Frequently Asked Questions
What is the main difference between evergreen and deciduous forests?

Which type of natural vegetation is most common in Odisha?
Tropical Deciduous forests (both moist and dry deciduous) are the most dominant vegetation type found across Odisha.
Why are mangrove forests important for coastal areas?
Mangrove forests protect coastal regions from severe cyclones, tidal surges, and soil erosion while providing a breeding ground for marine life.
