number of grids at different threshold level showing sampling in-/ sufficiency in Indian mainland.
Fig 1.
Spatial representation of sampling: Insufficiently sampled grids at various threshold levels (mentioned on top) for 1° and 2° grids; it may be noted that all the grids those remained insufficiently sampled at 2° are bound to remain insufficiently sampled at 1° [*1° grids are shown under the backdrop of 2° grid].
Fig 2.
Clench fitted species accumulation curves for (a) 1° grid and (b) 2° grid (attaining asymptoteness); *Highlighted in black color shows grid at 2° scale (a and b values shows no. of observed species, no. of asymptotic species (in brackets) and; total no. of sampling plots for the particular grid).
Fig 3.
Spatial representation of insufficiently-sampled grids showing sampling priority based on the cumulative measures of heterogeneity and area.
Red indicates high priority grids and blue indicates low priority grids for additional sampling.
