Forests

  1. 1. • The forest is a complex ecosystem consisting mainly of trees that buffer the earth and support a myriad of life forms. The trees help create a special environment which, in turn, affects the kinds of animals and plants that can exist in the forest. Trees are an important component of the environment. They clean the air, cool it on hot days, conserve heat at night, and act as excellent sound absorbers.
  2. 2. Occupying almost all parts of the country, the great forestbelts are divided into distinct types:1) primary or virgin forests in lowlands, like mangrove, dipterocarp, and molave forests molave forest mangrove forest
  3. 3. 2) Secondary forests- developed from virgin forests through succession by illegal logging or the kaingan system, the system in setting the forest on fire for cropping.3) Grasslands and open country- developed from and to secondary forests4) Parang vegetation- grasslands with patches of secondary forest tree species5) Bamboo thickets6) Cultivated fields
  4. 4.  Forests are often misused by people. Immature trees are cut down ruthlessly, destroying living organisms and standing timber, and consuming the seeds of young trees. And fires, as they destroy trees, cause soil erosion and floods in the lower areas.
  5. 5.  In the Philippines, setting the forest on fire in preparation for cropping is a practice known as kaingan. Forest fires are also caused by arsonists, debris burners, smokers and irresponsible campers.
  6. 6.  Indiscriminate logging is another way by which humans mismanage our forests. So many trees are cut down that reforestation can not make up for the loss.
  7. 7. • Natural factors may also bring down forests pests, grazing and gnawing animals, lightning that may cause fires, and calamities like storms or strong winds.
  8. 8. Lumber- Raw lumber has been one of Philippines’ major exports. The apitong, tanguile, guijo, and narra forests supply most of today’s construction lumber. apitong tree narra tree
  9. 9.  Paper- Paper is produced from pulpwood such as pine.Distillation products- Examples of these are wood, alcohol, acetic acid, lampblack, paints and varnishes, and charcoal. Other distillation products can also be secured from sugarcane, coconut, and nipa palms..
