During the successive five year plan periods, the functions of Botanical Survey of India were further diversified to include various new areas such as assessment and inventorisation of endemic, rare and threatened plant species; evolving conservation strategies; studies on fragile ecosystems and protected areas like Sanctuaries, National Parks and Biosphere Reserves; monitoring of changes in floristic components; ex-situ conservation, multiplication and maintenance of germplasm of plant genetic resources, endemic and threatened species, wild ornamentals, etc.; ethnobotanical and geobotanical studies and the development of National Database on Herbarium (including Type specimens) live collections, plant genetic resources, plant distribution and nomenclature. The aims and objective of the department were redefined, reviewed during the year 1987 and survey and exploration of plant resources and inventorisation of threatened species, publication of National and State Floras and development of National database were given top priority.

After the ratification of the Convention on Biological Diversity by the Govt. of India in February, 1994 a greater role for Botanical Survey of India was envisaged, particularly with reference to the article – 7, 8, 12, 16 of the convention. Following which the objectives and strategies of the Botanical Survey of India were further diversified. Following are the main objectives of Botanical Survey of India:


  1. Exploration, inventorying and documentation of phytodiversity (including non-flowering plants) in general and protected areas, hotspots, fragile ecosystems and sacred groves in particular; publication of National, State and District Floras.
  2. Identification of Red list species and species rich areas needing conservation; ex situ conservation of critically threatened taxa in botanical gardens.
  3. Survey and documentation of traditional knowledge (ethno-botany) associated with plants.
  4. Develop a National database of Indian plants, including herbarium specimens, live specimens, botanical paintings illustrations etc.


  1. Revisionary/Monographic studies on selected plant groups.
  2. Qualitative analysis of nutritive value of ethno-food plants and other economically useful species.
  3. Capacity building in plant taxonomy through refresher courses and post M.Sc. certificate course.
  4. Environment Impact Assessment of areas assigned to BSI for study.
  5. Develop and maintain Botanical Gardens, Museum and Herbaria.
  6. Preparation of Seed, Pollen and Spore Atlas of Indian Plants.
  7. Repatriation of Indian Biodiversity Information held in herbaria/museums abroad.
