Ecological indicators in a derived savanna disturbed by oil spillage and vegetation fire in Nigeria
Introduction Guinea and Sudan savannas covering about 546,400 sq.km.,representing 60％ of the entire Nigerias land mass,harbor a significant proportion of Nigerias population who are engaged mainly in nomadic and arable farming and are where a larger proportion of Nigerias domestically grown food is produced.Oil pipelines that transverse these grasslands are frequently subjected to vandalization by restive youths which cause oil spillage and vegetation fire (NEST,1991).This study examined the indicators of this growing ecological problem in Nigerias savannah ecosystem.
