the Mara seldom witnessed in other parts of Africa.
