Eastern Highlands moist deciduous forests
The Eastern Highlands moist deciduous forests, or East Deccan moist deciduous forests, is a tropical moist deciduous forest ecoregion of 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.

Setting
The Eastern Highlands moist deciduous forests extend from the Bay of Bengal coast in northern Andhra Pradesh and southern Orissa, across the northern portion of the Eastern Ghats range and the northeastern Deccan Plateau, to the eastern Satpura Range and the upper Narmada River valley.
The forests of the ecoregion are sustained by the moisture-bearing monsoon winds from the Bay of Bengal, which lies to the southeast. The ecoregion is bounded on the north and west by tropical dry deciduous forest ecoregions, including the Central Deccan Plateau dry deciduous forests to the southwest and west, the Narmada valley dry deciduous forests to the northwest, and the Chota Nagpur dry deciduous forests to the north and northeast. The drier Northern dry deciduous forests ecoregion, lying west of the Eastern Ghats range, is completely surrounded by the Eastern Highlands moist deciduous forests, in the rain shadow of the Ghats, which partially block the moisture-laden monsoon winds off the Bay of Bengal. The humid Orissa semi-evergreen forests ecoregion lies to the northeast in the coastal lowlands of Orissa.
Flora
The ecoregion's forests are dominated by Sal (Shorea robusta), in association with Terminalia, Adina, Toona, Syzygium, Buchanania, Cleisanthus, and Anogeissus, according to soil variations. The flora of the ecoregion shares many species with the moist forests of the Western Ghats and the Eastern Himalayas.
From the Western Ghats this includes plants like Jackfruit and several lianas such as Schefflera Vine (schefflera venulosa), Joint Fir (gnetum ula), and common rattan.
From the Eastern Himalayas this includes the peculiar Indian pepper tree and several shrubs, herbs and flowers such as Yellow Himalayan raspberry, False nettle (Boehmeria macrophylla), and Whipcord cobra lily among others.
Several globally threatened plant species are found in this ecoregion, including the two endemic plants Leucas mukerjiana and Phlebophyllum jeyporensis.

Terminalia, and especially asna trees (Indian laurel), are also common.
Bamboo, especially calcutta bamboo, is prominent in many parts of this ecoregion
Plants in common with the Western Ghats includes several types of lianas (Joint Fir).

Fauna
The ecoregion still harbours large intact areas of tropical moist deciduous forests and is therefore considered an important refuge and safe haven for healthy populations of most of the original large vertebrates associated with this habitat. Among the mammals, this includes the predators Indian tigers, wolves, dhole and sloth bear, and herbivores gaur, chousingha, blackbuck, and chinkara. The Asian elephants that once lived here, though, has been extirpated long ago.
The only endemic species found in the ecoregion is the cave-dwelling Khajuria's leaf-nosed bat.

Conservation
Approximately 25% of the original habitat remains, much of it in blocks of 5000 km² or larger. 31 protected areas, totaling 13,540 km², preserve about 4% of the ecoregion's intact habitat. The largest protected area in the ecoregion is Simlipal National Park in Odisha state.[1]
