71. Which type of forest has the maximum area in Odisha?
Tropical semi - evergreen
Tropical moist deciduous
Tropical dry deciduous
Coastal Tidal
Concept:
Tropical Deciduous Forests:-
These forests are called Monsoon Forests. Rainfall in Deciduous Forests is in the range of 70-200 cms.
A long dry season followed by a heavy rainfall season is a feature of the regions where deciduous forests are found.
Types of Deciduous Forests -
Moist Deciduous Forests
Dry Deciduous Forests
Tropical Dry Deciduous: Dry deciduous forest covers vast areas of the country, where rainfall ranges between 70 -100 cm.
On the wetter margins, it has a transition to the moist deciduous, while on the drier margins to thorn forests.
As the dry season begins, the trees shed their leaves completely and the forest appears like a vast grassland with naked trees all around.
Tendu, palas, amaltas, bel, Khair, axlewood, etc. are the common trees of these forests.
