Khathiar-Gir dry deciduous forests


The Khathiar-Gir dry deciduous forests is a mostly arid ecoregion in northwestern India that stretches over 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.

Landscape

The Khathiar-Gir dry deciduous forests include the Aravalli Range, the high point of which is Mount Abu with an elevation of, 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.
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 receive higher rainfall. This results in a dry landscape of thorny scrub, bare trees and rocks.

Flora

The composition of the ecoregion's forests varies with moisture and soils. They have a three-storied structure, with the top story reaching. 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, bael, 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 and fig trees grow near rivers and streams of the hills.
