This ppt is about forest.

1. Forest
The Forests are the Flags of Nature

2. Introduction
What is Forest :
The word forest broadly describes an area that has a large number of
trees. 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.

3. Types of Forest
1. Tropical Forest
a) Moist Tropical
b) Dry Tropical
2. Temperate Forest
3. Alpine Forest

4. Tropical Forest
These are typical rain forests which grow in those areas where the
annual rainfall exceeds 250 cm, the annual temperature is about 25°-
27°C the average annual humidity exceeds 77 per cent and the dry
season is distinctly short.
Tropical forests (a.k.a. jungle) are forested landscapes in tropical
regions. Tropical rainforests are located around and near the equator,
therefore having what is called an equatorial climate characterized by
three major climatic parameters: temperature, rainfall, and dry season
intensity.

5. Moist Tropical Forest
Tropical moist forests are located in Latin America, Africa, and
southeastern Asia within 23.5 °N or S of the equator where high rainfall
and temperature conditions are found. More than half of TMF are found
in Latin America. The largest remaining area is in the northern half of
South America with smaller areas in Central America and the Carribean.
In Asia, much of Papau New Guineau, the Philippines, Indonesia,
Malaysia, and Singapore were covered by forests, although much has
already been cleared by humans. While much of Africa is savannah,
significant portions of Central Africa and Madagascar were once covered
with forest.

6. Dry Tropical Forest
Tropical dry forests (TDFs) occur in dryland environments, which are
characterized by prolonged periods of dry months. They experience
distinct seasonality and high inter-annual variability in climatic variables,
particularly rainfall. Despite the enormous ecological and livelihood
importance of TDFs, these forests are highly threatened by global changes.
So far, they have received far less attention from research and
development interventions as compared to the humid tropical forests.
Their significance is still overlooked in many countries’ national policies.
Current modeling frameworks show that drought, precipitation, and
temperature are highlighted as strong drivers of tree growth and/or
mortality in these forests. Well-valued and sustainably managed TDFs
have the potential to contribute to climate change adaptation and
mitigation, buffer against erosion and desertification, and contribute to
economic development, food security, and poverty alleviation.

7. Temperate Forest
A temperate forest is a forest found between the tropical and boreal
regions, located in the temperate zone. It is the second largest biome on
our planet, covering 25% of the world's forest area, only behind the
boreal forest, which covers about 33%.

8. Temperate forests are found in eastern North America, northeastern Asia,
and central and western Europe. In North America, the Eastern Deciduous
Forest stretches from Florida to Maine along the east coast and as far
west as Texas and Minnesota.
What are temperate forests known for?
Temperate deciduous forests are most notable because they go
through four seasons: Winter, Spring, Summer, and Fall. Leaves change
color (or senesce) in autumn, fall off in the winter, and grow back in the
spring; this adaptation allows plants to survive cold winters.

9. Alpine Forest
Alpine forests are grasslands that begin at elevations above 3000 m and
grow to the region immediately below the snowline. Alpine forests are
mostly found in mountainous areas.
What are the features of alpine forest?
They include perennial grasses, sedges, Forbes, cushion plants,
mosses, and lichens. Low temperatures, dryness, UV radiation, wind,
drought, poor nutritional soil, and a short growing season are among the
factors that Alpine plants have adapted to. These forests can be found at
elevations ranging from 2800m to 4000m.

10. Where is the alpine forest?
Alpine biomes are found in mountain regions worldwide, including
the Andes, Alps, and Rocky Mountains. The alpine biome usually lies
between an altitude of about 10,000 feet (3,000 meters), and the place
where the snow line of a mountain begins.
The Alpine region covers a territory of approximately 190 700 km² and
encompasses eight European countries: Austria, France, Germany, Italy,
Liechtenstein, Monaco, Slovenia and Switzerland

11. Importance of forest
Forests provide us with shelter, livelihoods, water, food and fuel security.
All these activities directly or indirectly involve forests. Some are easy to
figure out - fruits, paper and wood from trees, and so on.

12. What is the importance of forest in environment?
Forests cover about a third of the earth's land area and are essential
to the health of our environment. For example, trees and forests absorb
and store much of the carbon dioxide that otherwise would be
contributing to climate change. Forests are home to about 80 percent of
remaining terrestrial biodiversity.
Below are 9 reasons why forests are important and why should we
protect forests from getting axed.
1. Supports Ecosystems and Habitats
2. Protects Watershed Areas
3. Supports Biodiversity
4. Purifies the Air
5. Stabilize Climate
6. Enrich the Soil
7. Regulates the Water Cycle
8. Medicinal Value
9. Economic Significance

14. Conservation
What is conservation of forest answer?
Conservation of forest is the practice of planting more trees and
maintaining the forested areas for the sustainability for future
generations. Forests are an important natural resource and are beneficial
to humans in several ways.
Conservation is the act of protecting Earth's natural resources for current
and future generations.

16. The forests can be conserved in the following manner:
1. Introducing afforestation programs.
2. Controlling forest fires.
3. Proper utilization of forest resources.
4. Proper care should be taken to protect the forests from pests and
diseases.
Why is conservation of forest is important?
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.
