FLORA OF TAMILNADU

• The Indian region with a total area of about 328 million ha is very rich in biological diversity. It is estimated that about 45,000 species of plants occur in the country. 

• The Vascular flora, which forms the conspicuouse vegetation cover itself comprises 15,000 species, of which more than 60% are endemic and have so far not been reported from anywhere else in the world.

• The total plant wealth of the country includes not only the usually large, showy-flowered vascular plants, but a large number of non-flowering plants, viz. ferns, liverworts, algae and fungi.

• The wild relatives of crop plants along with related species as well as the species of economic plants (estimated to be over 150) are in themselves very valuable gene pool.

• Inventorization of floral and faunal distribution continued under the aegis of the national institutes of Botanical Survey of India and the Zoological Survey of India across the country and with every subsequent survey, new and unknown species of plants and animals came to be identified and added to the list.

• Tamil Nadu's diversity was also surveyed during the course of investigations by researchers from other scientific institutions.

• Gamble (1935) enumerated 4,516 species in the then Madras Presidency, while after the State's reorganization 2,260 species belonging to 983 genera and 173 families have been described in Tamil Nadu and Carnatic region (Mathew et al. 1981).

• Besides, they have also reported 111 species of Pteridophytes from 59 genera and 11 species of gymnosperms from 9 genera and 5 families. Subbarayalu and Velmurugan (1999) have described 202 species under different IUCN categories of threat. Of this 45 species are endangered, 53 possibly extinct, 29 vulnerable and 75 rare.

• The Angiosperm diversity of India includes 17,672 species. With 5,640 species of flowering plants, Tamil Nadu ranks first among the States in the country in angiosperm diversity. It accounts for nearly one-third of the total flora of India. This includes 533 endemic species, 230 red-listed species, 1,559 species of medicinal plants and 260 species of wild relatives of cultivated plants.

• The gymnosperm diversity of the country is 64 species, of which four species are indigenous Gymnosperms and the rest are introduced species.

• The pteridophyte diversity of India includes 1,022 species of which Tamil Nadu has about 184 species. Tamil Nadu's wild plant diversity also includes vast number of bryophytes, lichens, fungi, algae and bacteria.

• The analysis provided the total number of plants in Polypetalae, Gamopetalae and Monochlamydae to be 1,944, 1,720 and 642, respectively. Distribution of plants in different plant taxa shows there are a total of 4,306 dicots and 1,241 monocots.

• India is represented by a wide array of faunal species. More than 50,000 species of insects, 4,000 of molluscs, 6,500 of other invertebrates, 2,000 of fishes, 140 of amphibians, 420 of reptiles, 1,200 of birds and 340 of mammals, totalling more than 65,000 species of animals are recorded from the country.

• Tamil Nadu's faunal biodiversity is equally impressive. Dr. K. Venkataraman of Zoological Survey of India, Chennai has published about 595 species of freshwater faunal, 2,247 species of marine faunal and 1,898 species of terrestrial faunal species in Tamil Nadu.

• The faunal diversity of the State includes 165 species of fresh water fishes, 76 species of amphibians, 177 species of reptiles, 454 species of birds and 187 species of mammals. According to the CAMP reports the red-listed species include 126 species of fishes, 56 species of amphibians, 77 species of reptiles, 32 species of birds and 40 species of mammals.

•  The endemic fauna includes 36 species of amphibians, 63 species of reptiles, 17 species of birds and 24 species of mammals. Many faunal species have been included in the various schedules of the Wild Life Protection Act 1972, considering their endangered status. Schedule I animals include 22 species of mammals, 42 species of birds and 9 species of reptiles.

• Schedule II includes 13 species of mammals. Schedule III includes 5 species of mammals and Schedule IV includes 5 species of mammals, 367 species of birds, 109 species of reptiles and 23 species of amphibians. Schedule V incorporates 13 species of mammals and 1 species of birds.
