Abiotic factors Although rainforests and deserts are very different, they do have something in common. They both have mountains and steep canyons. Food webs usually have 5 levels of animals and plants. First, the producers are the bottom of the web, for example, the sun produces light for the grass.

No one knows exactly how many species live in the world’s tropical rainforests — estimates range from 3 to 50 million species — rainforests are the undisputed champions of biodiversity among the world’s ecosystems, containing far higher numbers of species on a per-area basis relative to sub-tropical, temperate, and …

The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers. Thick, woody vines are also found in the canopy. They climb trees in the canopy to reach for sunlight.

Tropical rainforests are home to indigenous peoples who rely on their surroundings for food, shelter, and medicines. Today very few forest people live in traditional ways; most have been displaced by outside settlers or have been forced to give up their lifestyles by governments.

The forest is alive, and it grows at a rapid speed. It is a constant battle for a small group of people to maintain some breathing room. The natives maintain a small space for their village, through constant use of pathways and common areas, but nothing is permanent, their homes quickly rot and have to be rebuilt.

A small area of land is cleared and the vegetation burned, providing a source of nutrients from the ash. For a few years the soil remains sufficiently fertile for the tribe to grow crops. When the soil’s fertility is exhausted, the tribe moves on and clears another small area of forest.

As a tribe, the Yanomami rely on the rainforest to provide for their needs both in terms of food and medicine. They also grow their own crops and will fish too. The women tend to be in charge of growing crops in gardens that they create themselves. The men’s role is to do the hunting.

Many activities contribute to this loss including subsistence activities, oil extraction, logging, mining, fires, war, commercial agriculture, cattle ranching, hydroelectric projects, pollution, hunting and poaching, the collection of fuel wood and building material, and road construction.

Indigenous groups have come together to protect the Amazon rainforest by calling for 200m hectares of the region into the world’s largest protected area. The Amazon is known as “the lungs of the planet” because the trees absorb so much carbon emissions, mitigating the effects of climate change.

As the First Peoples living in and managing our vast and abundant land for millennia, forests are fundamental to the livelihood of Indigenous Peoples. The sustainable use of forests within their traditional territories is critically important for subsistence, economic, and ceremonial practices.

It can help us anticipate the impact of climate change, withstand new diseases, restore damaged ecosystems, avoid food insecurity and safeguard traditional livelihoods.

“Indigenous tribes are really linked to biodiversity management and reductions in deforestation, and it’s because they live on the land and I think they have kind of a very keen sense of what it would mean to upset the ecosystem around them,” said Kathryn Baragwanath, a UCSD researcher and one of the study’s co-authors …

Since humans started cutting down forests, 46 percent of trees have been felled, according to a 2015 study in the journal Nature. About 17 percent of the Amazonian rainforest has been destroyed over the past 50 years, and losses recently have been on the rise.

Definition. Forests which are native to a given area.

What are the different types of forests found in India?

• Tropical Deciduous Forests. These trees have broadleafs.
• Tropical Rain Forests. These are also called equatorial rainforests.
• Montane Forests. This type of forest is found in mountain or hilly areas.
• Tropical Thorn forests. They are found in the area with very little rainfall (as little as 50cm).
• Swamp Forests.

We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.

There are three general types of forest that exist: temperate, tropical, and boreal. Experts estimate that these forests cover approximately one-third of Earth’s surface. Temperate forests are found across eastern North America and Eurasia.

Forests can be classified into three main types based on the latitudes where they are located: tropical forests; boreal forests; and temperate forests.

There are broadly three major types of forests – tropical, temperate, and boreal forests. They are classified according to latitude. Also, these major types are divided farther into more specific categories.
