Based on the survey and exploration as well as herbarium and literature studies, about 1500 species of flowering plants and few hundreds of Pteridophytes, Bryophytes, Lichens and Fungi have been identified as threatened. 

Biodiversity andits conservation are now vital environmental issues of international concernas more and more people around the world begin to realise the critical importance of biodiversity for our survival and well- being on this planet.

Biodiversity conservation may be in situ as well as ex situ. However, when there are situations where a plant is endangered or threatened and needs urgent measures to save it from extinction, ex situ (off site) conservation is the desirable approach.

  • In in situ conservation, the endangered species are protected in their natural habitat so that the entire ecosystem is protected.
  • Ex situ conservation methods include protective maintenance of threatened species in botanical gardens, tissue culture propagation and cryopreservation of gametes.
