Rainforest Biomes

Rainforest Biomes
The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Rainforests now cover less than 6% of Earth's land surface. A tropical rain forest has more kinds of trees than any other area in the world. About 1/4 of all the medicines we use come from rainforest plants. All tropical rain forests resemble one another in some ways. Despite these differences, each of the three largest rainforests--the American, the African, and the Asian--has a different group of animal and plant species.

Rainforests Facts Facts about Rainforests Do you know how many tropical rainforest plants have been identified as having anti-cancer properties? Or how many continents around the world contain rainforests? Cold Tempetures Updated January 11, 2009 A rainforest is a forest differentiated by high levels of precipitation - normally a minimum of at least 68-78 inches (172-198 cm) annually. Rainforests tend to have fairly mild and/or warm climates and feature the highest levels of biodiversity in the world. Additionally, tropical rainforests are considered the "lungs of the Earth" because of the high amount of photosynthesis occurring in them. Locations and Types of Rainforests Within the rainforest biome, there are two specific types of rainforest.

Preserve The Rainforest By saving the plants and trees of the rainforest you are contributing twofold – first by eliminating the continuing release of these greenhouse gases into the atmosphere and the subsequent destruction brought about by burning our most precious storage containers – the trees – and second by reversing the existing carbon dioxide emissions through the absorption of carbon by the plants and trees. Trees in the rainforest work like the lungs of the earth in reverse fashion from our own breathing. Trees absorb carbon dioxide emissions in the atmosphere and release clean oxygen. The rainforest is the Single greatest source of the air that we breathe, accounting for a full 20%. Saving the rainforest is critical to maintaining clean air and a healthy environment.

Rain Forest Threats, Rain Forest Species More than half of Earth’s rain forests have already been lost forever to the insatiable human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent. And if current deforestation rates continue, these critical habitats could disappear from the planet completely within the next hundred years. The reasons for plundering rain forests are mainly economic. Ten Amazing Rainforest Plants Our surroundings are sometimes taken for granted. Even something as unique as the rainforest is forgotten. It seems a little bit of knowledge and a shove in the right direction can get people to appreciate the environment.

Cool Trees A giant in the rainforests, the kapok tree can reach up to 200 feet in height, sometimes growing as much as 13 feet per year. Due to its extreme height, the kapok, or ceiba tree, towers over the other rainforest vegetation. The trunk can expand to nine or 10 feet in diameter. In the nooks and grooves of this huge plant live a diverse number of species including frogs, birds and bromeliads. The kapok tree is deciduous, shedding all of its leaves during the dry season. Why Save the Rain Forest? Imagine what it is like to walk through a rain forest. You pass hundreds of trees, many more than 125 feet high. You see orchids, ferns, and other exotic plants growing on tree trunks. Above, sunlight filters through the canopy of leaves, but you are walking in deep shade. Many animals live up in the canopy, while other creatures are well hidden in the thick foliage of the understory.

Rain Forest In Brazil, which houses 30 percent of the remaining tropical rain forest on Earth, more than 50,000 square miles of rain forest were lost to deforestation between 2000 and 2005. Biologists worry about the long-term consequences. Drought may be one. Some rain forests, including the Amazon, began experiencing drought in the 1990s, possibly due to deforestation and global warming. The Plants of the Rainforest A tropical greenhouse More than two thirds of the world's plant species are found in the tropical rainforests: plants that provide shelter and food for rainforest animals as well as taking part in the gas exchanges which provide much of the world's oxygen supply. Rainforest plants live in a warm humid environment that allows an enormous variation rare in more temperate climates: some like the orchids have beautiful flowers adapted to attract the profusion of forest insects.

Medical Plants Rainforest Remedies Daniel Mowrey, Ph.D. Undiscovered Riches The number of potentially useful medicinal plants growing in the world's rainforests is estimated to be in the thousands. Certainly, mankind would benefit from the application of these plants. In future years, we might witness the discovery of cures for many serious diseases in rainforest plants. But there are serious questions about how we should go about achieving these goals.

What is a Rainforest and why are they Important? - Conserve Energy Future You’ve probably heard of a rainforest before. They are tall, hot and dense forests found all around the world and serve a significant purpose in the environment. They serve as the Earth’s oldest ecological system. Although a rainforest covers only around 6% of the earth, amazingly they account for ½ of the plants and animals found! In a nutshell a rainforest is a dense jungle. As the name suggests, rainforests are the forests that receive more than 1000 mm of rainfall throughout the year are mostly found around the middle of the earth near the equator like South and Central America, Africa, Asia and Australia.
