With the promulgation of Decree 46 of 1999, now Act 46 (Cap 65 LFN 2004), in 1999 two additional national parks; Kamuku and Okomu were established.
However, Yankari was delisted as a national park following a request by the Bauchi State Government in June 2006, reducing the number of national parks to seven.
Nigeria has rich and unique array of ecosystems, and a great variety of wild fauna and flora.
This rich natural endowment is a product of the climatic variations resulting into various north-south gradations of habitats and ecosystems.
The habitats support more than 1,340 species of animals among which is 274 mammalian species, making it the 8th highest in Africa.
