Consider the following statements. 1. Soil erosion increases with a decrease in vegetation cover. 2. Only anthropogenic sources are responsible for soil erosion. Which of the following is/are correct? Correct Answer Only 1

The correct answer is option 1.

  • The potential for soil erosion increases if the soil has no or very little vegetative cover of plants and/or crop residues. Hence, statement 1 is correct.
  • Soil erosion is caused by both natural and anthropogenic factors that affects all landforms. Hence, statement 2 is NOT correct.
  • Plant and residue cover protects the soil from raindrop impact and splash, tends to slow down the movement of runoff water, and allows excess surface water to infiltrate.
  • The erosion-reducing effectiveness of plant and/or crop residues depends on the type, extent, and quantity of cover.
  • Vegetation and residue combinations that completely cover the soil and intercept all falling raindrops at and close to the surface are the most efficient in controlling soil erosion (e.g., forests, permanent grasses).
  • Partially incorporated residues and residual roots are also important as these provide channels that allow surface water to move into the soil.

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.
Riparian vegetation [the green band of vegetation along a watercourse] can help stabilize stream banks; filter sediment from surface runoff; and provide wildlife habitat, livestock forage,and scenic value. Well-developed vegetation also allows bank soils to absorb extra water during spring runoff, releasing it later during drier months, thus improving late-summer stream flows. In many parts of the arid West, trees and shrubs are found only in riparian areas. Woody plants are very important as winter cover for many wildlife species, including upland game birds such as pheasants and turkeys. Often this winter cover is the greatest single factor limiting game bird populations. Woody vegetation also provides hiding cover and browse for many other species of birds and mammals, both game and nongame. Dead trees ("snags") are an integral part of streamside habitats and should be left standing whenever possible. Woodpeckers, nuthatches, brown creepers, and other birds eat the insects that decompose the wood. These insects usually pose no threat to nearby living trees. Occasionally a disease organism or misuse of pesticides will weaken or kill a stand of trees. If several trees in a small area begin to die, contact your local extension agent immediately . How dependent are plants and animals on each other?
