Deciduous forests
Deciduous forests are of two kinds-- temperate and tropical.
Deciduous forests have predominantly broad-leafed trees. Temperate deciduous forests occur in areas of moderate temperature and rainfall with cold winters. Species belonging to these forests drop leaves in autumn. The deciduous forests in tropical areas shed leaves only by December (in the Northern Hemisphere) when water becomes scarce.Decidous forests

Tropical Monsoon Deciduous Forests in India:
The tropical monsoon deciduous forests are found in areas receiving annual rainfall of 100 to 200 cms in India, with a distinct dry and rainy seasons and a small range of temperature.
 They occur on the wetter western side of the Deccan Plateau, the north-eastern part of the Deccan Plateau and the lower slopes of the Himalayas, on the Siwalik Hills from Jammu in the west to West Bengal in the east.

They cover parts of Chhattisgarh, Orissa, Bihar, Jharkand, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu.

The principal trees of these forests are teak, sal, sandalwood, mahua, khair, mango, jackfruit, wattle and bamboo, semal, sisasm, myrobalan, arjun and the banyan tree. They shed their leaves for six to eight weeks during the dry season, usually from March to  May, to prevent the loss of moisture through evapo-transpiration.

Kerala's deciduous forests:
The principal specie of Kerala's deciduous forests is teak. Others include Terminalia species (such as Maruth, Kadukka and Thanni),  Lagerstroemia lanceolata (Venthekku, known as naked maiden of forest), Cassia fistula (Konna-- a picture of its flowers is used to form the tiled pattern above). These grow in fairly open forests. Their leaves are characteristically light green in contrast to dark green leaves of trees in tropical evergreen forests. They also exhibit low branching in contrast to trees of evergreen forests.


The correct spelling is deciduous, not decidous forests.
