write a long essay on vegetation of Himachal Pradesh
Answers
Answer:
The Forests of Himachal Pradesh known for their grandeur and majesty are like a green pearl in the Himalayan crown.
This life supporting systems are presently under great stress due to impact of modern civilization, economic development and growth in human and cattle population.
According to National Forest Policy, 1988, at least two third of the geographical area should be under forest in the hilly states like Himachal Pradesh.
However, keeping in view that about 20 % of the area is inaccessible and beyond the tree limit, the State Government aims to bring 50% of the geographical area under forest cover.
The forests of the State have been classified on an ecological basis as laid down by Champion and Seth, and can be broadly classified into Coniferous Forests and broad-leaved Forests.
Distribution of various species follows fairly regular altitudinal stratification.
The vegetation varies from Dry Scrub Forests at lower altitudes to Alpine Pastures at higher altitudes.
In between these two extremes, distinct vegetational zones of Mixed Deciduous Forests, Bamboo, Chil, Oaks, Deodar, Kail, Fir and Spruce, are found.
The richness and diversity of our flora can be gauged from the fact that, out of total 45,000 species found in the country as many as 3,295 species (7.32%) are reported in the State.
More than 95% of the species are endemic to Himachal Pradesh and characteristic of Western Himalayan flora, while about 5% (150 species) are exotic, introduced over the last 150 years.
The forests of Himachal Pradesh are rich in vascular flora, which forms the conspicuous vegetation cover.

More than 95% of species are endemic to Himachal and characteristic of Western Himalayan flora, while about 5% (150 species) are exotic introduced over the last 150 years.
Forest Cover As we move from lower to higher altitude in the state, variation in vegetation pattern can be noticed easily.
Dry scrub vegetations are prominent at lower altitude, alpine meadows at higher altitude.
Dry deciduous forest, moist deciduous forest, pine, oak, and deodar mixed coniferous and temperate broadleaved forest zones are found in between these two extremes.
Altogether, 20 different vegetation zones can be identified in the state. Generally, these vegetation zones are synchronous to altitudinal stratification.
Micro-climatic changes, due to the effect of slope and aspect, break the continuity in vegetation zones in some part of the state.
