In mountainous regions of India, the natural vegetation largely consists of coniferous forests like pines, firs, and spruces at higher altitudes, along with temperate forests at lower altitudes. This is due to the cooler temperatures, higher rainfall, and specific soil conditions. In contrast, desert areas, like the Thar Desert, experience extremely hot and dry conditions with very low rainfall. Therefore, the vegetation found here is typically thorny bushes, cacti, and acacia trees, which are adapted to conserve water, having small leaves or thorns and deep roots.
