2. • within the latitudes 28 degrees north or
south of the equator (in the equatorial
zone between the Tropic of
Cancer and Tropic of Capricorn).
• An average of 50 to 260 inches (125 to
660 cm.) of rain falls yearly.
• Temperature-higher than 93 °F (34 °C) or
drops below 68 °F (20 °C)
• Humidity- between 77 and 88%;
3. • Covered less than 6% of the Earth’s land
surface
• 50% of animals and plants live
• Produce 40% of Earth’s oxygen
• Two-thirds of all flowering plants can be
found in rainforests.
• A single hectare 42,000 different species
of insect, up to 807 trees of 313 species
and 1,500 species of higher plants.
7. Lowland equatorial evergreen
rain forests
• forests which receive high rainfall (more than
2000 mm, or 80 inches, annually) throughout
the year
• Occurs at the belt of the equator
8. Moist deciduous and semi-
evergreen seasonal forests
• high overall rainfall with a warm summer
• wet season and a cooler winter dry season
• Some trees shed off their leaves on winter
season
9. Montane rain forests
• cloud forests
• Found in cooler-climate mountain areas
• Latitude is between 1500 to 3300 m
12. Forest floor
• Forest Floor
– bottom-most layer
– receives only 2% of the sunlight
– Low vegetation-low sunlight penetration
– contains decaying plant, animal matter and fungi
– Several species of reptiles, amphibians and insects
– Also some large mammals
13. Understory
• Lies between the canopy and the forest
floor
• home to a number of birds, small
mammals, insects, reptiles, and predators
• about 5% of sunlight breaches the canopy
to arrive at the understory causing true
understory plants to seldom grow to 3 m
(10 feet)
• plants have broad leaves
14. Canopy
• primary layer of the forest
• contains the majority of the largest trees,
typically 30–45 m in height
• Tall, broad-leaved evergreen trees
• Supports rich flora and diverse fauna
15. Emergents
• contains a small number of very large
trees, called emergents
• reaching heights of 45–55 m
• few species will grow to 70–80 m tall
• unique faunal species inhabit this
layer(crowned eagle, king colobus, and
large flying fox
