Serengeti National Park is one of the best-known wildlife sanctuary in the world, unequalled for its natural beauty and scientific value. It is part of the Serengeti ecosystem in the Mara and Simiyu regions. It has an area of around thirteen thousand square kilometres – larger than some countries. It is known for a unique combination of diverse habitats. The eco system at this place supports more than 30 species of large herbivores and nearly 500 species of birds. The climate here is usually warm and dry.
Heavier rain falls in the park area from March to May. Rainfall of less intensity is generally experienced in October and November. The average rainfall for the park varies from about 50 cm in the highlands to about 120 cm on the shores of Lake Victoria. Lush greenery appears after the rains which is followed by a gradual drying period. It is during this drying period that animals migrate in search of permanent waters.
Serengeti annual migration – considered by many biologists to be one of the great wonders of the world – occurs roughly from May to November. This involves movement of around a million wildebeest and zebra. The movement also attracts predators drawn by the availability of such large numbers of prey. Apart from the rhinos, which have been decimated by poachers, and the hunting dogs, which are slowly declining, the Serengeti is alive and well. The wildebeest and buffalo populations have multiplied, benefitting the main predators such as Lion. Experts say that the ecosystem at Serengeti is volatile and easily affected by drought, disease or overgrazing. Several conservation programs are in place to keep the natural beauty alive to be enjoyed by generations to come.
