The Khathiar–Gir dry deciduous forests (also Kathiarbar-Gir or Kathiawar-Gir) 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.^[3]

Landscape

The Khathiar–Gir dry deciduous forests include the Aravalli Range, the high point of which is Mount Abu with an elevation of 1,721 m (5,646 feet), and a small part of the Northwestern thorn scrub forests in the west. In the west is the Kathiawar Peninsula and the strip of western Rajasthan between the Aravalli Range and Thar Desert. To the northwest, the Kathiawar-Gir dry deciduous forests transit to the Upper Gangetic Plains moist deciduous forests. To the southeast lies the Narmada Valley dry deciduous forests, of the Vindhya Range, and the Narmada River Valley. The ecoregion also borders the North Western Ghats moist deciduous forests in southeastern Gujarat.^{[citation needed]}

The ecoregion has a tropical monsoon climate, with most of its 550 to 700 mm average annual rainfall during the June–September southwest monsoon and little for the remaining months of the year, while temperatures often exceed 40 °C. Higher elevations of the Aravallis stay cooler, and the windward slopes (generally southeast-facing) receive higher rainfall. This results in a dry landscape of thorny scrub, bare trees and rocks.^[3]

Flora

The composition of the ecoregion's forests varies with moisture and soil. They have a three-storied structure, with the top story reaching 15 to 25 m (49 to 82 ft). Arid areas are dominated by Anogeissus pendula growing in association with khair, especially on the quartzite ridges and gneiss hillocks of the Aravalli Range. Less arid areas are dominated by teak (Tectona grandis), bael (Aegle marmelos), Boswellia serrata, Desmodium oojeinense, Diospyros species, silk-cotton tree, Sterculia urens, Phyllanthus emblica, Dalbergia paniculata, and Terminalia elliptica. Mount Abu is covered in dry deciduous forest with conifers at the highest elevations. Thorn scrub forests, characterized by Euphorbia caducifolia, Maytenus emarginata, Acacia senegal, Commiphora mukul, Wrightia tinctoria, Flueggea leucopyrus, Grewia species, occur on rocky Aravalli hillsides and in degraded areas. The endemic species Dicliptera abuensis, Strobilanthes halbergii, and Veronica anagallis also grow in these areas. Date palms (Phoenix sylvestris) and fig trees (Ficus racemosa) grow near rivers and streams of the hills.^[3]

Fauna

Bird species include the:^[3]

• endangered great Indian bustard (Ardeotis nigriceps)
• lesser florican (Eupodotis indica)
• near-endemic white-naped tit (Parus nuchalis), which inhabits the thorny scrub areas of the ecoregion.

The protected areas of this region are also home to 80 mammal species including^[3]

• jungle cat (Felis chaus), Asiatic wildcat (Felis silvestris ornata) and rusty-spotted cat (Prionailurus rubiginosus).^[4]
• golden jackal (Canis aureus)^[5]
• Bengal tiger (Panthera tigris tigris) in the eastern part of this ecoregion^[6]
• Asiatic lion (Panthera leo leo) in Gir National Park and surrounding areas in Kathiawar Peninsula^[7]

Threats to biodiversity

The human population in the region is growing, and wildlife habitats have mostly been removed or degraded due to collection of firewood and timber, and use as grazing land for livestock.^{[citation needed]}
