Bauchi state has two distinctive vegetation zones, namely, the Sudan Savannah and the Sahel Savannah. Sudan savannah vegetation covers the southern part of Bauchi state where the vegetation gets richer and richer towards the south, especially along water sources or rivers, but generally, the vegetation is less uniform and grasses are shorter than what grows even farther south, that is, in the forest zone of the middle belt.
Sahel type of the savannah, which is also known as the semi-desert vegetation, becomes manifest from the middle of the state as one moves from the state’s south to its north. This type of vegetation comprises isolated stands of thorny shrubs. On the other hand, the southwestern part of the state is mountainous as a result of the continuation of the Jos Plateau, while the northern part is generally sandy.
Yankari has become the most developed wildlife park in Nigeria with a lot of attractions for visitors with a wide variety of flora fauna. The park is famous for its variety of animals available for viewing around the year, though the animals are better watched between November and May period of the dry season when the animals converge around the Gaji River in the park.
