Tropical Deciduous Forests
and
Thorny forests and scrubs
The tropical deciduous forest is found in tropical areas with a dry season that still has enough moisture for tree growth. Note the Asiatic lions in the photo.
Tropical Deciduous Forest
Western India
Introduction
Tropical deciduous forests are like
tropical rain forests, but have a
pronounced dry season which causes
the trees to lose their leaves. This type
of forest is found on the fringes of the
tropical rain forests. As the climate
gets drier, tropical deciduous forests
grade into savannah, and, eventually,
grasslands.
DistributionTropical deciduous forests grow in
seasonally dry areas of the tropics.
These forests occur mainly in India, the
Myanmar-Vietnam-southern coastal
China region, eastern Brazil, smaller
areas in South and Central America,
the West Indies, south-eastern Africa,
and northern Australia.
Dry
Wet
Climate
Well defined dry (winter) and wet
(summer) season
Rainfall of 70-200cm
Like in the tropical rainforest
climate, temperatures remain
high all year
Soil is richer in nutrients
than in tropical rainforest
because trees drop
down leaves and the
trees grow more
sparsely.
Moist deciduous forests are found in tropical
regions where both rainy and dry seasons
occur during the year. These forests are
different from tropical rain forests in that the
trees are not as tall and have rather thick
bark. In the first month of the dry season,
the leaves fall. New leaves sprout just
before the rainy season begins.
Dry tropical deciduous forests occur in regions that have long, severe dry seasons, such as the savannas (grasslands) of Africa. The tallest trees are shorter and more twisted than those in a temperate forest, and the bark is thicker. Some trees may store water in their trunks. During the dry season, the trees lose their leaves, and many produce flowers. Some, such as wattle trees in Australia, have adapted by producing thorns instead of many leaves.
The trees here are typically not as close
together as in the tropical rainforests,
so more light can reach the forest floor,
especially when the deciduous species
have dropped their leaves. The
availability of sunlight on the forest floor
results in dense undergrowth, which
makes walking extremely difficult.

Dry tropical forests share many of the
problems of the rainforest, in terms of
pressures for agricultural development as a
consequence of human population
pressure. Recovery of these forests after
disturbance can take even longer than that
of rainforest.
Monsoon forests are now largely logged out
in SE Asia. Dry tropical forests also heavily
logged, nearly vanished in Indonesia.

Thorny forests and scrubs
Rainfall below 70 cm.Natural vegetation - Thorny trees and bushes.Main areas are Rajasthan, Gujrat,Haryana and M.P.Acacias, Cacti, Euphorbias and palms are the main plants growing.Leaves are mostly thick and small to minimize evaporation
