Wind is an important factor in this world. This natural phenomenon is responsible for many important processes occurring on this planet. One example is pollination which depends on wind for the transfer of pollen grains. This presentation is basically for you people to get well why is wind necessary? Read and explore!

1. WIND AS AN
ECOLOGICAL FACTOR

2. AREAS TO BE COVERED
What is wind?
Ecological effects of wind
Importance of wind

3. WIND
• Moving air is called wind. It is created by
difference in pressure in our atmosphere.
• Winds are commonly classified by following
things:
• Their spatial scale.
• Their speed.
• The types of forces that causes them.
• The regions in which they occur.
• Their effect.
• Strongest winds occur on Neptune and Saturn.
• There are two types of winds that we
encounter:
• Squalls
• Gust

4. WIND AS AN ECOLOGICAL
FACTOR
• Wind is an important ecological factor that affects
almost every aspect of plant life. Wind has long
been regarded as an important ecological factor in
forests owing to the dramatic damage hurricanes
can wreak. However, the long-term wind regime of a
site also exerts a strong influence on the growth of
trees.

5. EFFECT OF WIND ON PLANTS
• Carbon dioxide Replenishment:
• CO2 replenishment is a process by which wind
helps to deliver carbon dioxide to plant leaves,
where it is used in the process of photosynthesis to
produce energy and oxygen. Wind can help to
circulate air around plants, bringing fresh CO2 to the
leaves and removing the oxygen produced by
photosynthesis.
• Cooling:
• The bounded layer accumulates heat by conduction
over epidermis. Wind thins this layer causing cooling
of leaves.

6. CONT…
• Desiccation:
• Air in motion causes evaporation rapidly thus
increasing rate of transpiration. This results in
desiccation because of removal of water from the
tissues killing the leaves and twigs.
• Dwarfing:
• Turgidity helps the maturing cells of plant to grow to
normal sizes. The plants growing under influence of
drying winds never attain turgidity. As a result all
organs are dwarfed.

7. CONT…
• Lodging:
• It is a form of injury caused by violent wind in which
crop plants are flattened against the ground.

8. CONT…
• Breakage:
• Wind promotes breakage in plants.
• Trees with soft and brittle wood are more
susceptible to breakage. High wind uproots the
trees.
• Single or group of trees that are uprooted in a forest
are termed as wind falls or wind throws.

9. CONT…
• Deformation:
• When developing shoots are subjected to strong
wind pressure from a constant direction, the form
and the position of the shoot may become
permanently altered.
• This is called deformation.

10. ANEMOMETER
• Wind is measured by anemometer.

11. IMPORTANCE OF WIND
• Seed Dispersal:
• Wind plays a crucial role in the dispersal of seeds.
• Many plants rely on wind to carry their seeds to new
locations, which helps to increase the genetic
diversity of plant populations.

12. CONT…
• Wind Pollination:
• In cool and cold climates, the vast majority of trees ,
shrubs and herbs are wind pollinated.

13. CONT…
• Weather Patterns:
• Wind is a major factor in the formation of weather
patterns, which can have a significant impact on the
ecology of an area.
• Wind can help to distribute moisture and heat.

14. CONT…
• Migration:
• Wind is an important factor in the migration of some
animal species, such as birds and insects.
• These animals use the wind to navigate and travel
long distances.
