Himalayan Yew is an important plant for medicinal plants found in various parts of Himachal Pradesh and Arunachal Pradesh. It has been characterized as endangered by IUCN due to 1. Depletion of an inter-species gene bank of Yew. 2. Threat of bio-piracy. 3. Soaking of groundwater in areas where it is present.

Himalayan Yew is an important plant for medicinal plants found in various parts of Himachal Pradesh and Arunachal Pradesh. It has been characterized as endangered by IUCN due to 1. Depletion of an inter-species gene bank of Yew. 2. Threat of bio-piracy. 3. Soaking of groundwater in areas where it is present. Correct Answer None of the above

The correct answer is None of the above.

Important Points

  • Yew has undergone a recent, range-wide population decline of at least 50% as per IUCN. 
  • Throughout its range in the western Himalayas, it is declining in response to a range of threats.
  • In Afghanistan, up to 50% of the forests where it occurs have been destroyed or heavily logged (UNEP 2003) over the last 30 years.
  • In northwest India and western Nepal, exploitation associated with Taxol production has led to a national decline of up to 90% in Taxus populations throughout the country.
  • Also, in other countries such as Pakistan, overexploitation for fuel, fodder, and medicinal use has led to a significant decline.
  • The decline is continuing and while the causes are largely understood, in many areas they will not be reversible. On this basis, an assessment of Endangered is warranted. So, options 1, 2 and 3 are NOT correct.

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 . What is the overall sense conveyed by the author when the specific birds that live in riparian areas are listed in the passage?
