Q. Which forest type dominates north-western Madhya Pradesh with under 75 cm rainfall?
Answer: Thorn forests
Notes: North-west Madhya Pradesh lies in the Central Indian Plateau with <75 cm annual rainfall. Thorn forests dominate as they are drought-resistant, unlike moist deciduous or evergreen forests needing more moisture. The Gwalior forest division is part of this thorn forest region, adapted to arid climatic conditions with sparse, xerophytic vegetation.
