THE VEGETATION OF KATSINA PROVINCE, NIGERIA.

The article focuses on the vegetation of Katsina province in Nigeria. Katsina province is located across Africa from Senegal to the Sudan zone, where rainfall is sufficient for agriculture, however, it does not support a vegetation cover because of its density that is too difficult to clear with primitive tools, moreover, the area is free from tsetse fly. The survey has covered an area of about 3,500 square kilometers and was carried out by making traverses along the motorable tracks followed by an interpretation of aerial photographs. The result shows that the vegetation of Katsina province is largely controlled by biotic factors wherein, all the better soils are heavily cultivated as the province is in the final stage of transition from shifting to sedentary cultivation
