As there is an ecological gradient from north to south in the Western Ghats with changes in diversity and species richness as well as physical features, a normalization for every state was done for these parameters. Thus, scores were normalized for each state. For instance, the highest recorded altitude in a given grid in a state was given the maximal score and all other grids in that state were ranked in relative fashion. After normalization ranks were assigned on a scale from 1 to 10 based on the maximum value of each parameter for each state.

Subsequent to the rank generation, the average of the ranks for all parameters were calculated. If, for a grid, there is data for only for 5 parameters out of 8 parameters, then dividing the sum by the number of parameters assessed took care of the problem of data available for variable numbers of parameters per grid.

d. For arriving at ESZs, the grid scores were treated thus:  

 the lowest quartile (approx. 25%) of these scores for grids was computed. For Goa , this score is 3.14 which means all grids below this core are assigned to ESZ 3. For Goa there are 12 grids under ESZ3 , which constitute about 22% of the area.
