The Western Ghats, also known as the Sahyadri mountain range, is a mountain range that covers an area of 160,000 km2 (62,000 sq mi) in a stretch of 1,600 km (990 mi) parallel to the western coast of the Indian peninsula, traversing the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu. It is a UNESCO World Heritage Site and one of the 36 biodiversity hotspots in the world. It is sometimes called the Great Escarpment of India. It contains a very large proportion of the country's flora and fauna, many of which are endemic to this region. The Western Ghats are older than the Himalayas. They influence Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau and separates the plateau from a narrow coastal plain called the Western Coastal Plains along the Arabian Sea. A total of 39 areas in the Western Ghats, including national parks, wildlife sanctuaries and reserve forests, were designated as world heritage sites in 2012 – twenty of them in Kerala, ten in Karnataka, six in Tamil Nadu and four in Maharashtra.
Gir National Park and Wildlife Sanctuary, also known as Sasan Gir, is a forest, national park, and wildlife sanctuary near Talala Gir in Gujarat, India. It is located 43 km (27 mi) north-east of Somnath, 65 km (40 mi) south-east of Junagadh and 60 km (37 mi) south-west of Amreli. It was established in 1965 in the erstwhile Nawab of Junagarh's private hunting area, with a total area of 1,410.30 km2 (544.52 sq mi), of which 258.71 km2 (99.89 sq mi) is fully protected as a national park and 1,151.59 km2 (444.63 sq mi) as wildlife sanctuary. It is part of the Khathiar-Gir dry deciduous forests ecoregion.
The Khathiar–Gir dry deciduous forests is a mostly arid ecoregion in northwestern India that stretches over 103,100 sq mi (267,000 km2) across Gujarat, Rajasthan and Madhya Pradesh. The dry deciduous forests in the region are dominated by teak, and thorny trees and scrub in drier areas.
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, Live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones.
India is the world's 8th most biodiverse region with a 0.46 BioD score on diversity index, 102,718 species of fauna and 23.39% of the nation's geographical area under forest and tree cover in 2020. India encompasses a wide range of biomes: desert, high mountains, highlands, tropical and temperate forests, swamplands, plains, grasslands, areas surrounding rivers, as well as island archipelago. Officially, three out of the 36 Biodiversity Hotspots in the world are present in India: the Himalayas, the Western Ghats, and the Indo-Burma region. To these may be added the Sundarbans and the Terrai-Duar Savannah grasslands for their unique foliage and animal species. These hotspots have numerous endemic species. Nearly 5% of India's total area is formally classified under protected areas.
The Upper Gangetic Plains moist deciduous forests is a tropical and subtropical moist broadleaf forests ecoregion of northern India.
The Eastern Highlands moist deciduous forests, presently known as East Deccan moist deciduous forests, is a tropical and subtropical moist broadleaf forests ecoregion in east-central India. The ecoregion covers an area of 341,100 square kilometers (131,700 sq mi), extending across portions of Andhra Pradesh, Chhattisgarh, Jharkhand, Madhya Pradesh, Maharashtra, Odisha, and Telangana states.
The Northern dry deciduous forests, presently known as the North Deccan dry deciduous forests, is a tropical dry broadleaf forest ecoregion of east-central India.
Uttar Pradesh is India's fourth largest state by land area, and most populous state, located in the north-central part of the country. It spreads over a large area, and the plains of the state are quite distinctly different from the high mountains in the north. The climate of this state can also vary widely - primarily due to it being far from the moderating effect of the sea and the occasional cold air arising due to western disturbances.
The Himalayan subtropical broadleaf forests is an ecoregion that extends from the middle hills of central Nepal through Darjeeling into Bhutan and also into the Indian States of Uttar Pradesh and Bihar. It represents the east–west-directed band of subtropical broadleaf forest at an altitude of between 500 and 1,000 m along the Outer Himalayan Range, and includes several forest types traversing an east to west moisture gradient.
