Nigeria is home to a broad range of plants and animals. This rich natural endowment is a product of the climatic variations resulting into various north-south gradations of habitats and ecosystems. Habitats support more than 1,340 species. Several animals, such as the Nigerian mole rat, live nowhere else on Earth. Apart from the most remote areas, people and animals are often in competition for land. There are nearly 400 species of animals and plants at risk, including lions, crocodiles, monkeys, trees, and fish.
