Difficulty: MediumVegetation Zones and Distribution in Nigeria

An environmental research team mapping ecological zones in Nigeria records an upland area above 1,200 metres elevation characterized by mountain grasslands, stunted trees, gallery forests in sheltered valleys, and temperate floral affinities such as Podocarpus. Which vegetation zone of Nigeria is described in this study?

  1. Montane VegetationAnswer
  2. B
    Guinea Savanna
  3. C
    Sahel Savanna
  4. D
    Mangrove Swamp

Answer

Montane Vegetation is the vegetation zone characterized by upland grasslands, stunted trees, and temperate floral species at high elevations in Nigeria.
Montane vegetation in Nigeria occurs on high plateaus (such as Jos Plateau and Mambilla Plateau) where elevation exceeds 1,200 metres. The lower temperatures at these heights produce unique mountain grasslands, stunted tree growth, and temperate species like Podocarpus.

Step-by-Step Solution

1
Analyze the geographical and physical attributes given in the prompt.
The prompt describes an area with high elevation (>1,200 m), cooler upland temperatures, mountain grasslands, and temperate plant affinities.
Elevation strongly dictates temperature and vegetation zonation in Nigeria.
2
Match the physical features with Nigeria's major vegetation zones.
Upland high-altitude regions like the Jos and Mambilla Plateaus support Montane Vegetation.
Montane zones form isolated ecological islands where altitude modifies the local climate, allowing temperate species and mountain grasslands to thrive.
