One approach to biodiversity measurement is fitting a distribution to species abundance data. In the present case data on abundance of different species is recorded at two Indian localities in western-ghats (Arvind and Dhoni). These data are said to be 'Frequency of frequency'. Some ecological considerations suggest that a log-normal distribution should fit the data. S - the number of species observed and area under the curve to the left of 1/2 are used together to estimate the number of 'unseen' species.
