Deciduous vs. Evergreen Trees of India: Teak, Mahua, and Jackfruit

India’s most valuable timber tree goes bare every winter. Its most popular tropical fruit tree never does. The difference is a basic ecological trait UPSC tests often.

Deciduous vs. Evergreen Trees of India

Teak

Deciduous. India’s most valuable timber tree.

Mahua

Deciduous. Flowers used for food and drink.

Jackfruit

Evergreen. Keeps its leaves year-round.

Why this matters for the exam

A 2023 UPSC prelims question tested exactly this: teak and mahua are deciduous, but jackfruit is evergreen. Only two of the three qualified.

📌 Must Know

Deciduous vs. Evergreen

The Basic Difference Deciduous trees shed all their leaves for part of the year, usually the dry season. Evergreen trees retain leaves year-round, shedding and replacing them gradually instead.
Teak Teak (Tectona grandis) is a deciduous tree, and the most economically important species of India’s tropical deciduous forests.
Mahua Mahua (Madhuca indica) is also deciduous, common across central and northern India, shedding its leaves between roughly February and April.
Jackfruit Jackfruit (Artocarpus heterophyllus) is an evergreen tree, native to India’s Western Ghats and grown widely across South and Southeast Asia.

💡 Good to Know

Timber, Food, and Forest Type

Teak’s Value Teak wood is prized for shipbuilding, furniture, and construction, thanks to its durability and natural resistance to rot and pests.
Mahua’s Uses Mahua flowers are used to make food and traditional alcoholic drinks. Its seeds yield an edible oil, making it economically important for forest-dwelling and tribal communities.
Tropical Deciduous Forests Teak and mahua both typify India’s tropical deciduous forests, found across large parts of central India, receiving moderate rainfall.
Jackfruit’s Range Jackfruit is the national fruit of Bangladesh and widely cultivated across India, prized for both its ripe fruit and its unripe form used as a vegetable.

📝 Exam Point of View

UPSC: Name the Deciduous Trees

UPSC 2023 Asked as: “Consider the following trees. How many of the above are deciduous trees?” UPSC CSP 2023, GS Paper I. Answer: only two, since jackfruit is evergreen.
UPSC 2015 Also asked as: “In India, in which one of the following types of forests is teak a dominant tree species?” UPSC CSP 2015, GS Paper I. Teak dominates tropical moist deciduous forest, not rain forest, thorn scrub, or temperate forest.
The Trap Candidates often assume any prominent Indian tree shares the same leaf habit. UPSC exploits exactly that assumption by mixing deciduous and evergreen trees in one list.

Why Leaf Habit Gets Tested

Not Just Botany Leaf-shedding habit connects directly to forest classification. India’s forest types, like tropical deciduous and tropical evergreen, are largely defined by rainfall and this exact trait.
Ecological Adaptation Shedding leaves in the dry season is a water-conservation strategy. It reduces moisture loss through transpiration when water is scarce.
Exam Angle This kind of “how many of the above” question rewards precise species-level knowledge over general familiarity with a tree’s name.

How India Classifies Its Forests

Champion & Seth (1968) India’s official forest classification sorts all forests into 6 major groups and 16 types, based on rainfall, temperature, and altitude, not just tree species.
Where Teak Fits Teak’s typical habitat, tropical moist deciduous forest, needs roughly 1,000 to 2,000 mm of annual rainfall with a 3-4 month dry season. Drier zones shift toward tropical dry deciduous forest instead.
Where Jackfruit Fits Jackfruit’s native range sits in tropical wet evergreen and semi-evergreen forest, which needs over 2,000 mm of rainfall and little to no real dry season, explaining why it never needs to shed its leaves.
Why This Matters Rainfall, not latitude or soil alone, is the main variable separating these forest types. That’s why deciduous and evergreen trees can grow just a few hundred kilometres apart in India.
