The Upper Gangetic Plains moist deciduous forests is a tropical and subtropical moist broadleaf forests ecoregion of northern India.
It lies on the alluvial plain of the Ganges and Yamuna rivers, with an area of 263,100 square kilometers (101,600 sq mi), covering most of the state of Uttar Pradesh and adjacent portions of Uttarakhand, Haryana, Madhya Pradesh and Bihar; as well as a minuscule adjacent portion of southern Nepal.
The ecoregion is bounded on the north by the Himalayan subtropical pine forests, Terai-Duar savannas and grasslands and Himalayan subtropical broadleaf forests of the Himalaya foothills, to the west by the drier Northwestern thorn scrub forests and Khathiar-Gir dry deciduous forests, on the south by the Narmada Valley dry deciduous forests of the Malwa and Bundelkhand uplands, and on the east by the more humid Lower Gangetic Plains moist deciduous forests.
The ecoregion is home to several large cities, including Delhi, Agra, Kanpur, Lucknow, Gwalior, and Varanasi.
The ecoregion has a subtropical climate. Rainfall is highly seasonal, falling mainly during the June-to-September southwest monsoon.
In ancient times the region was mostly covered with moist semi deciduous forests, with trees that lose their leaves during the winter dry season. sal (Shorea robusta) is predominant tree. Mature trees form a canopy 25 to 35 metres. Other trees include Terminalia tomentosa, Terminalia belerica, Lagerstroemia parviflora, Adina cordifolia, Dillenia pentagyna, Stereospermum suaveolens , and Ficus spp. [1]
Where the land has been disturbed by flood, fire, or livestock grazing there are areas of grassland or savanna, with the grasses Saccharum spontaneum, Saccharum narenga, Saccharum benghalense , and Vetiveria zizanioides . [1]
There are 79 known species of mammals in the ecoregion. Large mammals, including tiger (Panthera tigris), Indian rhinoceros (Rhinoceros unicornis), Asian elephant (Elephas maximus), wild water buffalo (Bubalus arnee), chousingha (Tetracerus quadricornis), swamp deer (Rucervus duvaucelii), and sloth bear (Melursus ursinus), once roamed the ecoregion. Habitat destruction has mostly extirpated them from the ecoregion. Small populations of tiger, Asian elephant, sloth bear, and chousingha persist in the few remaining forested areas at the foot of the Himalayas. [1]
There are over 290 species of birds, including the great Indian bustard (Ardeotis nigriceps), lesser florican (Sypheotides indicus), Indian grey hornbill (Ocyceros birostris), and Oriental pied hornbill (Anthracoceros albirostris). [1]
Wetlands along the Ganges River and its tributaries support communities of resident and migrant waterfowl, along with mugger crocodile (Crocodylus palustris) and gharial (Gavialis gangeticus). The ecoregion's large rivers are home to the endangered Ganges river dolphin (Platanista gangetica gangetica). [1]
The ecoregion is currently densely populated, and the fertile plains have largely been converted to intensive agriculture, with only a few enclaves of forest remaining.
A 2017 assessment found that 3,544 km², or 1%, of the ecoregion is in protected areas. [2] Protected areas in the ecoregion include: [1]
The Malabar Coast moist forests are a tropical moist broadleaf forest ecoregion of southwestern India.
The South Western Ghats moist deciduous forests is an ecoregion in the Western Ghats of southern India with tropical and subtropical moist broadleaf forests. This biome covers the Nilgiri Hills between elevation of 250 and 1,000 m in Kerala, Karnataka and Tamil Nadu states.
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.
Gorumara National Park is a national park in northern West Bengal, India. Located in the Dooars region of the Himalayan foothills, it is a medium-sized park with grasslands and forests. Gorumara National Park was established in 1992. It is primarily known for its population of Indian rhinoceros. The park was declared as the best among the protected areas in India by the Ministry of Environment and Forests for the year 2009.
Valmiki National Park is a tiger reserve in the West Champaran District of Bihar, India. It is the only national park in Bihar. Valmiki Tiger Reserve covers 898.45 km2 (346.89 sq mi), which is 17.4% of the total geographical area of the district. As of 2022, there were 54 tigers in the Reserve.
The Terai–Duar savanna and grasslands is a narrow lowland ecoregion at the base of the Himalayas, about 25 km (16 mi) wide, and a continuation of the Indo-Gangetic Plain in India, Nepal and Bhutan. It is colloquially called Terai in the Ganges Basin east to Nepal, then Dooars in West Bengal, Bhutan and Assam east to the Brahmaputra River. It harbours the world's tallest grasslands, which are the most threatened and rare worldwide.
The Odisha semi-evergreen forests are a tropical moist broadleaf forest ecoregion of eastern India. The ecoregion covers an area of 8,600 square kilometers (3,300 sq mi) on the coastal plain of Odisha state, bounded by the Eastern Highlands moist deciduous forests west and north-west, transitioning from the huge ecoregion Lower Gangetic Plains moist deciduous forests along the north coastland, and surrounding the smaller ecoregion Godavari-Krishna mangroves along a stretch of the south-east coast by the Bay of Bengal.
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.
The Lower Gangetic Plains moist deciduous forests is a tropical and subtropical moist broadleaf forests ecoregion of Bangladesh and India. The ecoregion covers an area of 254,100 square kilometres (98,100 sq mi), comprising most of Bangladesh and the Indian states of West Bengal, Bihar and Tripura, and extending into adjacent states of Odisha, Uttar Pradesh and a tiny part of Assam, as well as adjacent western Myanmar.

Manas National Park is a national park, Project Tiger reserve, and an elephant reserve in Assam, India. Located in the Himalayan foothills, it borders the Royal Manas National Park in Bhutan. The park is known for its rare and endangered endemic wildlife such as the Assam roofed turtle, hispid hare, golden langur and pygmy hog. Manas is also famous for its population of the wild water buffalo. Because of its exceptional biodiversity, scenery, and variety of habitats, Manas National Park is a biosphere reserve and a UNESCO World Heritage Site.
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.
The Eastern Himalayan broadleaf forests is a temperate broadleaf forest ecoregion found in the middle elevations of the eastern Himalayas, including parts of Nepal, India, Bhutan, Myanmar and China. These forests have an outstanding richness of wildlife.
The Central Indochina dry forests are a large tropical and subtropical dry broadleaf forests ecoregion in Southeast Asia.
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
The Irrawaddy moist deciduous forests is a tropical moist broadleaf forest ecoregion in central Myanmar. The ecoregion occupies the central basin of the Irrawaddy River and the lower basin of the Salween River. The ecoregion is characterized by forests of tall trees which drop their leaves in the dry season. Most of the ecoregion's forests have been converted to agriculture.
