Uttarakhand is the state located at the foothills of the snow-clad Himalayas with lush green vegetation. There is a diverse range of flora and fauna habitat in Uttarakhand. The State has rich and diverse floral, faunal and microbial wealth including rare and threatened species of plants and animals.
Well known for the famous Jim Corbett National Park, one of the habitations of the flora and fauna in the state. The Royal Bengal Tigers are also found here. The Rajaji National Park which is a rainforest area is known for its Elephants and the Valley of Flowers National Park which is an alpine forest and has several herbs, shrubs, roses, and a variety of Rhododendrons.

The flora and vegetation of the state range from tropical deciduous to alpine vegetation; broadly categorized into three major types :
1. Sub-Tropical Zone of Uttarakhand -
This kind of forest zone lies between the altitude of 300 m and 1500 m and comprises of the following forest communities:

Chir / Pine Community:- This evergreen plant community is mainly found in dry hill slopes between 1200 m to 1800 m. The forest floor is often clear. However, Pyrus Pashia, Dalbergia Sericia, Caseana Elliptica, Syzygium Cumini are other species that grow with pine.
Vijaysar Community:- It is a deciduous type of plant community found in shady and wet places ranging from 800 m to 1500 m in altitudes. The trees Sapium Onsigne, Dalbergia Sissoo, Syzygium Cumini are few among other species.
Ramal Community:- This is a deciduous plant community mainly found on eroded slopes or riverine areas. This community has mainly Mallotus Philippinensis, Toona Serrata, etc plants.

2. Sub-temperate forest of Uttarakhand -
The forest communities of this zone are generally found at 1800 m to 2800 m altitudes. The plant communities which belong to this zone are :
Deodar Community:- The evergreen communities of plants is found between 1800 m to 2200 m altitude. The shrubs which belong to this community are Rubus Ellipticus and Berberis Asiatica.
Utis Community:- This deciduous plant community is generally found between 1400 to 2200 m altitudes. Some of the important species of this community are Rubus Ellipticus and Betula Alnoides.

Kal Community:- This evergreen forest resides from 2100 meters to 2800 meters altitude.
Banj oak Community:- This is also an evergreen plant community found between 1800 m and 2200 m altitude.
Rianj Oak Community:- Same as above two this community is also evergreen and is found from 2000 to 2500 m in altitude. Myrica Esculenta, Betula Alnoides, Pyrus Pasia are among the other tree species of this community. This community also attains the same attitudinal range as mentioned for Banj Oak forest.

3. Sub Alpine and Alpine Forest of Uttarakhand -
The altitude above 3,000 meters is generally considered a zone of sub-alpine and alpine vegetation. The tree species are represented by Pinus Wallichiana, Abies pindrow, Prunus Cornuta, Acer Cesium, Betula Utilis (Bhoj Patra), and Salix sp. Species of the genera Cotoneaster, Rosa, Berberis, Ribes, Junipers, Rhododendron Anthropogenic, Rhododendron Campanulas are the shrubby components of the zone. The herbaceous vegetation is represented by many species of genera Po ten till, Primula, Aster, Saxifrage, Achaean, Delphinium, Polygonal, Corydalis, Pleurospermum, Meconopsis, Pedicularis, Saussurea, Rheum, Silene, etc. The Bugyals of this zone are well known for a rich and diversified flora.

The floral diversity is further exhibited by the species that grow in the rain shadow areas of Uttaranchal. Such species develop adaptive characters to survive the wrath of adverse climate. Labium rhomboid, Thylacospermum caespitosum, Acantholimon lycopodioides, Dracocephalum heterophyllum, etc. are a few such examples.
