Species Diversity Quick Facts The tropical rainforest has more species of plants and animals than any other part of the world, with a significantly fewer amount of each Plants adapt to rain by shedding water off their leaves quickly so the branches don't get weighed down and break Over 2,500 species of vines grow in the rainforest and make up 40% of the canopy leaves Trees of the same species are very seldom found growing close together which prevents mass contamination from disease or insect infestation There may be 40 to 100 different species of animals in 2.5 acres (1 hectare) of a tropical rain forest Plants: Bromeliads, Carnivorous Plants (like Pitcher Plants), Epiphytes (air plants that grow on branches high in the trees), Lianas (woody vines), Orchids, Saprophytes, Stilt / Prop Roots, Strangler Fig, Bengal Bamboo, Bougainvillea, Curare, Coconut Tree, Durian, Jambu, Kapok Tree, Mangrove Forests, Tualang Animals: Africa Forest Elephant, Bengal Tiger, Chimpanzee, Common Palm Civet or Musang, Dawn Bat, Golden Lion Tamarin, Jambu Fruit Dove, King Cobra, Kinkajou, Linn's Sloth, Orangutan, Proboscis Monkey, Red-shanked Douc Langur, Silvery Gibbon, Slender Loris, Sumatra, Rhinoceros, Toco Toucan, Vampire Bat, Wagler's Pit Viper
Important Information Temperature: The average annual temperature is 77°F. The average minimum monthly temperature is a humid 64°F. Precipitation: Tropical Rainforests can average as little as 6 feet, or as much as 30 feet, of rainfall per year. What distinguishes a true rain forest is the distribution of precipitation throughout the year—there are no dry seasons. They receive at least 4 inches per month, but usually more. If a rain forest does have dry periods, they are usually short and unpredictable. Solar Insolations (seasons): Temperature and rainfall are both high and even throughout the year, which is what classifies a tropical rainforest as such. Limiting Factor: Sunlight is a major limiting factor. Beneath the canopy, there is a low intensity of light that plants and animals must adapt to in order to survive.

The Four Layers of the Rainforest Emergent Layer- Tallest trees are the emergents, standing as high as 200 feet above the forest floor with trunks that measure up to 16 feet around. Most of these trees are broad-leaved, hardwood evergreens Much sunlight since it is the top layer of the rainforest Canopy Layer- Primary layer of the forest, forms a roof over the two lower layers Most canopy trees have smooth, oval leaves that come to a point… there are a maze of branches in this layer Many animals live in this area since food is abundant Understory Layer- Little sunshine reaches this area so the plants must grow larger leaves to reach the sunlight The plants in this area rarely grow to reach 12 feet Many animals and insects live here Forest Floor- Very dark down here, since it is the lowest layer Almost no plants grow in this area Since hardly any sun reaches the forest floor things begin to decay quickly
