To conserve and to maintain the habitats of plants and animals and prevent their extinction damage to the food chain.

  • To reduce the stress on resources and rapid depletion of resources through conservation of the environment.
  • To  protect the natural habitat of organisms.
  • To reduce the export of rare and threatened species.
  • To maintain the ecosystem stability.
  • To build and maintain  protected areas for threatened species.
  • To educate the people about the need to protect and conserve the environment as a long range  goal for the welfare of the future generation.
  • The environmentalists being aware of the importance of forests are constantly conserving the forests. This will conserve all the plants, animals and microorganisms. Forests being renewable resources will continuously supply of useful plants and animals, if used properly.

    A threatened species is a native species that is at risk of becoming endangered in the near further. A threatened species may have a declining population or be exceptionally rare. Like endangered species, the cause of its decline is variable, but may be due to threats such as habitat destruction, climate change, or pressure from invasive species.

    International Union for Conservation of Nature (IUCN) a natural resources:

    Works towards assessing the global conservation status of plants and animal species. It maintains a comprehensive list shown as IUCN Red list of threatened species. The use of this red list are:

  • Developing awareness about the importance of threatened biodiversity.
  • Identification and documentation of endangered species.
  • Providing a global index of the decline of biodiversity.
  • Defining conservation priorities at the local level and guiding conservation action.
  • Red Data Book : It is the state document established for documenting rare and endangered species of animals, plants and fungi as well as some local sub - species that exist with in the territory of the state or country. This book provide central information for studies and monitoring programmes. Species are classified into different categories of perceived risk. Red Data Book has pink pages for critically endangered species.
