What is the vegetation of the Himalayas?

The mountain range in Asia known as the Himalayas is 1,500 miles long and spread out over five countries: India, Pakistan, Nepal, Bhutan, and China. It has 50 mountains that are over 23,600 feet in elevation, including Mount Everest, the world's highest mountain. You can imagine that in such a vast area, a wide variety of vegetation can be found.
In the eastern and central foothills are tropical and subtropical broadleaf forests. Due to the varied soil, topography, and rainfall levels, these contain an abundant variety of plant life including bamboo, Ceylon ironwood, oaks, and horse chestnuts. On steeper slopes at slightly higher elevations are alders and Himalayan screw pines.
At middle elevations, temperate broadleaf, conifer, and mixed forests can be found. Predominant trees include oak, maple, cedar, chir pine, blue pine, fir, and morinda spruce. There is also an abundance of smaller plants such as ferns, lichen, and orchids.
At higher elevations, the alpine zone has shrublands and grasslands. Widespread vegetation includes moss, lichens, juniper, and rhododendrons.
The Himalayas are particularly known for an abundance of rhododendrons and orchids. There are over 30 sub-species of rhododendron, the national flower of Nepal, in Nepal alone. Additionally, Nepal is home to almost 400 varieties of orchids.
