Tropical Dry

Forest

By: Jaynee Douglas and Deja Moore

What is a Tropical Dry Forest?

• Border tropical rain forests• Tropical dry forests grow in places where

rainfall is highly seasonal rather than year-round.

• Rainfall is sufficient enough to promote growth of trees, but these tree and plant species must be able to withstand periods of low precipitation and moisture such as cactus

• Rich soils subject to erosion• Decomposition is rapid and soils are subject

to heavy leaching

More characteristics• Humans have settled in this biome

because it is a very pleasant place to live due to the warm temperatures there and because it doesn't rain too much there.

• Most of tropical dry forests are found by the equator

• Are seasonal and tropical

Climate

• The temperatures are high all year• Hard dry seasons last several months• Better developed dry season than in

the tropical rain forest• Receives about several hundreds of

centimeters of rain fall per year , the average being between 40-100

Location

• Can be found north

and south of the

equatorial forest belt

• The most known are located in: parts of Africa, South and Central America, Mexico, India, Australia, and Tropical Islands

PLANTS

Animals• Has a wide variety of wildlife from the Gray

Wolf to the African Lion• The dominant wildlife here is tigers,

monkeys, herbivores, birds, and insects.• Most animals have to do adaptations in

order to survive the dry weather since dry seasons are extremely long

• One adaptation with animals is estivation (like hibernation) they do this during the summer-time to reduce their water needs

Plants• Trees and plants must be able to survive

periods of low precipitation and moisture• Most of the trees here are deciduous • Most plant life in the dry season will drop

their leaves in order to reduce the water needs in them and to conserve what’s left of it

• In order to survive trees have thicker, more ridged, bark; deeper roots, much more variable leaves; and more types of thorns

• The single most important adaptation among plants is deciduousness

Human Impact• Deforestation: While humans are

depleting the forest vegetation is being destroyed it also disrupts the relationships and habitats that animals have

• As habitats are lost so are animals which leads to a drop in the diversity in animals

• Hunting has also negatively impacted topical dry forests, animals such as tigers have been hunted to near extinction

More Human impact• Much of the land is being cleared

because topical dry forests are the most desired places to live

• Pollution that is heavily found in tropical dry forests comes from mining, specifically gold
