Cross–Niger transition forests in the context of "Imo State"

Abia Listen (Igbo:Alaọha Abia) is a state in the Southeastern region of Nigeria. The state's capital is Umuahia and its most populous city is Aba. The legislature is the Abia State House of Assembly.

Abia is bordered the west by Imo, east by Cross River, south by Rivers, northwest by Anambra and northeast by Enugu and Ebonyi. The state is divided between the Niger Delta swamp forests in the south and the Cross–Niger transition forests. The Imo and Aba Rivers flows along the state's western and southern borders respectively. Known for producing crude oil and natural gas, Abia ranks the eighth by Human Development Index since 2019.

Ebonyi (Igbo: Alaọha Ebonyi Listen) is a state in the South-East geopolitical zone of Nigeria, bordered to the north and northeast by Benue State, Enugu State to the west, Cross River State to the east and southeast, and Abia State to the southwest. Named after the Abonyi (Aboine) River—a large part of which is in the state's south—Ebonyi State was formed from parts of Abia and Enugu state in 1996 and has its capital in Abakaliki.

One of the smallest states of Nigeria, Ebonyi is the 33rd largest in area and 29th most populous with an estimated population of nearly 2.9 million as of 2016. Geographically, the state is divided between the Cross–Niger transition forests in the far south and the drier Guinean forest–savanna mosaic in the rest of the state. The other important geographical features are the Cross River and its tributary, the River Aloma, which flow along Ebonyi's southeastern and eastern borders, respectively; while fellow Cross River tributaries, the Abonyi (Aboine), Asu, and Eze Aku rivers run through the state's interior. There are other smaller rivers like Ichelle and igbe which also form boundaries between Benue and Ebonyi States to the West.
