DESTRUCTION OF RAINFOREST What is a Rainforest? : What is a Rainforest? It’s a beautiful part of the Earth.
Rainforest are very dense, warm, wet forest.
A home for lot of plants and medicines.
Also, a home for lot of animals. TYPES OF RAINFOREST AND WHERE ARE THEY FOUND? : TROPICAL RAINFOREST
TEMPRATE RAINFOREST TYPES OF RAINFOREST AND WHERE ARE THEY FOUND? TROPICAL RAINFOREST : TROPICAL RAINFOREST These rainforest are in the tropics, found near the Equator (between the Tropic of Cancer and Tropic of Capricorn) and present in South East Asia.
Tropical rainforests have been called the "Earth's lungs," although it is now known that rainforests contribute little net oxygen additions to the atmosphere through photosynthesis. TEMPERATE RAINFOREST : Temperate rainforests are in temperate regions They can be found in parts of North America, Europe, New Zealand and Australia. TEMPERATE RAINFOREST RAINFALL, TEMPERATURE AND SOIL IN RAINFOREST : RAINFALL, TEMPERATURE AND SOIL IN RAINFOREST RAINFALL: It is almost always raining in a rainforest. Rainforests get over 80 inches (2 m) of rain each year.
The rain is more evenly distributed throughout the year in a tropical rainforest (even though there is a little seasonality). In a temperate rainforest, there are wet and dry seasons. During the "dry" season, coastal fog supplies abundant moisture to the forest. TEMPERATURE : TEMPERATURE The temperature in a rainforest never freezes and never gets very hot.
The range of temperature in a tropical rainforest is usually between 75° F and 80° F (24-27° C).
Temperate rainforests rarely freeze or get over 80° F (27° C). SOIL : SOIL The soil of a tropical rainforest is only about 3-4 inches (7.8-10 cm) thick and is ancient. Thick clay lies underneath the soil. Once damaged, the soil of a tropical rainforest takes many years to recover.
Temperate rainforests have soil that is richer in nutrients, relatively young and less prone to damage. PEOPLE LIVING IN RAINFOREST : PEOPLE LIVING IN RAINFOREST There are many indigenous groups of people who have live in the tropical rainforests.
The Yanomamo tribe of the Amazon rainforests of Brazil and southern Venezuela, have lived in scattered villages in the rainforests for hundreds or thousands of years.
These tribes get their food, clothing, and housing mainly from materials they obtain in the forests.
Forest people are mostly hunter-gatherers; they get their food by hunting for meat (and fishing for fish) and gathering edible plants, like starchy roots and fruit. LAYERS OF RAINFOREST : LAYERS OF RAINFOREST EMERGENT LAYER
UNDER STORY LAYER
FOREST FLOOR LAYER Emergent Layer : Emergent Layer This is the top layer in the Rain Forest.
The trees in the emergent layer tower over everything, averaging around 270 feet in the air. The trees receive direct sunlight.
Birds, Eagles, Hawks live among the branches. Canopy Layer : Canopy Layer Just under the Emergent layer, fanning out and making a canopy over the lower layers.
The leaves in this layer acts as a source of power for the forest by converting sunlight to energy through photosynthesis.
Animals that live here are macaws, monkeys, cuckoos, and lizards. Glad for the warmth of the sun. Most animals in the Rain Forest live in this layer. Under story Layer : Under story Layer The under story layer is a very damp and hot place to live.
It is located in the lower branches and tree trunks of trees in the rainforest. Birds and monkeys travel through this area when looking for food.
Small plants and flowers also grow in this layer.
The animals that live here include bees, snakes and frogs. Forest Floor Layer : Forest Floor Layer - The forest floor is a very warm and humid place to live.
- Hardly any sunlight reaches this area so many plants which only needs less amount of light grow here such as ferns and mosses. - Animals like tapirs, jaguars, ants, elephants live here. Layers of the tropical rainforest : Layers of the tropical rainforest * Tall Trees- 150ft tall; branches at the highest level; act like an umbrella * VERY THICK! Less than 2% of sunlight reaches the next layer; animals live here * Trees grow to about 12ft. Home of leopards, snakes, and insects Shrub layer * Grow shorter than 12 ft * No growth, no sunlight & 100% humidity FLORA AND FAUNA : FLORA AND FAUNA Slide 18: More than half of the world's species of plants and animals are found in the rainforest.
Rainforests support a very broad array of fauna including mammals, reptiles, birds, and invertebrates. Mammals may include primates, felids, and other families.
Reptiles include snakes, turtles, chameleons, and other families while birds include such families as vangidae and Cuculidae. Dozens of families of invertebrates are found in rainforests. Fungi are also very common in rainforest areas as they can feed on the decomposing remains of plant and animal life.
These species are rapidly disappearing due to deforestation, habitat loss, and biochemical releases into the atmosphere IMPORTANCE OF RAINFOREST : IMPORTANCE OF RAINFOREST - Tropical rainforests cover about 7% of the Earth's surface and are very important to the Earth's ecosystem.
- The rainforests recycle and clean water.
Tropical rainforest trees and plants also remove carbon dioxide from the atmosphere and store it in their roots, stems, leaves, and branches.
- Rainforests affect the greenhouse effect, which traps heat inside the Earth's atmosphere. Slide 20: - Foods from rainforests around the world include cashew nuts, Brazil nuts, Macadamia nuts, bananas, plantains, pineapple, cucumber, cocoa (chocolate), coffee, tea, avocados, papaya, guava, mango, cassava (a starchy root), tapioca, yams, sweet potato, okra, cinnamon, vanilla, nutmeg, mace, ginger, cayenne pepper, cloves, oranges, grapefruit, lemons, limes, passion fruit, peanuts, rice, sugar cane, and coconuts (mostly from coastal areas). DESTRUCTION OF RAINFOREST : DESTRUCTION OF RAINFOREST Slash and Burn:
Cutting down the forest for farms, roads, & other development. The trees are then burned Slide 22: Bio Diversity: Many types of animals, insects, & plant life
Deforestation: Cutting down large areas of forest Remaining rainforests : Remaining rainforests Dark Green Areas= only remaining rainforest left INTERESTING FACTS ON THE RAINFOREST : INTERESTING FACTS ON THE RAINFOREST An area of a rainforest the size of a football field is being destroyed each second.
Giant bamboo plants can grow up to 9 inches a day.
The trees of a tropical rainforest are so densely packed that rain falling on the canopy can take as long as 10 minutes to reach the ground.
Some rainforest monkeys are omnivores, eating both animals and plants.
More than 2,000 different species of butterflies are found in the rainforests of South America.
The forests of Central Africa are home to more than 8,000 different species of plants. INTERESTING FACTS ON THE RAINFOREST : INTERESTING FACTS ON THE RAINFOREST 80% of the flowers in the Australian rainforests are not found anywhere else in the world.
