This document provides an overview of physical forestry resources. It begins by defining what a forest is as a community of trees, shrubs, herbs and other plants that cover a considerable area. It then discusses the different types of forests found around the world, including tropical evergreen forests and mangrove forests. The document outlines the structure and importance of forests, noting they regulate temperature, prevent soil erosion, and provide habitat for wildlife. It also discusses threats to forests like deforestation and provides suggestions for forest conservation and ways individuals can help protect forests.

3. Revision ExerciseOk students, tell me, what do you remember “resources” to be?

4. How about physical resources?Very good! What two categories are physical resources classified into?

5. Good! Tell me now, what is the difference between renewable and non-renewable resources? Very Good!

6. FORESTToday we will look at a very precious but delicate resource – the forest. This resource regulates the world’s temperature.The forest is said to be the “lungs of the earth”. What do you think this means?The world’s environment owes much of its state of health to the presence of forests. So too does human survival and welfare.

7. A forest is a community of trees, shrubs, herbs, and associated plants and organisms that cover a considerable area that use oxygen, water and soil nutrients as the community attains maturity and reproduces itself. WHAT IS A FOREST?

8. TYPES OF FORESTThere are different types of forests which can be seen in different parts of the world.

9. TYPES OF FORESTThough they may be different, they generallyperform the same ecological functions. These types of forests are:

10. 1. TROPICAL EVER GREEN FORESTS

11. 2. TROPICAL DECIDUOUS FORESTTrees that shed leaves annually

13. MANGROOVE FORESTS

14. STRUCTURE OF THE FOREST

15. IMPORTANCE OF FORESTSDry hay orStraw etc. used as animal food.1.They provide raw materials for certain industry. 2. They provide food, fodder, fuel, fertilizer and fibre.3. They prevent soil erosion and preserve the fertility of the soil.4. They provide moisture and lower the temperature.

16. IMPORTANCE OF FORESTSThey are the home for many animals and birds, thus , they preserve the biodiversity.They maintain the ecological balance. They provide medicinal value resulting in the making of many medicinal drugs.Forests also help to alleviate psychological stress arising from the trials of modern society.

17. IMPORTANCE OF FORESTS9. They provide the opportunity for relaxation and meditation – can lead to the development of eco-tourism.

18. Habitats of the ForestsThere are many creatures that depend on the forest for their survival. Should this precious habitat be destroyed, they will become extinct for they will not be able to survive anywhere else.

19. Habitats of the ForestsWILD LIFE - means the native animals of a regionENDANGERED SPECIES -These are the species, which are in danger of extinction and which may not survive if the adverse factors continue to rotate.VULNERABLE SPECIES - The species likely to move into the endangered category in the near future if the causal adverse factors continue to operate.

20. Habitats of the ForestsRARE SPECIES - These are the species with small population in the world and are at risk.THREATENED SPECIES - These are Species, which are in any one of the Endangered, Vulnerable, Rare Species categories.

21. THREATENED REPTILES, BIRDS & MAMMALS IN JAMAICA

22. REASONS FOR DEPLETION OF WILDLIFEAbsence of shelter to wild animals.DeforestationDestruction of wild plants which affects the survival of wild animalsPollution

23. Why is it necessary to conserve Wild Life?The wild life helps us in maintaining balance of nature. It can increase our foreign exchange if linked with tourism. The preservation of wild life helps to make their study easy.The wild life of the Caribbean is our cultural asset and had deep rooted effect on Caribbean art, sculpture and religion.

25. Wow! What a mouthful!Let’s now look at theROLE OF THE FOREST

26. Promotes rainfall

27. Prevents soil erosion

28. Prevents flooding

29. Maintains the composition of the atmosphere

30. Reduces noise pollution Acts as a wind barrier from heavy winds

31. Provides medicinal remedies

32. Recreation

33. Lumber for the construction industryAll these benefits will be of no effect if we do not care for the trees in the forests.To care for the forests, we must identify what are the causes of its destruction.
