Answer Details
The Savanna zones of Nigeria have a limited amount of rainfall, which means that there is not enough water for many trees to grow. Also, the area is often exposed to grazing animals, which can prevent tree growth. Additionally, farmers in the area often engage in bush-burning, which further reduces the number of trees. Therefore, a fewer number of trees is a characteristic of the Savanna zones of Nigeria.
