Conclusion

4. 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.

Oxygen
life Survival

5. Role of Forests in Biogeochemical Cycling
Forests covers roughly 31 % of the Earth’s land surface, about 4 billion hectares.

7. Provide habitat for countless organisms
Serving as one of the most important reservoirs in carbon cycle
Major participant in biogeochemical cycles such as nitrogen, carbon and water cycle.
Provide humanity with wood for fuel, construction, paper production and many more
Help to maintain soil, air and water quality

8. Structure of Forests
Canopy: the upper level of leaves and branches defined by the majority of treetops
Woodland: wooded (treed) area in which the canopy is more open or discontinuous have openings between the trees that allow light to penetrate the ground
Floor: Ground of forest

9. Major groups of forests biomes
Boreal Forests
Temperature
Cold and have relatively dry climate with short growing season
Location
 North America, and the taiga in Europe and Asia

10. Flora
Trees such as spruce, pine, aspen, and birch dominate the landscape (which is often covered in snow), struggling through the long, cold winters in shallow soil, roots frozen.
Fauna
woodpeckers, hawks, moose, bear, weasel, lynx, fox, wolf, deer, hares, chipmunks, shrews, and bats

11. Temperate Forests Temperature
-30°C to 30°C, yearly average is 10°C, hot summers, cold winters
Location
Eastern United States, Canada, Europe, China, and Japan
Other
Temperate deciduous forests are most notable because they go through four seasons. Leaves change color in autumn, fall off in the winter, and grow back in the spring; this adaptation allows plants to survive cold winters.

12. Flora
Broadleaf trees (oaks, maples, beeches), shrubs, perennial herbs, and mosses
Fauna
squirrels, rabbits, skunks, birds, deer, mountain lion, bobcat, timber wolf, fox, and black bear

13. Tropical forests
The Tropical Rainforest is a forest occurring in tropical areas of heavy rainfall.
Temperature
Tropical rainforests can be characterized in two words: hot and wet. A typical daytime temperature any time of year in tropical rainforests is 29°C (85°F), although temperatures can be much higher. Average annual rainfall is no less than 1,680 mm.
Location
Scattered in equatorial south and Central America, Equatorial Africa, Indonesia and Southeast Asia.
These trees are evergreen because they have year round growing conditions.

14. Flora
In the tropical rainforest most trees in the rainforest have wide buttress roots. This is to support them as they grow incredibly tall (over 200ft in some cases) as there is great competition for sunlight.
Fauna
Animals, including monkeys, birds, snakes, rodents, frogs, and lizards are common in the tropical rainforest. Many of these animals and a multitude of insects never set foot on the ground.

16. Forests facilitate ecotourism through the provision of a number of recreational activities like trekking, cycling, fishing, boating, sight seeing and camping.
Forests are important income and employment generators as they stimulate a number of subsidiary industries and form a source of livelihood for many human settlements.
They are major source of lumber, fuel wood, latex and paper. They also aid in provision of edible products including foods, fruits, resins, oils, nuts, honey, vegetable, mushrooms, fungi etc.
Forests play a part in atmospheric regulation, soil conservation, reduction of sedimentation and siltation for irrigation and power generation.
Forests ease to reduce carbon dioxide level and temperature thus purifying the air. Also forests reduce the rate of surface run off of water and hence prevent floods, soil erosion and degradation of soil’s quality.

17. Promotes rainfall
Prevents soil erosion
Reduces noise pollution
Maintains the composition of the soil
Prevents Global warming
Prevents flooding
