lesson -forest (post -3)

Hello boys.

At the end of the lesson you will be able to:

• Describe the different layers in a forest.
• List down the ways in which the forests helps us.
• Relate SDGs (Sustainable Development Goals) to the Lesson. SDG 13: CLIMATE ACTION; and SDG 15: LIFE ON LAND

A REMINDER:the text in orange is to viewed by clicking on it.

LAYERS IN THE FORESTS: To understand it better click on the below link and watch the video.

If you pay attention to the video the different layers in the forest are possible due to the different shapes and sizes of the trees. What do you think provides structure to the tree.
It is the crown. 

The branchy part of a tree above the stem is known as the CROWN of the tree.

The different types and sizes of crowns make different horizontal layers in the forest. 

These horizontal layers are following:

EMERGENT LAYER	The tallest trees are the emergents, towering as much 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. Sunlight is plentiful up here.  Animals found are eagles, monkeys, bats and butterflies.
CANOPY LAYER	This is the primary layer of the forest and forms a roof over the two remaining layers.   Most canopy trees have smooth, oval leaves that come to a point. It's a maze of leaves and branches.  Many animals live in this area since food is abundant.   Those animals include: snakes, toucans and tree frogs.
UNDERSTOREY (UNDERGROWTH) LAYER	Little sunshine reaches this area so the plants have to grow larger leaves to reach the sunlight.   The plants in this area seldom grow to 12 feet.  Many animals live here including jaguars, red-eyed tree frogs and leopards.  There is a large concentration of insects here.
FOREST FLOOR	It's very dark down here.  Almost no plants grow in this area, as a result.  Since hardly any sun reaches the forest floor things begin to decay quickly.  A leaf that might take one year to decompose in a regular climate will disappear in  6 weeks.   Giant anteaters live in this layer.

Let us recall what we have completed till now.

Hope this was a good reminder.

Let us now look at "Why Forests are important?"

We must not forget that forests are considered as the "Lungs" of the Planet. They are the most useful renewable resource for us given by the nature. Refer to the textbook Page no. 268 for all The Major Benefits of a Forest.
