Which of the Nigeria states is Northern guinea savanna located?

Analyze the question: You're asked which listed state lies in the Northern Guinea savanna vegetation zone of Nigeria.

Concept: Vegetation zones of Nigeria (south to north)

1. Mangrove/Freshwater swamp forest (coastal areas)
2. Tropical rainforest (e.g., Ondo, Edo, Cross River)
3. Guinea savanna, which has two parts: • Southern Guinea savanna: Oyo, Kwara, Kogi, Benue, Niger (southern part) • Northern Guinea savanna: Kaduna, Kano (southern parts), Bauchi, Plateau, Niger (northern part), Katsina (southern parts), Taraba
4. Sudan savanna (e.g., Kano, Katsina, Jigawa, Zamfara, Sokoto)
5. Sahel savanna (far northeast, e.g., Borno, Yobe)

Step-by-step elimination:

• A. Borno: Mostly Sahel savanna, so no.
• B. Kano: Lies in the transition between Northern Guinea and Sudan savanna. Among the options, it is the one commonly associated with the Northern Guinea savanna belt. Plausible.
• C. Oyo: Mainly derived savanna and forest-savanna mosaic, with the northern part in Southern Guinea savanna. Not Northern.
• D. Kwara: Mostly Southern Guinea savanna, so no.

Note on precision: Strictly speaking, Kano sits largely in the Sudan savanna, with its southern parts in the Northern Guinea savanna.

Answer: B. Kano

Exam tip: Remember the order going north: Rainforest → Southern Guinea → Northern Guinea → Sudan → Sahel. Then match states: Oyo/Kwara = southern Guinea, Kaduna/Kano/Bauchi/Plateau = northern Guinea and beyond, Borno/Yobe = Sahel. When you see a Northern Guinea question, pick the option that is farthest north without being in the extreme northeast.
