The document discusses the value and uses of forests in the Philippines. It describes forests as areas where plants and animals live together in close association. Forests have intangible ecological and cultural values as well as tangible material values. Forests help regulate water cycles by increasing rainfall, storing water, and controlling water flow. This prevents issues like soil erosion, floods, droughts, and damage from typhoons. Forests also promote agricultural production by improving soil fertility and protecting crops from pests. They help maintain a healthy climate and act as pollution regulators. Forest trees can be used commercially to supply raw materials for wood industries and provide income opportunities.

1. Philippine
Forest
Group 13

2. TERRESTRIAL ECOSYSTEM
IN THE PHILIPPINES
FOREST - is a partnership of trees,
shrubs, vines, herbs, and animal life.
It is an area of land where plant and
animal life live together in close
association, bound by specific and
recognizable patterns of
interdependence.

3. FOREST VALUE AND THEIR
USES
Intangible values of the forest are
those which cannot be quantified in
material terms but are essential for
maintaining life support systems and
for sustaining environmental
stability.
Examples:

4. * Ecological Values
* Cultural/Aesthetic Values
* Moral or Ethical Values
Tangible Values of the forest can
be realized either through extractive
use or non-extractive use. Harvesting
forest products can be profitable for
the local communities.
* Material Values

5. Help regulate Nature’s water
cycle - A forest can keep the natural
water cycle in balance by:
* Increasing the amount of rainfall in
its area.
* Storing the rainwater afterwards.
* Controlling the flow of this water to
surrounding lowlands.
* Water source.

6. WHAT TYPE OF ECOLOGICAL
DAMAGE IS THUS
PREVENTED BY FOREST?
Soil Erosion barrier
Floods and tidal wave barrier
Droughts

7. Promote and protect
agricultural production. A forest
can directly benefit agriculture in at
least two ways:
By improving soil fertility
By protecting crops against common
pests
Reduce destruction from
typhoon

8. Help maintain a wholesome
climate and act as soil stabilizer
Help cut down air and noise
pollution
Pollution regulator
Source of medicine and food
Natural source of plant and
animal strains resistant to pest

9. Economic Assets, because they:
Supply the raw materials for our wood
and forest-based industries. Among
the other useful products derived from
forest are:
 Exudents, Tannins, Dye, Bark
 Medicine from leaves and bark

10. Account for substantial foreign
exchange earned from abroad.
Provide income and employment
opportunities and contribute in other
ways to overall economic development.

11. FOREST TREES
Tree - is a woody perennial plant
with one stem or trunk which
develops many branches. Tress
commonly grow to more that 10 feet,
some reach hundreds of feet high.
Trees can live for many years.

12. Forest cover - includes all forested
areas without limitation in size or tree
species. Aside from natural forest,
forest cover also includes man-made
forest and small wooded areas.

13. Commercial Forest - is that in
which is commercially important.
This means that a sizeable amount of
forest resources are ready to be in the
wood based industries.