India is home to a large variety of wildlife. It is a biodiversity hotspot with various ecosystems ranging from the Himalayas in the north to the evergreen rainforests in the south, the sands of the west to the marshy mangroves of the east. India lies within the Indomalayan realm and is home to about 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian, and 6.2% of flowering plant species. India's forests contain about 500 species of mammals and more than 1300 bird species.
Forestry in India is a significant rural industry and a major environmental resource. India is one of the ten most forest-rich countries of the world. Together, India and 9 other countries account for 67 percent of the total forest area of the world. India's forest cover grew at 0.20% annually over 1990–2000, and has grown at the rate of 0.7% per year over 2000–2010, after decades where forest degradation was a matter of serious concern.
The environment of India comprises some of the world's most biodiverse ecozones. The Deccan Traps, Gangetic Plains and the Himalayas are the major geographical features. The country faces different forms of pollution as its major environmental issue and is more vulnerable to the effects of climate change being a developing nation. India has laws protecting the environment and is one of the countries that signed the Convention on Biological Diversity (CBD) treaty. The Ministry of Environment, Forest and Climate Change and each particular state forest departments plan and implement environmental policies throughout the country.
The Indian state of Bihar contains sub-Himalayan foothills and mountains with moist deciduous forests. Rainfall may exceed 1600 millimeters per year. Common trees include Shorea robusta (sal), Toona ciliata, Diospyros melanoxylon (kendu), Boswellia serrata (salai), Terminalia tomentosa (asan), Terminalia bellirica (bahera), Terminalia arjuna (arjun), Pterocarpus marsupium (paisar), Madhuca indica (mahua).
Odisha, a state in eastern India, is extremely diverse and gives the state abundance of natural beauty and wildlife. The districts in the interior are thickly covered by tropical moist deciduous and tropical dry deciduous forests. The hills, plateaus and isolated areas of the northeastern part of the state are covered by the tropical moist deciduous forests whereas the dry deciduous forests are located in the southwest region of the state. Some of the trees which grow in abundance in Odisha are bamboo, teak, rosewood, sal, piasal, sanghvan and haldi. There are 479 species of birds, 86 species of mammals, 19 species of amphibians and 110 species of reptiles present in Odisha. The state is also an important habitat for the endangered olive ridley turtles and Irrawaddy dolphins. Koraput district of southern Odisha has been identified by Food and Agriculture Organisation (FAO) of UN as Global Agricultural Heritage site which is among only other three sites in the world. Other sites are in Peru, China and Philippines.
The Western Himalayan subalpine conifer forests is a temperate coniferous forests ecoregion of the middle and upper elevations of the western Middle Himalayas of Nepal, India, and Pakistan.
Tropical evergreen forests of India are found in the Andaman and Nicobar Islands, the Western Ghats, which fringe the Arabian Sea, the coastline of peninsular India, and the greater Assam region in the north-east. Small remnants of evergreen forest are found in Odisha state. Semi-evergreen forest is more extensive than the evergreen formation partly because evergreen forests tend to degrade to semi-evergreen with human interference. There are substantial differences between the three major evergreen forest regions.The average annual rainfall is 65-75 inches.
Shoolpaneshwar Wildlife Sanctuary is a protected area in India's Gujarat state, located in the western Satpura Range south of the Narmada River and is 607.7 km2 (234.6 sq mi) large. It shares a common boundary with Madhya Pradesh and Maharashtra. It encompasses mixed dry deciduous forest, riverine forest, few pockets of moist teak forest, agricultural fields and two water reservoirs. It was established in 1982.
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur
Biogeographic classification of India is the division of India according to biogeographic characteristics. Biogeography is the study of the distribution of species (biology), organisms, and ecosystems in geographic space and through geological time. India has a rich heritage of natural diversity. India ranks fourth in Asia and tenth in the world amongst the top 17 mega-diverse countries in the world. India harbours nearly 11% of the world's floral diversity comprising over 17500 documented flowering plants, 6200 endemic species, 7500 medicinal plants and 246 globally threatened species in only 2.4% of world's land area. India is also home to four biodiversity hotspots—Andaman & Nicobar Islands, Eastern Himalaya, Indo-Burma region, and the Western Ghats. Hence the importance of biogeographical study of India's natural heritage.
