Social forestry is

  1. Planting of different kinds of trees in the same area

  2. Greening of hills with the efforts of common men

  3. Raising trees on common village lands and other vacant areas of fodder, minor timber and fire wood

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Social forestry is management and protection of trees. It includes planting trees in barren lands and deforested lands for social, environmental and rural development. Basically social forestry is an approach for conservation of forests. It involves planting tress on unused land. Afforestation can promote development of rural areas as such areas are dependent on fuel wood which can be obtained from natural sources only. To meet the increasing demand of fuel wood over time, afforestation and proper management of trees is necessary.
Hence, none of the given options is correct for social forestry.
So, the correct answer is 'None of the above'

Which forest is known for large scale lumbering?

  1. Equatorial forests

  2. Mixed forests

  3. Coniferous forests

  4. Monsoon forests
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Lumbering refers to cutting and transporting the cut trees for economic and industrial use. Coniferous forests are most suitable for lumbering as they are softwood trees which are easy to cut. Also, they have long straight logs of wood fit for economic uses.
  • Equatorial, mixed and monsoon forests are also used for economic purposes, but to a little extent only as compared with coniferous forests
  • Hence option C is correct.

The  wood produced by gymnosperms is commercially known as

  1. hardwood

  2. sapwood

  3. logwood

  4. softwood
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
 Wood is secondary xylem consisting largely of dead cells involved in the transport of water and minerals as well as support. Plants grow in length because of the elongation of cells produced by terminal (apical) meristem. Most of the cells formed by meristems mature to form epidermis, general matrix tissue (parenchyma), and primary xylem and phloem. In herbaceous plants all of the vascular tissue is produced by apical meristems. In plants that subsequently become woody, a cambium layer forms between the primary xylem and phloem cells. The cambium is a lateral (expanding in width) meristem, capable of dividing to produce additional xylem toward the inside of the stem and additional phloem to the outside. Gymnosperms (softwood) are composed primarily of tracheids, long cells that conduct water primarily through openings in their side walls. Gymnosperms contain fewer kinds of cells than does angiosperm wood, and tends to be comparatively uniform.
So the correct option is 'softwood'.
