The northern slopes of the Himalayan mountains lie at a very high altitude, and hence, they are covered with snow for most time of the year. Such extreme environment condition does not support the growth of rich plant life. However, the southern slopes of the Himalayas receive heavy rainfall which results in the growth of thick forests in the region. Hence, the southern slopes in the Himalayan region are covered with thick vegetation as compared to the northern slopes.
