THE TROPICAL RAINFOREST ANDDEFORESTATION
Diagram of the Tropical Rainforest:
Parts of the Tropical Rainforest:
1. Emergent Layer –These are the giant trees that have
huge mushroom-shaped crowns.–They enjoy the greatest amount of
sunlight, but MUST endure high temperatures with low humidity, and strong winds.
Parts of the Tropical Rainforest(cont.) :
2. Canopy Layer–These trees form a constricted, continuous
canopy 60-90 feet above the ground.–The branches are often covered with other
plants and connected with vines. –The canopy is an abode to 90% of the
organisms found in the rainforest.
Parts of the Tropical Rainforest(cont.) :
3. Understory –Receives only 2-15% of the sunlight that the
canopy attracts–Many popular house plants come from this
layer
Parts of the Tropical Rainforest(cont.) :
4. Forest Floor–Very little grows except plants that adapt to
very low light– It receives less than 2% of the sunlight–Fallen leaves, seeds, fruits, and branches
decompose extremely quickly on the floor
Location:
• Covers 6% of the Earth’s surface • Located around the belt of the equator• Areas include:
– Amazon Basin – Congo and lower regions of Africa– Southeast Asia – Central America– The Queensland Coast–Madagascar
Climate:• Average temperature is more than 20 degrees
Celsius• Temperature ranges from 20-25 degrees
Celsius • Has little variation in day length throughout
the year• Has 250+ cm of rain during the year
Biological Diversity:
• Refers to all of the different kinds of life on Earth
• 50% of all species are found in the tropical rainforests
• Has provided many medicines to treat diseases
Animals:
• A wide variety that adapt to their surroundings
• Use coloring to alert predators of their poison • Camouflage is also used to avoid predators
The Capybara: Hydrochaeris hydrochaeris
• Spends much time in water • Capybaras feed on plant material, including
aquatic plants• Live in family groups • Are active at dawn and dusk
The Chimpanzee:Pan troglodytes
• Has a wide range of sounds and gestures for communication
• They eat plant material (fruit, nuts, leaves, shoots, bark), eggs, and insects
• They climb well but spend most of the time on the ground
Crested Guan Penelope purpurascens
• Primarily tree-living birds• They eat fruits and seeds• While in flight, the bird begins to beat its
wings at twice the normal speed, creating a whirring sound
Vegetation:
• Consists of the plants, jungle trees, and flowers
• Often interacts with animals, birds, and insects• Most leaves have pointed ends so the water
can drip off
Coccoloba:Coccoloba pubescens
• Referred to as “Eve’s Umbrella”
• Can grow up to 80 feet
• Has large, veined ornamental leaves
Peacock Plant:Calathea makoyana
• Well adapted to the low light of the forest floor
• The leaves of the plant fold up at night• It has striking markings on the upper surface
of the leaf
Ylang-Ylang:Cananga odorata
• Located in southeast Asia
• Can grow up to 80 feet• Leaves are used for some of the world’s most
expensive perfumes
Deforestation:
• The removal of a forests where the land is changed to a nonforest use
• Reasons– Farmland– Logging– Road building– Grazing lands– Paper
Deforestation (cont.):
• Population growth intensifies deforestation
• Displaces people of the forest
• We lose important knowledge of plants and animals
Deforestation and the Rainforest:
• Removes vegetation
• 1 ½ acres of land are lost every second
• Deforestation is used for logging, creating grazing land, and firewood
How can WE stop deforestation?:
• Advocating and participating in recycling programs
• Use less paper
• Implementing preventative legislation
• Eat less meat
• REDUCE, REUSE, RECYCLE!!!!!
Thank you for your time
