Question

5. What are the environmental effects of decreasing the rotation time (accelerating the rate of cutting) in forests from an average of 60 years to 10 years? Compare these effects for (a) a woodland in a dry climate on a sandy soil and (b) a rain forest. 6. In a small but heavily forested nation, two plans are put forward for forest harvests. In Plan A, all the forests to be harvested are in the eastern part of the nation, while all the forests of the West are set aside as wilderness areas, parks, and nature preserves. In Plan B, small areas of forests to be harvested are distributed throughout the country, in many cases adjacent to parks, preserves, and wilderness areas. Which plan would you choose? Note that in Plan B, wilderness areas would be smaller than in Plan A 7. The smallest legally designated wilderness in the United States is Pelican Island, Florida, covering five acres. Do you think this can meet the meaning of wilderness and the intent of the Wilderness Act?

Explanation / Answer

5.As due to cutting of forest the rainfall decreases as the moisture content decreases in the air because tree gives us the required water vapour and oxygen so rainfall decreases .The other point is soil erosion increases as tree root catches the soil.

Comparision :-The dry land has already less moisture in the and due to forest loss we also loss more moisture so the land becomes more desortic but in rainy forest the erosion increases .

6.As the biosphere should be present at all the areas as it controls the rain fall of the area so we couldn't just cut the forest of the east side because that will cause the disbalance between east and west land so small harvest would be the best .

7.As pelican island and Florida has wilderness so we can say that they are well designed .This shows the clear intent of wilderness act as it says complete distribution of nature as per ecosystem .
