उत्तर
On the slopes of the mountains-we find changing vegetation belts according to the altitude upto the snow line. On the lower slopes of the Eastern Himalayas we find broad-leaved evergreen trees the Laurel Oak, Magnolia. Above this we find deciduous trees and still higher we have the coniferous trees, Spruce, Silverfir, Pine, Chir Pine. On the Western Himalayas there are broad- leave evergreen trees but not so as those on the Eastern Himalayas. Chennar and Silverfir are the two most important trees of the Srinagar valley slopes. Still higher above 6000 metres there is only snow.
